Overheating randomly

6700k (I was @ 4.5ghz)


So I went on holiday recently and when I got back I noticed my computer was running slower and getting lower fps.

I checked and my cpu was no longer overclocked and its running hot (up to 90c). I cleaned everything (was dusty), and started it back up. Now its a bit cooler but still WAY hotter than it should be, and I can no longer overclock at all. My fans are going like crazy all the damn time.

My only thought would be something with the thermal paste, but I have no idea.

I plan to take my cooler off and have a look, but aside from that does anyone have any suggestions or advice?

Ok so yesterday I removed my water cooler after some gaming. Temperature was 85-95c. I take it off and I feel around carefully, and its not notably hot.

I reapply some thermal paste, make sure everything is positions correctly. No difference.

Today I turn on my computer, temps 15-20 on a low load, compared to 65-75 the day before. No idea why.

Thats not exactly accurate. Firstly the thermal paste looked completely fine. When I reapplied new paste and the cooler, the problem was still there. The next day without touching anything, its perfect.
