My CPU has been running SUPER hot for a long time now, could I have done some type of damage to it even though its still on?

It has apparently been running at like 100+ degrees Celsius every time I play a game. I knew it had heat problems but not like that. Could I of damaged my CPU without knowing it and have I screwed myself? It runs fine around 50-60 degrees when doing nothing. But I still don't like that :p

A buddy of mine traded PC's with me a while ago because he recently had a kid and hasnt had as much time to game and knows ill enjoy his higher end PC than he his. However he told me it had been resetting due to what he thinks was overheating. Me being irresponsible and dumb I didn't do anything about it because everything was working good. However I just barely ran into this problem of it turning off but VERY rarely. In my bios it showed my CPU was running at like 102 degrees Celsius. After further checking and testing I see that every time I play any game my temp sky rockets to 100 Celsius . I'm redoing the thermal paste on the cpu and going to clean out my liquid cooling radiator and such so hopefully that will solve the problem I should of solved long ago.

  1. reapply the thermal paste and clean up of the dust
  2. It's possible, but most usually if it gets too high it will throttle down to avoid damage or reset as indicated, so if it's running okay, when not under load, you're probably still fine. Just reapply paste and clean it up ASAP.

    Ok so I applied the paste pretty generously but not too much and sprayed out the fans / liquid cooling radiator. Its around 70-75 Celsius now when playing games , will this be fine? I don't know if theres much else do do, i'm not too great with the internals of computers so its sketchy for me to be getting down with it anyways because I don't want to break anything. Everything seems to be ok but there was some tugging and pulling that had me nervous when removing the liquid cooling system. How can I tell if my system is actually pumping and keeping cold?
  4. The only time you do damage to your CPU, is when you go above TJ Max, which takes a lot of effort to even reach fast enough before it starts throttling/reduce heat. You'd have to intentionally increase the voltage really high to instantly fry it. My AMD FX-6300 got the real stress test. I pushed 1.6v (don't try this), just to test this because people said that instantly fry a CPU is common, which on the AMD it sure isn't, or is more common with Intel, either way. All that happend was that the computer wouldn't boot fast enough to get to BIOS to revert the settings before it shut down again. However, there are other ways to revert back to default and really no harm was done. It's still running today, that was 1 year ago. With that said, I don't think you should worry too much.
  5. Depends on what make/model your CPU is, but for most that temp is fine while under load. The fact that you dropped 30 degrees is a good indication that you've probably solved the problem. If you want, you can take the side off of the case and blow a floor fan directly into the PC, if the temps drop significantly more then you need some more cooling fans in the case.
  6. Not sure if you both will see this but I appreciate the help ! I'm going to keep monitoring it to make sure the heat doesn't spike higher than 100C at most. I'll definitely invest in more cooling if that's what it takes. One more question, me and my rookie friends where a little aggressive when disassembling it I wanna make sure that I didn't mess anything up. If everything is running fine I should be fine right? My brother took the computer and programming route and im stuck clueless so all your help is much appreciated.
  7. If you damaged your CPU, your computer wouldn't be able to boot into Windows.
  8. If it's running fine otherwise, then *almost* certainly you didn't break anything, with electronics, outside of a few exceptions, things either work or they don't if damaged. That doesn't mean you should abuse them more than necessary of course ;-).

    Ok this is weird, it's still running super hot apparently. Checked todays and each core was 100+ degrees celsius, not sure whats going on. I cleaned off the old paste and applied a pea sized generous amount onto it and sprayed out the cooling radiator really good. Any other advice on what could be causing this?
