OK, maybe this is going to be a stupid question. Which one is really the one I any PC owner should be worry about. Fahrenheit or Celsius? I'm asking because I have seen my CPU running at 80-90 F and people said that the temp is really bad for a CPU. Well, my CPU has even gone up to 100 F and I decided to buy a new fan, but now that I installed it, it says 90 F and 35 C. Am I going crazy or the CPU is freaking HOT! If the real temp I should be looking at is Celsius, then why did my computer show me an error of CPU overheating? When It showed me that, I didn't look at the Celsius, only Fahrenheit. I know this is a confusing story but I'm really nervous. Also, I got another problem. Why is the PC freezing? It has not viruses, not errors shown, except for the CPU overheating. Also, everything has been working fine. The past 4 days, the PC has been freezing for several times. If I click at something, or a program, everything will freeze. It takes up to a minute sometime to get to normal.
