I have bought an MSI G41M-P28 motherboard to create a mini-computer which was supposed to be mostly used for video encoding. I installed Fedora Core 15 on it, then avidemux to proceed with the video encoding. However, the computer would hang at times. I suspected an overheating, but I thought if the CPU overheat the computer would actually restart instead of just hanging for a few seconds. I quickly installed lm-sensors, and what did I noticed? After running avidemux for a while and monitoring lm-sensors, I noticed the second sensor sitting at 58~64C, and its crit being at 64. So it would basically go up to 64, halt the CPU until it reached 58, and do that over and over again. I installed Windows Server 2008 for more accurate testing, as linux was a brand new thing for me. SpeedFan reports the same thing, under Temp2. I've tested and it also happens with Prime95, so avidemux isn't the culprit. I also put the computer outside its case, to ensure it isn't related to that, but it failed running Prime95 without halting. So what/where is the Temp2 sensor exactly on that motherboard?
I have a sensor on my motherboard labeled as Temp2 on SpeedFan that keeps "overheating". Where is that sensor exactly?
EDIT: Oops, forgot the specs somehow...
Tested with Fedora Core 15, Windows Server 2008 (SpeedFan, CPUID HWM, CoreTemp, lm-sensors)
