GPU temps back to high after few days of changing thermal paste

Shani

Recently bought a used XFX RX 570 and temps were touching 80C@80% fan speed. Decided to change thermal paste because previous thermal paste was dry. After changing the thermal paste the temps dropped to 73C@70% fan speed. But after using it 4 days, the temps are back to high i,e 80C@80% fan speed. I did take apart cooler after freshly applying thermal paste because I forgot to attach backplate. What could be the reason? Is it becasue of taking it apart after freshly applying thermal paste?

What paste did you use? Also did you take into account, that if your testing from cold boot vs using the pc for hours makes the temp go up? Also ambient temperature is a factor.

I used GD900 (chinese thermal paste). Used that paste on many other GPUs and the performance is really good. Both time tested it from cold boot. Ambient temperature ranges from 23-27C.

Is it possible the GPU is just boosting to higher speeds with the new paste?

gpu is going to get hot regardless of thermal paste applications, thermal paste just lets the card, don't worry to much. check the voltages, fan curve, and clock speeds to see if those might be having an effect.

GPU keeps stable 1286mhz even at 83C. It doesn't thermal throttle. But the temps are just very high for my comfort.

Card is at base clock speed of 1286mhz. Didn't overclock at all. Fan speed is max @80%. At 100% speed the card sounds like a blower.

Before applying the new paste too?
Because what I am thinking, is that now that the card has more headroom in terms of temperatures, it just casually is able to hit higher speeds.

What about airflow in the case?  I was looking at some reviews on the RX570 and they showed upwards on 74 C on test benches depending on the card.  I could easily see the temps going up to 83 C inside a case, especially if that case was a bit airflow restricted.
