So I currently have a setup I built back in January of 2012 and it has run great since than with a i5 2500k cooled by an antec h20 620. A few days ago my CPU skyrocketed to 90-100 degrees C and reaches 90 while sitting at the bios. I was running overclocked at 4.4 Ghz and only hitting 60 celsius during gameplay. I have returned it to stock speeds and default bios presets and it still continues to reach the 90-100 degree range. I have also tried using the stock CPU cooler that came with it and the result is even worse. Initially I thought the issue was my cooler and now I can only imagine it must be related to either the CPU or the MB.

If anyone has any suggestions please let me know because at this point Im not sure where the problem is coming from.

Thanks,
Chad

I don't know if a broken temp diode is a common issue or not.
Did you change the heatsink's thermal paste with a fresh one before you used it?
(i'm talking about the stock one, when you placed it back)

An easy way to see if the problem was related with the cpu cooler was to make your pc lie down with the cpu cooler vertical not horizotal to the floor, but you bypass that point.

What is the cpu voltage in bios and what is cpu-z is giving? i crossed a problem like that once and the cpu voltage wasn't even correct with the bios values, is not easy to see it without the right equipment anyway the problem was the battery power...

Check to see if the jumbers for the battery are ok, a digital polymeter can be proved really valuable in these cases, but i suggest to get the box to the store while still is under warranty.

I removed the maufactureres thermal paste and reapplied. I also did new thermal paste on the water cooler and neither had any effect

Hmmm well CPU-Z is showing my core voltage jumping all over the map from .992 up to 1.38. Not sure if that means anything

Well heres the report form CPU-Z, maybe itll help. Its at 4.4Ghz overclock right now which i brought down form the 4.6
