Replace 1-20-2024: Extra detailed fan assessments had been carried out within the thermals sections. These take a look at charts had been added, and fan-speed normalized chart up to date. These modifications don’t mirror a change within the general suggestion of the cardboard.

Replace 1-21-2024: Added acoustic spectrum evaluation. Added footage confirming GPU width, fan diameter, and fan hub diameter.

 

Let’s not mince phrases: The GeForce RTX 4070 SUPER is what the GeForce RTX 4070 ought to have been a 12 months in the past. It performs like a RTX 3090, makes use of solely 220 watts, and doesn’t really feel like an enormous step backward in pricing in comparison with the technology earlier than it. The reference mannequin is $599, which is $100 cheaper than the $699 GeForce RTX 3080, whereas acting on par with the $1,499 GeForce RTX 3090. It offers 12GB of reminiscence as a substitute of 10GB in comparison with the launch GeForce RTX 3080, and helps the newest DLSS know-how. No matter AMDs worth cuts and rasterization efficiency, SFF customers are getting a extra environment friendly, smaller, and simpler to work with card for the cash with the GeForce RTX 4070 SUPER.

ZOTAC has lower a transparent path into the SFF realm with the ZOTAC GAMING GeFORCE RTX 4070 SUPER Twin Edge OC that we’re reviewing at the moment. It’s the shortest card in the marketplace. It’s solely 2-slots thick. It has good acoustics, affordable thermals, and takes nicely to undervolting. At $629.99 for the OC mannequin we examined, there isn’t even a SFF tax that Small Kind Issue Community members so generally should pay.

Let’s be very clear earlier than we start: we’re wanting on the GeForce RTX 4070 SUPER from a small kind issue perspective. I deliberately requested the ZOTAC GAMING GeForce RTX 4070 SUPER Twin Edge OC because it’s the smallest card of their GeForce RTX 4070 Tremendous lineup. Small Kind Issue customers settle for a whole lot of compromises to get their methods to this measurement, and we’re this from a special angle than a conventional evaluate. We are going to, in fact, have recreation efficiency numbers for the cardboard partially 2. Nonetheless, our conclusion will likely be targeted extra on effectivity and efficiency per liter then uncooked efficiency and worth.

As I stated in previous critiques: Small Kind Issue customers aren’t proof against wanting a very good worth. Nonetheless, it’s laborious to take an ethical excessive floor on worth after we determined to pay thrice as a lot for circumstances that use one-quarter the steel, to accommodate parts which have half the perform at twice the worth. What will we will we these spacing saving builds? Put them prominently on our desks to take up area, and complain about how loud they’re.

That stated, let’s dig into the ZOTAC GAMING GeForce RTX 4070 SUPER Twin Edge OC. First we’ll handle the cardboard itself, after which we’ll evaluate the sport efficiency of the GeForce RTX 4070 SUPER partially 2.

ZOTAC offered the cardboard as a pattern for testing however didn’t give any steering or restrictions on how and what we take a look at, nor do they exert affect over our methodology or outcomes. That is glorious conduct from an organization.

My very own private bias features a normal like of the Zotac esthetic, and I bought a Zotac Magnus EN1070 SFF PC for myself roughly half a decade in the past, that I reviewed favorably. I had a single help associated difficulty with the EN1070, and it was resolved with a optimistic final result.

 

Specs

 

 

The necessary takeaway of this are the size, increase clock, energy utilization, and really useful PSU.

At 234.1mm x 123.5mm x40.2mm, the ZOTAC GAMING GeForce RTX 4070 SUPER Twin Edge OC is the smallest obtainable RTX 4070 SUPER presently in the marketplace. It will match into a whole lot of circumstances within the 6 to 14 liter class that presently wrestle with GPU measurement and have been unnoticed within the chilly. Whereas it could’t fairly match the 211mm measurement of ZOTAC’s personal GeForce GTX 1080 Ti Mini, it additionally isn’t affected by excessive warmth and decreased clocks that the GTX 1080Ti Mini did in comparison with bigger playing cards of it’s time. The 234.1mm size is an effective compromise of GPU efficiency and cooler efficiency.

