So I have this very unusual problem with my CPU overheating in a way that makes absolutely no sense to me. Basically a few months ago I noticed my computer running very slowly, I have CoreTemp installed and checked that and indeed all cores were at 90-100 Celsius while gaming and wouldn't cool down when idle.
I have this CoolerMaster water cooling thing with a fan attached and another fan at the opposite end of my case, I lifted it, replaced the thermal paste, and then the temperatures were back to normal. That is, until a month later, when the problem re-appeared. I did the same thing despite the thermal paste being fine obviously and the cooler clearly not being detached but somehow it fixed it again, until a few weeks later, it kept coming back faster and faster and today I couldn't fix it the same way anymore.
I had checked everything three times today, each time cleaning all the dust with an air can, stretching the water cooler pipes in case that was it, let it cool off, but every time I started the computer again the temperatures would be at 65°C while idle and quickly shoot up to 90°C+ whenever I did anything.
I removed the glass side panel and felt the pipes for pressure, and I could feel the water coursing through it, so water cooling worked, both fans were spinning normally, albeit too slowly for the heat, and nothing was detached. So just what caused the overheating? I had no idea and simply turned the computer off.
A few minutes later I turned it back on just checking for a miracle, and yep, literally randomly fixed itself. NOTHING changed, I simply turned the computer off and back on again and somehow the temperatures were at 30°C. Literally nothing changed, I can see the fans spinning the same as usual, the water cooling pipes feel the same way when I pinch them, yet somehow everything is 30°C cooler.
So I mean, what could it be? The only thing clearly not working correctly is the fan, which didn't bother spinning any faster even while my temperature was 90 degrees, but right now it's spinning roughly at the same speed it was while overheating. It doesn't look it could have caused a 30°C difference. And if it is the fans, why do they randomly decide to work sometimes but sometimes don't? Any ideas?
EDIT: so it's getting weirder now. detaching it and re-applying the thermal paste still did nothing at all. But now there is a new nonsensical way to fix it. The only thing that has worked so far is if I:
1. detach the glass side panel
2. touch the fan with my finger so it stops spinning for a second
3. turn the computer off and back on again without the side panel
This has now lowered my temperatures from an idle 65°C to an idle 33°C, twice in a row. Simply turning the computer off and back on again has not worked multiple times, it's only when I took the side panel off and touched the fan. Could be a coincidence, I really have no idea
