We have a laptop that is getting to hot. It's a sony Sz series PCG-6N1L. The fan is running fine when I look at it. We have taken out out the heat sink on it and made sure that is was clean. We also put some CUP compound (white ones from raido shack ) on it. There was some pink ones on there which we cleaned and put that on there. I opend ot recheck again and every time I see that the cpu compound is milted under the heat sink insted of sticking to it. The entirie keyboard and the back area gets very hot.
