About a day ago my desktop started to shut off randomly. After checking the CPU temperature in the bios i found the CPU temperature would hit 90c and shutoff in about five minutes of just leaving it idle in the bios status screen. The CPU fan would be running at around 950 - 985 rpm during this time. I'm assuming that the issue is with the CPU fan but thought it couldn't hurt to see if anyone else had any ideas as to what could be causing it.
