How to install Heat Sink/Fan
Today’s processors are running quite hot. Advancements are being made to make them run cooler at higher speeds, but the importance of a high quality heat sink and fan cannot be overstated. PCs that are not properly cooled can be quite unstable, or at its worse, it may not even boot properly.
It used to be that you could attach a heat sink and fan to your processor directly and not worry about it. Today, though, processors run too hot to do this and expect a reliable PC. One must use heat sink compound to seal the gap between the heat sink and the top of the processor.
Some heat sinks have a rubber heat pad on the bottom of them. In these cases, you don’t really need to use heat sink compound because the rubber pad will create the seal. It should be kept in mind, though, that if you are using a heat sink which has been used before and had a heat pad, that heat pad is now likely melted in the spot where the previous processor contacted it. In these cases, you cannot use the heat pad again as it will be ineffective. Instead, you need to clean the old rubber pad off of the heat sink using a non-abrasive cleaning compound.
