Ok, so i'm running Prime95 to test my new thermal paste. There is one temperature in HWinfo by CPUID. One says "CPU" and it reads 64c. The other is under a tab called "FX-8320" and says 53c. Which one is the core and which is socket? And how long does it take for Arctic Silver 5 thermal paste to set in?
