Today while doing some light gaming on my laptop (i7 3632QM, HD4000, 8GB Ram, Windows 7 Pro) I noticed the area around the CPU was hot. I downloaded a cpu temperature monitor. It said my CPU was 80-75C, and 3 of 4 cores had 75% load on them. I figured that this was about normal, but just to confirm this I looked it up and the results agreed with my assumption. So then I fired up Prime95. After 30 seconds all 4 cores were topping high 90s-100C. After about three minutes system crash. I had previously opened up the laptop and reapplied thermal paste and dusted should I do this again? Or is this normal?
