[SOLVED] Idle temperature stays relatively high after closing a game ?

So, I have a MSI Ventus 3X OC RTX 3080. Whenever I boot the computer, idle temperature is around 35ºC, which is fine. When I'm playing, temps are usually around 65ºC (I use a custom fan curve in MSI Afterburner, which has 85% fan speed for 65ºC). However, when I stop playing, temperatures don't go back to 35ºc. Instead, they hover around stable 54-55ºC. Anyone knows why this happens, and if it is safe?

Anything below 80-85C is more than safe. When you boot in windows the GPU is cool because it was not in use. After gaming it will take some time to cool again to a temperature close to 40s IF you have the zero rpm function off. If it's on, then you won't get lower than 50s easily as the GPU fans start in temps above 55-56 usually.

That's interesting. So, fans were definitely working at 54ºC, but I guess just enough to maintain a stable temperature. I manually increased fan speed, and I got it as low as 38ºC. Then, I put the fan speed back on automatic again and the fans stopped. However, temperature went back to 54ºC and at some point the fans started working again, so I'm back at the stable 54ºC - 35% Fan Speed. I guess that's a safe temperature, according to what you said. I don't remember seeing this behavior on a GPU before, but maybe I just wasn't paying attention. Thanks for the fast reply tho!

Yes, that's how most modern GPUs work when it comes to fans. But as I said, most. Some do not have that function, it's up to manufacturers if they include it or not. Even the same manufacturer include it in some versions and not in other. For example recently I saw that asus did not include it in the "TUF" version and did in "ROG Strixx".

GPU is still used while you are browsing the internet, watching videos or opening a program, so the temps rising again when you stop the fans is expected.

Those temps are more than fine, you got nothing to worry about.
