On speedfan it tells me my cores run at about 40 degrees ( which i am not worried about at all) but my cpu says it ranges from 65-75 degrees. BUT the real question is when i run prime 95 for a test my cores go up to 65 (okay) but my cpu temp drops to 35 degrees. is the cpu reader just off? should i worry about anything at all?
