|A little while back my computer starting spontaneously shutting down. After a while I noticed it seemed to be related to heavy load which led me to suspect heat. I couldn't seem to get any readings within Windows but eventually I got around to checking in the BIOS and saw it was pretty close to 70C, the shutdown point and about the limit of the CPU when I looked it up. Eventually things got worse and I basically can't use the computer now.|
It's an AMD system, not sure of the exact CPU (bit hard to get when the box doesn't stay up long) but the motherboard is MSI Socket AM2 N1996. The cooler is a SilentFlux Media.
To me the heatsink didn't seem too hot which led me to think of the sink, paste or connection not conducting properly, so I set about removing the sink. Unfortunately the CPU came out with it with a few bent pins but after some finicky straightening work I think it's in order again.
Anyway I cleaned with CPU and sink with Isopropyl, figured out this ridiculous contraption of a cooler and reapplied new thermal paste. However the problem persists.
All fans in the system seem to be operational, including case fan, PSU fan and the CPU fan inside the cooler unit.
While the sink was off (and the CPU being blown with a big external fan) I put my finger on the CPU and verified it was indeed really hot when the BIOS said it was, so I don't think it's a dodgy thermometer.
So that leaves me with a hot CPU and a not-particularly-hot heatsink. Which leads me to think either (a) something's dodgy with the heatsink or (b) my expectation of sink temperature isn't quite right given it's not solid.
I have read about these heatsinks not being simple lumps of metal but actually having liquid inside so I wonder about the possibility of leaking ... this system is a few years old I think (I bought it off a friend). Do these things need replacing?
Voltages seemed okay in the BIOS though I'm not knowledgeable enough to be sure.
Other than that I'm running out of options, not sure what to Google even. Thoughts?