Subsequent, we now have the increase clock. ZOTAC lists this as an OC mannequin and has a lift clock of two.49 GHz vs the inventory 2.48 GHz. It’s not a serious soar in efficiency, however each little bit helps. In typical trend, the cardboard really performs far sooner than 2.49 GHz in most circumstances.

Energy utilization is listed as 220 watts, which is much lower than the 350 watts of the GeForce RTX 3090 that it performs related too. That’s extremely environment friendly, as all 4000 sequence GeForce RTX GPUs have proven themselves to be. Nonetheless, it’s additionally about 20 watts too excessive for a single fan 2-slot design such because the ZOTAC GAMING GeForce RTX 4060 SOLO or MSI Aero sequence. It’s extraordinarily unlikely {that a} GeForce RTX 4070 Tremendous will launch in a single fan configuration sooner or later. I do welcome ZOTAC, or some other firm, to show me fallacious although.

PSU Necessities: Each ZOTAC and NVIDA checklist the required PSU as 650 watts. This was fairly correct after I examined by placing the Intel I9-12900K beneath full load (Prime95) whereas additionally placing the GPU beneath full 230 watt load. I pulled 636 watts on the wall with out counting sudden energy bursts. If in case you have a decrease energy CPU, you could possibly get away with a decrease energy PSU, however I strongly advise anybody planning to make use of this card to make use of not less than the required 650 watt unit.

Design Aesthetic

Appears to be like are within the eye of the beholder, however I believe the cardboard appears to be like good. The ZOTAC GAMING brand has a nice blue LED glow, and the cardboard itself is a number of shades of gray. It’s unobtrusive however good wanting. The plastic feels ridged to the contact. The again plate appears to be like good as nicely.

Acoustics

There are a number of components that impact GPU acoustics. To get a very good baseline, we’re testing on an open bench type case (XTIA X-Proto XL body). Let’s needless to say circumstances can and do impact acoustics, and there are quite a few SFF case designs. Don’t count on the identical outcomes when you put this card in what quantities to a small sealed field as I get on an open bench.

On this evaluate we’re specializing in fan noise and the dreaded coil whine.

Fan noise is commonly heard as each the sound of the fan transferring air, sound of the motor, and sound of the bearings. Coil Whine is the sound of the assorted electrical parts on the board normally when beneath load. We separate these by first testing the fan noise and not using a GPU load. We then decide the RPM that the followers are spinning at to attain 40dBA. That is known as the fan-speed normalized 40 dBA measurement. Subsequent, we place the GPU beneath full load on the fan-speed normalized 40dBA RPM.  Lastly, we measure the distinction between the 2 dBA measurements.

Do not forget that dBA is a logarithmic measurement, and a 3 dBA enhance is equal to doubling the sound vitality being produced.

There’s one factor I need to make completely clear; these will not be anechoic measurements. The room is my own residence workplace which options tile flooring, laborious partitions, and IKEA wall mounted furnishings. The take a look at system was positioned on my work desk in a nook of two laborious surfaces which can trigger the sound waves to mirror. In essence, it is a very undesirable place to place a PC by which is why I select it.

Testing was performed utilizing a REED R8050 dBA meter that was calibrated with a REED R8090 Sound Stage Calibration Unit previous to testing. The unit was in “Lo” mode which measures from 30 to 100 dBA. Please needless to say these numbers are the typical of what I noticed in testing and might fluctuate barely.

Testing was performed on-axis to the GPU followers. That implies that the dBA meter was immediately in entrance of the GPU followers.

Testing was performed at 2 ft (61cm) distance from the GPU and 1 foot (30.5cm) elevation from the desk the GPU was resting on. This introduced the dBA meter in horizontal alignment with the GPU followers.

 

– Fan Solely dBA Goal Measurements and Subjective Notion

The target measurements are introduced on this graph.

Very first thing to notice is that the GPU doesn’t spin its followers beneath most idle circumstances. Which means it’s successfully silent towards the room and take a look at bench ambient noise degree.

