How Does a CPU Cooler Work?

Nowadays, many advanced processors are incorporated with a temperature sensor to ensure that the processor does not overheat. However, sometimes, the temperature crosses the threshold, which might affect the performance of the processor.

A CPU cooler is ideally designed to move the heat away in order to maintain an optimal temperature for the processor. Generally, the heat pipes of a CPU cooler are manufactured from copper, which are filled with liquid. This liquid vaporizes when heated. The vapors travel to the cooler and condense, which releases the excessive heat. In addition to a fan, there is a large area of cooling fins to increase the cooling effect.

When Would a CPU Cooler Come in Handy?

Although you get CPU coolers included with the processor that are reliable for the majority of the cases, not all of them are capable of handling extreme performance. Therefore, in order to push the boundaries of your processor, you might need to upgrade your CPU cooler.

PC Overclocking

In case you want to overclock your processor and intend to make the components of the system run harder and faster, then you should definitely incorporate a high-end CPU cooler. Stock coolers that come with the processor are not reliable enough to withstand the amount of heat generated by the operation.
