High GPU temperature while playing games.

[Shmokey]

Hi.

I have a small issue. Maybe someone experienced this before. I have this RTX 3090 FTW3 with waterblock on it. I just installed it so, new paste, new thermal pads. In Idle I have 26 degrees Celsius. Whenever it loads something and the core and memory goes up, the temperature gets to 31 degrees Celsius. It creates spikes of usage and temperature in 2 seconds. When I get into a game, the GPU temperature rises to 85 degrees the GPU memory to 75 and the hot spot goes to 100. I get the same spike in the CPU. In Idle it`s 30-40 degrees the second I enter the game spikes to 71 and then goes back to 40.. I used Grizzly Kryonaut Extreme thermal paste for both. In the EVGA Precision X1 software, I get high temperatures only in the GPU not in the Memory. After I close the game, it goes back to 30 degrees in 5 seconds. What it can be?

This all sounds like normal behaviour to me. 85 C and 75 Care acceptable temperatures. Hotspot being 100 C may be a tad high even though the 3090 runs hot IIRC.

Did you repaste properly, that is, made sure the entire die was covered with sufficient thermal paste and that the mounting pressure is sufficient?

Did you use the correct thickness of pads? Is the mounting pressure correct for the CPU block? It sounds to me like a mounting issue or possibly a bad loop or not enough radiator. What is your loop configuration for the system? Full system specs and a loop explanation would help rule out the possibility of a cooling issue elsewhere.

how did you apply the paste? did you spread it across entire die or just a dot in the middle?

The paste was applyed on all the surface, not a thick layer, just the propper amount. The mounting pressure I think it`s sufficient because I tightened it with only 2 fingers untill I couldn`t spin the screw any more.

I think it`s the right thickness.. I bought today some different thermal pads and now I want to see if I need to change the size. They were all doing contact when I assemble it.

The best way to check both amount and mounting pressure, although a big hassle, would be to remove the block again and check how the paste has spread or if there are thin spots. Having a hotspot temperature might indicate some unevenness, but quickly browsing around a bit I do see more people reporting over 90 C hotspot on just a 3080 already (also with watercooling). Is your 100 C on the hotspot the maximum or the average?

It`s on average. I just did another benchmark for it and it gets to the thermal limit within 10 seconds. All the others components the power and the memory are within 70 degrees so they`re fine. Only the GPU it`s getting hot.. Should I lose the screws a little bit? maybe it`s too tightened..