At 30%, which is the minimal degree I may take a look at at, the followers had been inside .1 dBA of the ambient. This tells me that I’d be unlikely to understand a distinction between the followers at 30% and the followers off in my listening atmosphere.

With the GPU beneath no load, and simply elevating the fan velocity, the 40 dBA threshold that most individuals think about the sting of quiet was achieved at 51% or 1,791 RPM.

Underneath inventory gaming load the followers spun within the space of 55%, however extra on that shortly.

 

Sound Angle

 

The target angle information is introduced on this chart. The change is that the GPU is now beneath full gaming load triggering any coil whine to happen. The inventory fan curve and computerized fan management was used. and fan velocity was reported as 55%. Off axis measurement was performed at a forty five diploma angle away from the middle of the fan hub. Moreover, an extended distance and barely greater place was included to indicate the outcomes of distance scaling.

On this occasion a drop of 1.3 dBA was measured by transferring 45 levels off axis to the GPU. This means that the majority of the fan noise and coil whine is directed out of the GPU on axis. At an extended distance of 45″ (114.3 cm) and barely elevated top of 14″ (35.6 cm) the drop in fan noise by transferring 45 levels off axis was 1.4 dBA.

Most customers place their methods towards the nook of their desks which is often about  usually 45 levels of axis to the sitting place. This GPU confirmed improved acoustic efficiency when positioned off axis.

On axis measurements transferring from 24″ distance (61 cm) to 45″ distance (114.3 cm) confirmed a extra important discount of sound vitality by 2.4 dBA. In layman’s phrases, sitting additional away is quieter. Additionally, water is moist.

Coil whine Goal Measurement

 

Coil Whine has turn out to be pretty widespread place in GPUs. The overwhelming majority will exhibit some type of it, and it could differ from GPU to GPU even in the identical product line. It normally appears like {an electrical} buzz and ticking noise. The ZOTAC GAMING GeForce RTX 4070 SUPER Twin Edge is not any totally different, and does show coil whine. This measurement was attained by setting the GPU to it’s 40 dBA noise normalized fan RPM after which inserting it beneath full load. On this occasion, there was 42.9 dBA of coil whine in comparison with 40 dBA of fan noise. Be aware that each one different followers from the methods had been accounted for beneath this state of affairs.Which means the CPU cooler, pump, and PSU weren’t emitting any further noise themselves.

{The electrical} coil whine measured at practically double the sound vitality of the fan noise. Coil whine tends to illicit extra complaints than fan noise. As such, we’ve created a scale to display how this may impact you.

 

Coil Whine Scale

• Inaudible – Can’t be heard. The coil whine is both not current or too low to heard or measured towards the noise produced by the followers.

 

• Barely Audible – Can barely be heard and requires shut inspection to find out if the whine is coming from the GPU itself. The noise is instantly drowned out by music or video games at even low volumes.

 

• Reasonably Audible – Could be heard from a typical seating place and is clearly coming from the GPU. Nonetheless,  the sound is drowned out by gaming and music at regular listening volumes,  and can’t be heard via closed again headphones when no sound is taking part in, whereas in a standard sitting place. Metal Sequence Arctis Professional Wi-fi headphones had been used throughout testing. Most GPUs I’ve examined lately are at this degree.

 

• Audible – Clearly coming from the GPU and clearly audible at seating place. Could be heard whereas listening to music or video games at regular volumes via audio system in a desktop place. Can’t be heard over music or video games at regular listening quantity whereas utilizing closed again headphones besides in silent moments. Could be quietly heard via closed again headphones when no sound is being performed.

 

• Very Audible – Audible at seating place and disturbing to video games or gaming in any respect volumes whereas utilizing audio system. Could be heard via closed again headphones whereas taking part in music and video games at even loud volumes. Would trigger most customers to return the GPU even when provides are restricted.

 

• Faulty – Loud and clearly faulty part. Can drown out dialog, and make even loud gaming and music not possible.

 

Primarily based on the testing carried out on the ZOTAC GAMING GeForce RTX 4070 Tremendous Twin Edge, present MODERATELY AUDIBLE coil whine on the above scale. This is identical score that my very own private EVGA GeForce RTX 3080 XC3 achieved, and was quieter than my AMD Radeon RX 6900XT Reference design. Different samples might differ.

