What is a CPU Heat sink Fan? How to choose the right heat sink

Every CPU has something in common: they get very hot when they are working. That's why we have these coolers, to keep the CPU running cool instead of immediately cooking itself.   But how do you know what kind of cooler you want? That's what we're going to talk about.   Heat sinks, also known as heat sink fans (HSFs) or coolers, come in various shapes and sizes. The purpose of each cooler is to draw heat away from the CPU and dissipate it. The CPU needs to be cooled because if it gets too hot, it will blow itself up, although modern CPUs are smart enough to slow down or even shut down completely before they get too hot.   In an air cooler like this one, the heatsink is in contact with the CPU through heat-conducting metal and heat pipes that suck heat away from the CPU and dissipate it over a wide area while blowing it away with a fan.   If you are wondering if heat pipes do anything, we can assure you that they serve a purpose. They are hollow inside and contain att...
