What make & model are your laptop?
Before you do anything intensive (e.g pulling the thing apart) I'd suggest googling, for example, "Dell Studio 1558" or whatever it is.
Some laptops have fundamental flaws in the way they're put together in terms of heat dissipation... so knowing what you're up against before you
start is important.
For example, my Dell Studio 1558 was overheating. The reason, however, is because the heatsink that covers the CPU, GPU and memory had .1mm height
discrepancy (that is, the heatsink for the CPU was flush, but the heatsink for the GPU was .1mm higher) and nothing to compensate.
I bought a .1mm copper shim to put between the two, applied new thermal paste (including both sides of the shim), whacked the thing back together, and
BAM! Temps dropped from ~90c (which is the shutdown temp, as a safety mechanism) down to about 40. Much better. I haven't had a shutdown since.
So... knowing what you're up against is an important place to start.