 

Subjective Sound

As a reminder, subjective assessments are these of the opinion of the tester. In essence, I’m implanting my very own private preferences and observations which can or might not align with your personal. Whereas I try to be as impartial as potential, my very own bias and bodily limitations will likely be a part of this part. This contains the very fact I’ve a minor life-long Tinnitus (ringing in my ears) within the roughly 7800Hz range. Moreover, I can not hear above roughly 16,700Hz because of my age. You may estimate your personal listening to potential with among the tone sweeps obtainable on YouTube.

Listed here are my subjective notes:

This was performed with no load on the cardboard and doesn’t embody coil whine because it was mentioned within the earlier part.

0% – 35.6 dba RPM 0

30% – 35.7 dba RPM 1030

35% – 36.0 dba RPM 1185

40% – 36.9 dba RPM 1348 (First time I may hear the followers from my sitting place. It was barely audible.)

45% – 38.0 dba RPM 1507 (A slight mechanical hum is now current.)

50% – 39.6 dba RPM 1661

51% – 40.0 dba RPM 1791 NOISE NORMALIZED AT 40dBA FAN NOISE (Audible however not loud in my notion.)

55% – 41.6 dba RPM 1824

60% – 43.8 dba RPM 1974 (Mechanical hum oscillates in pitch)

65% – 45.8 dba RPM 2145 (The pitch change resulted in a .3 variability in dba readings)

70% – 47.0 dba RPM 2302 (The pitch change resulted in a .3 variability in dba readings was extra speedy than 65%)

75% – 49.8 dba RPM 2460 (Pitch has smoothed out because of fan noise. Restrict of consolation with out background noise and closed headphones.)

80% – 51.5 dba RPM 2609 (Fan noise is dominate with slight oscillation in fan tone)

85% – 54.2 dba RPM 2775 (.5 dba variability because of fan noise and tone oscillation. Sound is unstable and unsightly.)

90% – 55.5 dba RPM 2935 ( +- 0.5 dba quickly altering tone and pitch)

95% – 56.8 dba RPM 3090 ( +- 0.5 dba quickly altering tone and pitch)

100%- 57.8 dba RPM 3240 ( +- 0.5 dba quickly altering. Tone is now excessive pitched akin to the frequency of a jet beginning up. )

My private conclusion right here is that I’d attempt to preserve the followers beneath 70% no matter carrying headphones or gaming on audio system.

After fastidiously listening to the followers I needed to do a fundamental take a look at the audio spectrum that they produced. It is a cursory look and never a full take a look at. As such I measured took readings at solely 65% fan velocity and 100% fan velocity.

 

These shouldn’t be thought of actually scientific testing as I didn’t carry out them with an authorized and calibrated microphone and didn’t carry out them in anechoic chamber. I positioned the microphone inside 6 inches of the GPU, which was mounted in aspect a Ghost S1 case on the time. After listening for the nosie, I discovered that it matched the resonance was matching the 380 Hz to 400 Hz studying at 65% fan velocity. The typical recorded quantity was considerably greater then the typical volumes of close by frequencies, and the utmost quantity was on half with the utmost quantity produced by the followers at that velocity. The hum osculated up and down by as a lot as 9 dBA. The modifications in quantity the place rather more noticeable than the pitch alone.

Here’s a sample of a 400 Hz tone.  Take heed to it, whereas growing and lowering the quantity from 25% to 100% about each 1.5 seconds.

At 100% fan velocity the tone was now at 500 Hz, which by the way is nearly the identical pitch because the engine sound in Ridge Racer on the Ps 1. Nonetheless, it’s unlikely the fan will likely be working at 100% except the person forces it too.

Primarily based on our layman’s scale, this resonance could be thought of AUDIBLE. It may be heard via closed again headphones, however is drowned out by music performed at regular listening volumes.

