Improper installation woes.

Specs: Windows XP
I removed my fan and heatsink from an ASUS PTGD1-LA. Separated the components to clean them. reinstalled. Fan runs at normal speed for a minute or two then revs up for a long time before going back to slower speed. There is a row of diodes on two sides of the cpu. The HS is shorter on two sides. Does the HS need to be right on top of the diodes or is the space for cooling? Will too much compound cause a cpu to run hot?

"Will too much compound cause a cpu to run hot?"

Definitely! All that's needed is a tiny dab or a thin line of paste depending on the CPU. If you layered it on like frosting a cake, it becomes an insulator & holds the heat in rather than transferring it into the heatsink.

Find your CPU on this list, then read the application instructions:
