I had been having some trouble with seemingly random crashes and allot of noise from the cooler fan, especially when watching videos. I cleaned the heat sink and put new thermal paste and ran Prime95 to test stability.
What I found was that while the fan was way quieter, the cores where running between 91*-100* Celsius, and their frequency was being throttled from the CPU's rated 2.4Ghz down to 1.6Ghz. I used CPUID HWMonitor to view CPU frequency and the temps.
I ran Prime95 for about an hour, and while the computer didn't crash, the temperatures seem excessively high, and I would think the cpu's would be able to run at 100% load full speed even with the stock cooler.
Does this behavior indicate a failing CPU?