 

Acoustics Conclusion

The acoustic efficiency of the followers for the ZOTAC GAMING GeForce RTX 4070 Tremendous Twin Edge are excellent. The fan and cooler mixture hardly ever exceeded 55% at inventory ranges on an open bench, and will be tuned right down to nicely beneath 40 dBA whereas nonetheless preserve good temperatures. As at all times your case alternative will impact this.

The acoustic efficiency of the coil whine is common for this pattern. As at all times it varies from pattern to pattern even in the identical mannequin line. For this card, the whine was noticeable beneath load however simple to drown out and neglect about whereas gaming or listening to music. That stated, there’s room for enchancment, and I encourage Zotac Engineers to look into options for this. It’s actually the one factor stopping acoustic efficiency from being high tier for card’s measurement.

As with virtually all skinny fan designs there will likely be a resonance which displayed itself above 50% fan velocity, and within the 400 Hz vary. That is regular for thinner followers, however needs to be thought of.

 

Thermals

On would suppose thermal conduct of a card could be simple to find out, however not within the SFF world.  Most Small Kind Issue builders select their case first, and fear about airflow second. Moreover, folks dwell in various climates; with and with out air-conditioning. As such it’s necessary to consider your personal state of affairs when thermals. Take into account these a little bit of an optimum baseline.

I will likely be offering a snapshot of the thermal efficiency in my very own state of affairs, and with an open bench type construct. The ambient temperature of the room I measured in is 22-23C, although consumption temps on the fan hub might differ because of recirculation of exhaust air from the GPU itself. To place issues on an excellent floor, we’ll be 40 dBA fan-speed noise normalized efficiency as a baseline.

First let’s take a look at fan velocity vs temperature beneath full load at inventory energy. For this take a look at, I used the menu of Immortals of Aveum menu to convey the GPU as much as full load for 10 minutes previous to starting recording temps. Sure, even the menu is that demanding on this recreation. Every velocity was held for two minutes previous to recording the reported temperature.

 

At inventory energy, on the open bench with an ambient of 23.2C, we see a 6.7% lower in temps going from the fan-speed noise normalized 1,791 RPM to the three,190RPM of 100% fan velocity. Beneath 40% fan velocity, we see a considerable enhance of temps going  out of thermal limits for the GPU. Let’s see how this results clock velocity.

 

Matching the earlier chart, we will see that under 40% fan velocity we begin to see critical discount in core clock velocity.That is nonetheless nicely above the 1.98 GHz of the GeForce RTX 4070 Tremendous’s base clock, and near the two.48 GHz increase clock of the FE mannequin. Above 60% fan velocity gave us the very same clock velocity no matter temp.

Now let’s add +10% energy and +100 core clock by way of MSI Afterburner

 

Each 30% and 35% fan speeds failed on this take a look at as the cardboard bios was quickly switching between 100% fan velocity and the person enter proportion. The excellent news is that the cardboard BIOS saved the cardboard from damaging itself.

Fan-speed noise normalized was at 83C, which is on the very tail finish of the spec, and that is with an open bench. As such, I count on in-case efficiency to be within the 75% to 80% vary.

Let’s take a look at clock velocity for the OC take a look at.

 

 

We don’t see a considerable degredation of clock velocity till going under 45% fan velocity at above 85C. Let’s focus in on the fan-speed noise normalized efficiency.

 

 

NOTE: This part was retested with a better ambient temp and longer measurement time. The brand new outcomes have changed the unique.

The above chart represents that 40 dBA fan-noise normalized efficiency of the ZOTAC GAMING GeForce RTX 4070 SUPER Twin Edge. It doesn’t issue the coil whine into the equation as that varies from GPU to GPU. Throughout this take a look at, the followers had been spinning at 1,785 RPM. At inventory clocks and energy rankings, the cardboard was at 75C, with a 2,670 core clock, at full load, and whereas pulling roughly 220 watts.

Utilizing MSI Afterburner so as to add a +10% to the ability resulted in a rise from 75C to 83C. Nonetheless, it additionally resulted in a corresponding enhance in core clocks from 2,655 MHz to 2,715 MHz. The GPU was now pulling as much as 235 watts.

