Phenom II suddenly idling at 88 C???

So my wife told me the other day that while she was using my desktop that "the screens suddenly turned off". So I went and turned the PC on to check the graphics drivers (new video card) and I could get to the desktop for about 15 seconds before both screens went black.

So I checked the bios and my CPU (Phenom II 955) was reporting 88 C! So I let it cool off for an hour and went straight into the bios and watched it climb steadily from about 33 C to 80 C before I shut it down. I decided it was a broken water pump and have just now replaced that pump.... But the problem remains. I know the pump is working (it's loud enough) and my GPU is staying cool at 34C (Radeon 7970).

Has my CPU finally snapped? I've had it for over three years now and well...I was planning in an upgrade soon anyways, but this is just weird.

Thanks in advance,
Shawn

--------------EDIT----------------

My loop is set up like this:

pump/res --> CPU --> Radiator 1 (dual 120) --> GPU --> Radiator 2 (dual 120) --> pump/res

System specs:
ASUS Sabertooth 990FX
AMD Phenom II 955
32 GB G.Skill DDR3-1866
AMD Radeon HD 7970
256GB Samsung 830
2TB WD20EARX drive
850W XFX PSU

And the award for biggest idiot of 2012 goes to... ME!

Turns out that one of the CPU waterblock retention screws came unscrewed from the motherboard backplate. Temps plummet back to acceptable water-cooled temps when I press down on the block. Anyways, it seems the screw is slipping all the way through. Time to head to Lowes to find a nut! Should fix the problem.

lucky you caught it , I had an Opteron 185 melt down after running at 85c for a week or so . Comp kept shutting down , does the wife or son mention the fact it's shutting down ? No they keep using it till it won't turn back on , then they tell me .
Good luck with yours .

That's rough man. I was actually really surprised that Windows was still running at 88C! My CPU used to bluescreen at like 66C when I was air cooling.

i would suggest to get you a new set of screw and a backplate,if you put a nut on take one that have nylon lock in and the smallest in height so it wont touch the case and made short to ground http://www.germes-online.com/catalog/17/789/page10/2756... and dont tight her to much or you could break your motherboad also repaste since you will have fix the cooler back .


Thanks for the great advice! I should be good on the hardware I got. I'm back running in the 40's! Just need to tweak for maximum performance!
