So I recently finally managed to get my computer up and running, after having spent a month trying to build it, and I"ve discovered that my CPU is running at 59 degrees celsius at cold , and 75 degrees when doing a few downloads/running steam/music. This seems to be WAY too hot as the computer will just shut down once it hits 80. The build has a ton of fans in it, (2 in the case, 1 for CPU, one for video card, and one on power supply), and the motherboard temp stays around 40degrees C.
I believe the problem is the thermal glue/CPU glue between the CPU and heatsink, as I had to use multiple motehrboards to get this build working, and one of the previous boards did manage to get the CPU fan turning. I've read that if that happens, the glue changes and is no longer valid. I'm assuming I need to go out and buy some, and apply a new layer to heat sink/CPU.
Consequently I need advice: What's a good thermal glue to use? How exactly to I remove the old glue/do I have to?/How do I apply it?
If you guys think that there may be a more obvious solution let me know. FYI with the cast open, the comp idles at 58/59C.
