Hello..So I got an GTX 960 2GB..Yeah it's old. ( My PC isn't that good ) And It's on 52-53 °C Idle when just reading forums and things, Is that temperature good or not?
It sound like a) your GPU cooler is full of dust and/or b) the thermal paste on your GPU is old.
Blow the dust out of your cooler and re-paste your GPU, temps should improve.
The gpu paste was already on it but you have to replace it:O , I didn't know I have to put paste on my gpu ( the pc was already built ) Can you send me a video with a tutorial where to put the paste?
