Gpu idle at 80C After full custom Cooling of cpu and gpu

[Scorpio312]

So i recently installed a full custom loop for my cpu and gpu. Everything was fine until i saw my gpu would idle at 88c. I thought maybe it would've been my clock was a bit too high so I checked it and it was the same before i did this upgrade. I double checked my thermal pads but they are are in place. Could it be that my backplate needs them as well? I'm not really too sure because most videos i've seen don't put thermal pads on backplate. I will list my specs down below:

I5 9400f

Rtx 2060 super triple fan

32gb ram

Asus b550f Motherboard.

As for cooling

i went with the  Thermaltake Pacific M360 Plus D5 Hard Tube Watercooling Kit and i replaced the radiator from this kit with a skinny one from corsair

ive got a 420mm rad in the front of my pc.

and for my gpu block im running the 2070 nickel+ plexi gpu block from Ek.

 

If anyone has some sort of idea let me know.

try and check clamping pressure

Sorry I'm still decently new to this side of cooling, Could you possibly explain how to check there or send a video link.

[crakddx]

apologies, i cant send links or such cuz im on my potato kindle rn, i might be able to in the morning though

No worries thats all good.

What GPU block specifically and specific GPU card make/model? Can you link to it? Are you 1000000% sure its the right one for your card? Sounds like it most likely isn't since you already remounted it with checking thermal pads from your description.

For the block i went with it was this one https://www.mwave.com.au/product/ekwb-ekquantum-vector-drgb-re-rtx-30803090-gpu-water-block-nickel-plexi-ac40117?gclid=Cj0KCQiA47GNBhDrARIsAKfZ2rBmiaKXJTxKMHTsHKclVglV5t5hJQH3GxJQCz9Fg34USFPl_qnADKgaAvIvEALw_wcB as this is the only one people online suggested to fit on my card which is https://rog.asus.com/au/graphics-cards/graphics-cards/rog-strix/rog-strix-rtx2060s-o8g-gaming-model/

100% not compatible with your GPU. YOu have a 2060 card, that waterblock is for 3080/3090 GPUs... whoever told you it was compatible was puffing smoke.

Wait i wrote the wrong link im sorry this is the correct link https://www.mwave.com.au/product/ekvector-strix-rtx-2070-rgb-nickel-plexi-water-block-ac21963

 

[Skiiwee29]

ok, thats much different lol.

 

According to EKWB's official compatibility reference, that card is compatible, so you likely have it mounted wrong, or a problem with your water flow. can you post screenshots of your loop and a visual drawing of how your water flow goes?

ok, flow path looks fine. Its got to be a problem then with the mounting of the block. Unfortunately this means you will have to do a full disassembly and draining of the loop to tear down the GPU block. I assume you confirmed the temps via multiple softwares just to ensure its not a bug in whatever you're are getting the reading from?

Yup i have checked my temps on asus gpu tweak and task manager and they both give me the same readings. Should i put the thermalpads on the backplate maybe to help the heat transfer a little easier from the icu.

Check with HWInfo64 and post a screenshot.

Thats what it said for me

ok, then yea. You're block is definitely mounted incorrectly. Could be as simple as not tightening the screws enough, or using the wrong thermal pads causing poor contact of the GPU die. You did use the screws that came with the block right and not the ones from the cooler disassembly?

I did indeed use screws that came with the block as all my old screws are in a sandwich bag labelled gpu screws (old). and in terms of how tight it is, It is actually really tight so I wouldn't assume that to be the issue.

Then I would assume thermal pads in the wrong place causing a gap on the die and poor pressure as a result. You will need to disassemble and check.

Alrighty I will check them out in the morning since its getting late at my location. Thank you for all the info and help.

• did u apply the thermal paste on gpu
• is your thermal pads making contact between block & pcb components

So i did all the thermalpad placements and my temps are alot lower, but now most games i play struggle to run above 30 fps.

How much is ALOT lower.. 

 

Also, in MSI Afterburner or EVGA Precision X1, double check your power limits? For some funky reason, sometimes when I update drivers it will take my custom power limit of 112% and set it to 40% randomly.

my idle went from 88c to 60c

Thats still way to high on water. You should be idling on full custom water in the upper 20s low 30s depending on your ambient room temp.

it says that do you know how to change the power voltage
