I've been having some computer trouble in the last few days. Windows would randomly freeze for half a minute or more. Restarting the computer would take longer than usual. Internet connectivity would be an issue.
After some troubleshooting I found out that my CPU temperature was shooting over 90 degrees Celsius! So, my processor, instead of melting, was severely throttling itself which would cause the system to become unstable. I cleaned up the PC and reinstalled the CPU heatsink and it didn't help much which means that Intel provides crappy heatsinks with their processors. Not cool.
I went and bought a new heatsink from Noctua. Now, the temperatures are in the 30s. After some CPU stress testing, the maximum was ... 51 degrees Celsius.
