What is a CPU Cooler?

Before we get into the details of how to check your CPU cooler, let’s first understand what it is and how it works. As mentioned earlier, a CPU cooler is responsible for keeping your processor from overheating. It consists of a heatsink, fan(s), and thermal paste. The heatsink is a metal structure with fins that absorb heat from the CPU and transfer it to the surrounding air. The fan(s) then blow air over the heatsink to dissipate the heat. And finally, the thermal paste acts as a conductive material between the CPU and the heatsink, ensuring efficient heat transfer.

There are two main types of CPU coolers: air coolers and liquid coolers. Air coolers use the combination of a heatsink and fan(s) to cool the CPU, while liquid coolers use a pump to circulate coolant through a radiator, which then cools the liquid before it is pumped back to the CPU. Both types have their pros and cons, but they ultimately serve the same purpose of keeping your CPU at safe temperatures.
