CPU temperatures suddenly maxing out.

Hi, guys. I built a PC a few days ago and everything has been working fine. Today I opened it up just to make sure the slight clicking sound was coming from my PSU as I thought, not that it really bothers me, I just wanted to know what was making what noise. So I turned it upside down, gave it a listen, removed the graphics card, gave it a listen and everything was as I thought. When I returned everything to how it was though and turned the PC back on my CPU literally shot up to 99 degrees, maybe higher since that's the highest number the moherboard's display goes up to. Of course, I immediately turned the PC off after this. I turned the PC on it's side so I could a good look at everything and secured the CPU fan, taking it off to have a look showed there seemed to very little signs of thermal paste left, for some reason, but I returned it, switched the PC back on and the temps seemed fairly normal again. So I turned it off, returned it to it's upright position and turned it on again, only for the temps to max again. This is quite scary, do you think my CPU has been damaged at all, should I replace the thermal paste? Has anyone had any experience with this kind of thing before? Thanks for any help.

I think ur PSU hates to be put upright or something got stuck in it. UR PSU IS BROKEN

what psu is it

because it is possible that the Psu broke and is delivering dirty electricity

possibly harming the CPU

It's a Corsair CX600M. It was fine before and I've returned it to it's original position.

Replace thermal compound (clean it off first, then reapply).  Double and triple check the cooler is securely mounted.  Double check the CPU is properly seated.  Double check all power connections on both ends.  Sounds too easy, but these kinds of issues are really common.

 

If you do all of that and still get unusual temps, might be a good idea to try another PSU if you have access to one.  Seems weird that the PSU would cause CPU to overheat.  If there was a power delivery problem, I would expect to see lots of errors.

Thanks for your help. I went out to buy some thermal paste at the local shop, but decided to buy an aftermarket cooler (and used the included paste) instead, although I only had a small selection to choose from in the shop. I installed a Scythe Shuriken Rev.B and now under load, the CPU is running significantl cooler than when my stock cooler was working fine. Can I take it that my CPU survived and is still healthy, then? I've heard they limit themselves to avoid serious damage when at high temperatures.

You're fine. If your cpu ran at 99° for a while it would be a different story, but it'll be fine if you shut down right away