Including a +10% energy and a +100 MHz to the core clock resulted in the identical 83C temperature, however a core velocity of two,775 MHz. This indicated that there was potential to undervolt the cardboard.

 

Undervolting and Energy Draw

 

 

Energy draw as reported by MSI Afterburner was 220 watts at 100% load, and 230 to 235 watts with a +10% energy enhance. On the wall, with my I9-12900K take a look at rig, this yielded a pull of 365 watts and 385 watts respectively. This was utilizing to the menu of Immortals of Aveum to place a full GPU load on the graphics card, however a minimal load of usually 7% to 9% on the CPU.

Let’s see if what undervolting brings.

A preliminary take a look at of undervolting was performed to scale back energy utilization, temperatures, and noise. Within the above chart, a full load was positioned on the GPU at a hard and fast 40% fan velocity of 1345 RPM. This chart contains coil whine which was decreased considerably by undervolting. Apparently, the coil whine could also be partially linked to the fan sub-system in my pattern because it decreased when the fan was turned down regardless of the GPU being set for the inventory energy. Extra investigation will likely be wanted to substantiate this, and will likely be adopted up on in a future article.

Inventory voltage at 40% fan-speed normalized resulted in a core temp of 81C. Whereas scorching, it’s nonetheless inside spec. It needs to be famous that eradicating the handbook fan management resulted within the followers instantly spinning to 65% velocity till the cardboard cooled down.

Undervolting to 2,745 MHz at 1000mV resulted in a reported core energy utilization of 195 to 198 watts at full load, and a core temp of 77C at 40% fan velocity. This was secure sufficient to face up to 20 back-to-back handed of 3DMark TimeSpy

Undervolting to 2,745 MHz at 985mV resulted in a reported core energy utilization of 190 watts and a reported temperature of 73 to 74C. It was additionally secure with the identical 3DMark TimeSpy take a look at listed above.

In each circumstances the GPU clocked at related clock speeds because the non-undervolted take a look at, and was considerably quieter beneath load.

Clearly there’s some potential to undervolt the cardboard. On this occasion, I used it to handle thermals and noise. Nonetheless, you’ll be able to definitely use it to achieve further clock velocity on the identical noise degree and fan velocity.

 

Cooler Design

Let’s give reward the place it’s deserved; Zotac listened. The final Twin Edge card I examined was 2.2 Slots thick which restricted its potential for it for use in a whole lot of SFF circumstances. The ZOTAC GAMING GeForce RTX 4070 Tremendous Twin Edge OC is….

 

TWO SLOTS THICK.

(40.2 mm)

Thanks…

Let me share with you a bit of behind the scenes. After the RTX 4060Ti Twin Edge launched I requested Zotac immediately why it was 2.2 Slots and never 2-slots. This query made it’s approach world wide to the engineers who, I’m guessing, had heard it a number of instances already and weren’t thrilled listening to it once more. At the very least that’s my idea as a result of Zotac made positive this card was solely 2-slots. Most early SFF circumstances had been designed for 2-slot playing cards and lots of are nonetheless fashionable at the moment. Zotac made the proper alternative in lowering the cardboard to solely 2-slots.

The cooler’s top does rise above the PCIe bracket barely to the tune of a complete of 123.5mm. Circumstances such because the Ghost S1 and Dan A4-SFX will match. There’s one caveat, and it’s not unique to this card. The cardboard makes use of a 12V HPWR cable for energy, and the included 2 x 8 pin to 12V HPWR adapter provides 20mm to the peak of the cardboard when you don’t bend it.

Let me state this in no unsure phrases: DO NOT BEND the 12V HPWR energy connector. Unhealthy issues occur. Playing cards go growth or melty melty.

To your private construct, you could want a customized cable or low profile adapter to make sure the cardboard matches. Within the SFF world, this widespread place.

Size sensible, Zotac actually got here via. That is the shortest GeForce RTX 4070 Tremendous in the marketplace as of writing with a size of solely 234.1mm. The PCB itself extends just about your complete size of the cooler, so there will likely be no trimming the tip of the cooler to achieve just a few mm. Zotac made this cooler as brief as it could presumably be for the PCB itself.

