I recently had to RMA my new PC' power supply and my only choice was to use my old PC for replacement.
The thing is that my old GPU's temperature, MSI NX7600GT, is rising steadily while idle. It stops at 60C and while playing a game, it goes up to 68C, so only a small increase. The thing is, this GPU only has passive cooling, so no fan at all.
When it was at 60C, I touched the heatsink and it was quite warm but not hot enough to make it unbearable for the skin. My question is, is it worth replacing the thermal grease on the GPU? Will it make a difference if the heatsink is absorbing heat?
I believe that the high idle temp is also increasing the temperatures of other components. CPU idles at 38-42C and HDD at 36-38C. Power supply sits at a happy 32C since it's so far from the GPU and recently cleaned it properly. I have a case fan at the back that's working at high speed if anyone is wondering.
