My main computer is an hp zv5000 - it uses two heat pipes with heat sinks and two fans to cool the processor. Through use, those heat sinks (copper?) and pipes collect quite a bit of dust reducing the machine's cooling capacity.
If you don't have this specific machine, not to worry. Just use some common sense as the basic idea is the same.

Have fun.