The heatsink has its fins working vertically from the PCIe connector to the highest of the cardboard, and warmth pipes that run lengthwise or horizontally throughout the PCB. Which means the cooler goes to be pushing scorching exhaust air from the highest and backside, and never out of the again of the case. As such, you must preserve this in thoughts in case your NVME SSD lives within the slot beneath your GPU, and search for circumstances with exhaust followers or glorious air flow.

 

Heatsink Orientation Thermal Check

On this take a look at we flip the GPU in numerous route whereas beneath full load. This permits us to see if there are any modifications within the thermal efficiency of the heatsink relying on its orientation within the case. Up to now, we’ve had GPUs coolers work in a single route, however not one other. The EVGA RTX 3080 XC3 is an instance of this. For those who put it in a vertical orientation with the ports towards the ceiling, it can not cool the GPU.

Ambient air temperatures had been measured on the fan hub earlier than every core temp was taken. Fan velocity was locked to 55%.

 

• Vertical orientation with rear HDMI and Displayports dealing with as much as the ceiling (Xtia Xproto  or SilverStone FT-03 Mini as instance) – 75C at 55% Fan velocity with 29.7 consumption temp.

 

• Vertical orientation with rear HDMI and Displayports dealing with right down to the ground (Protolyth Slate Case or SSUPD Meshlicious as instance) –  75C at 55% Fan velocity with 29.7 consumption temp.

 

• Horizontal place with the PCIE slot dealing with up towards the ceiling as if in a reverse sandwich type case. (Thorzone Mjolnir or Lian Li A4-H20 as instance)  – 76C at 55% fan velocity with consumption temp of 32.6C.

 

• Horizontal place with the PCIE slot right down to the ground as if in a typical sandwich type case. (Dan A4-SFX or Louqe Ghost S1 as instance) – 75C at 55% Fan velocity with 29.7C consumption temp.

 

• Inverted ATX orientation typically known as reverse ATX the place the CPU could be on the high of the case and the motherboard on the backside of the case. The GPU followers would draw air from the highest of the case. ( SilverStone Sugo 16, Dan C4-SFX, NCASE M1 Neo as instance. ) – 72C at 55% fan velocity with 29.9C consumption temp.

 

• Customary ATX orientation (NCASE M1 Traditional, Fractal Node 202 in Horizontal, or Sliger Cerberus as instance) – 75C at 55% Fan velocity with 29.7 consumption temp.

 

The one notable deviation could be the inverted ATX orientation as could be within the SilverStone Sugo 16 type case. The GPU was repeatedly measuring 3C cooler on the identical fan velocity even with a 0.2C enhance of consumption temp. This means that circumstances such because the Sugo 16, Dan C4-SFX, and new NCASE M1 Evo ought to carry out nicely with this card.

 

Thermals Conclusion

The ZOTAC GAMING GeForce RTX 4070 SUPER Twin Edge has good thermals for its measurement in an open air atmosphere, and will present strong cooling in circumstances with excessive air stream. Just like the overwhelming majority of axial fan designs, this card may undergo from thermal recirculation relying on the case it’s put in in. I like to recommend a case with good air flow and a few type of exhaust. An instance could be a Ghost S1 case by Louqe. If obtainable, I’d recommend placing one of many extension  or “high hats” on the case with an exhaust fan pulling scorching air out of the case. Within the occasion of a Dan A4-CFX the place an exhaust fan isn’t potential, I’d recommend undervolting when you discover there are thermal and noise points. If neither possibility is feasible, I’d estimate that the GPU fan velocity will possible rise to 60% to 65% speeds when beneath full load. I intend to check this at a later date nevertheless it’s past the scope of this text.

 

Conclusion

Zotac has created a winner for Small Kind Issue with the ZOTAC GAMING GeForce RTX 4070 SUPER Twin Edge OC. It could actually obtain it’s full clocks, and achieve this quietly. Sport efficiency, which will likely be posted partially 2, is superb and on par with the RTX 3090. All this with a 220 watt energy draw, in a 2-slot design, and at solely 234.1 mm size.
