I am not familiar with the liquid cooled systems. If you have one of those refer to their manual for routine maintenance. Otherwise if it is a fan cooled version: This typically requires more than just vacuuming the outside. Typically you have to remove the heatsink and fan, and use a brush or q-tips to ferret out the various dustbunnies in the nooks and crannies that are near the CPU. Most heatsinks have retainers that hook down to the socket. look carefully at how the hooks engage and look for a lever to release them. Open ONLY that lever. Do not open the wire lever under the socket, it holds the cpu to the socket. You will need to be careful not to pull the CPU from its socket, because if you do that without releasing the socket, the pins will bend (if it is a pinned CPU) if it is BGA, you risk "smearing" the balls. So that requires care. Its not difficult, just don't "rip" the heat sink off, but pull it slowly from the grip of the adhesive bond of the heatsink compound. Once it is off, remove the fan, typically 4 screws, then using a small tool, like a lady's finger care orange stick to ferret out all the hair balls and dustbunnies. You can also wash the heatsink in warm soapy water, it's aluminum, just like an aluminum cooking pot. Clean the top of the CPU with a static free rag and a small amount of alcohol to ensure a good contact area of the heatsink compound. To replace the heatsink, re-attach the fan, noting the lenght of cord to connect to the motherboard for the fan, so orient it as required, Then add a single drop of heatsink compound at the center of the CPU. Just a single drop. Then sort of "wiggle" the heatsink down to spread the compound. Close the retainer as you had to do to remove the heatsink. That's it. Your cpu should be cooling as designed.
