Re: Backplate EVGA 2080 and waterblock

Hi, I have a 2080 XC (not ultra) watercooled with the ekwb block and backplate and the temps are too high i think... This is the setup: Loop: * EK-vector block for 2080 * EK 360 rad with 3 ek vardar fans * EK D5 Pump. The RTX is with a i7 4790k @ 4.5ghz. The gpu runs between 2000/1900 mhz (depends game and test) and the RAM @ 7700 The fans are at 45% 850/900 rpm, and the pump is at full speed. The temps are about 70º/73º celcius with some test, heaven, valley. I wait until the temp is stable, tipically after 10 minutes. I expected better results, something like 55/60º with a silent 800rpms fans. The CPU is at 40º ever, with a burntest it can reach 50, not more... I have tried with thermal grizzly kryonaut and thermal grizzly conductnaut (liquid metal) with same results. And one last thing (It has surprised me a lot): If i put the fans at full speed, the temps are the same....... ¿may be the block is not doing a good contact? i checked the thermal paste and it seems to be well crushed ..... Sorry for my English...

That is terrible! You should be like seeing 30-40c on load for GPU temps. Single loop with CPU block? What CPU block? Is the block very restrictive and slowing the flow to the GPU block? Rad fans in push or pull?

HI, thanks for the response The fans are pushing air to the rad and outside the case. Another 3 fans are intaking air. The air path is: Outside->intake fans->case->rad fans->rad->outside The CPU block is Ek too, and the temps on the cpu are very good, 40/50 for a 4790k at 4500mhz i think it's good. The order on the loop is: res->pum->gpu->cpu->rad, therefore the flow goes direct for the gpu, and it must be good on gpu, at least, better than on cpu. isn't it? May be the thermal pads are too fat and no good contact between gpu and block? they are placed like manual shows.. See Attached image, the rad is on top. And the pum at the left. Without load the gpu is at 28/30º (25 outside)... Added detail pñic of the backplate, it's very very beautifull...

Yeah those aren't so great H20 temps. I would expect anything in the 35c-50c range of course all dependent to ambient air temp, case air flow, adequate rad and flow, etc.

It sounds like you either need to tighten the screws around your card or you need to redo your thermal paste.
How did you apply the thermal paste? What pattern did you use?

Please take pictures of the thermal paste as you take it apart. I like seeing everything. Also, spread your thermal paste. I use the edge of a credit card so that I can make it thin and even. It is extremely important that every little piece of the die is covered. Not even a tiny corner can be bare.

Hi again. I have replaced again the thermal paste: P1- a little drop, P2- After putting the block and press it with hands, no screws. Seems it do a good contact with the die. P3- Spreading manually the corners. Now, after a 20 min with MSI Kombustor, ...63º...10 min of Heaven..:54º , seems temp have dropped 12 o 13 º Playing SCUM (before 70) now 53...it seems better. Now i have a little of coil whine.. before, with air, I didn't ear it...may be the more silent?, worst phases cooling? Added pics...

I just wanted to add I also got the 2080 ti FE and EK Fullblock with backplate..
Before with Air I did not have any coil whine, or at least not noticeable... but after watercool conversion I have VERY LOUD coil whine when under full load...
And I did recieved the updated "kit" where inductors/coils thermal pad was included..
Its such a disappointment with the whine when spend so many money on gfx card and waterblock etc..

I'm pretty sure that my coil whine gone from 0 to some noticeable when going to water.

Well my coil whine varieres depending on app/ game....
But the WORST of Them all are Heaven benchmark and 3DMark11 benchmark
It sounds ridicoulus .... try thoose out and let me know?
Aldi i Think the fan from air cooling did mask some of the coil whine and also the fact that watercooled rtx boost Much higher than air

Yes, its not that loud.. my reasons is that although always playing ultra setting with AA I also use V sync at 60fps so the card isn't that stressed as a benchmark or other full performance applications..
Also when gaming I have loud surround system masking ANY whine lol! :D But yes, in quite situations when benchmarking or you know- its incredibly annoying.

you drill out the holes on the EVGA backplate and it works just fine with the mounting hardware for the EKWB block
