Just bought some arctic silver thermal paste and put it on, then reattached the heat sink and still having the same problem. Right by the heat sink there are these metal squares on the motherboard with the letter and numbers R50 on it that are pretty warm too.
It has to be overheating/power supply. Any ideas?
Those squares are power phases and they usually do get pretty hot.
1) You are using to much or to little thermal paste
2) You aren't attaching the heatsink right
3) Your voltages are to high
