RTX 3080 FTW VRAM Temps

[Pikatchu]

I have recently changed my 3080 from waterblock back to air cooled.

 

All thermal substance were kept stock on the air cooler.

 

My only concern is vram temps, hovers around 96-100C during gaming.

Was this normal? I dont recall seeing it that high before.

 

Other temps are in place and as expected.

Nothing dangerous there for the vram temperatures, thats well within spec.
Totally safe and nothing to worry about

Hey, I have notice the test was done with an undervolt profile, at stock it is 96-100C.

I have read others VRAM are all around 10 degrees of core temp, my is almost 30

Thats warm but still not dangerous for the card. Anything under 105c for the vram is 'acceptable'

Maybe you could increase the airflow of your case or find a way to bring some more air to the GPU?
I personaly wouldn't worry even with those temps unless you do that for 24/7 operation.
You could maybe take a look into some better thermal pads, that could help quite a bit.

The stock ones are like a paste substance, not pads. Though, the paste is not runny like regular thermal pastes. It stays at its shape well.

 

What kind of substance is this? Should I replace it with the same thing or pads? Because in order to replace it with pads, I will need to remove the paste like thing.

That's thermal putty

Using pads probably fine if you use the correct thickness.

Will layering the pads be bad? Or is it okay?

 

I have some left over pads from the waterblock, though might not have the correct thickness

Probs fine if it isn't too many

Correct thickness is VERY important.

 

Basically:

Too thin and the vram & stuffs might not get enough contact with the heatsink

Too thick and the pads might prevent the GPU die (and/or other section) from getting enough contact with the heatsink

 

You want it to be thick enough that it compresses a bit when you put on the heatsink, therefore ensuring good contact.

But not too thick that it prevents other section or your GPU die from getting proper contact.

Replaced it with the thermal pads, the VRAM temps are now at 84-86, much better.
