Once you've picked a CPU, keeping it cool is top priority. Here is an easy guide on how to choose the best CPU cooler for your next build.
Compatibility
There are two different types of CPU coolers: traditional air coolers and liquid coolers.
Air coolers are more common because they're more affordable and easier to install. Liquid or AIO (all-in-one) coolers use pipes that carry coolant to the baseplate.
Liquid coolers perform better than air coolers, but air coolers are more reliable in the long term because there are fewer moving parts.
Make sure the cooler is compatible with the CPU, case, and motherboard. The CPU socket and motherboard are especially important. Check the cooler's spec sheet, it will list all of the detailed info.
The cooler should fit inside the case and not interfere with other components like RAM or the graphics card. Double-check the height and width of the cooler.
Performance
The best way to gauge a CPU cooler's performance is by looking at its TDP (Thermal Design Power) rating.
TDP measures the maximum amount of heat a CPU generates under general use. Some CPUs have a much lower TDP, and only a stock air cooler is needed.
But if you're dealing with a CPU with a TDP of 150W or higher, the cooler would need to match that output.
Fan speed, pump speed, and heat sink density are also important. Take a look at the number of heat pipes and fans, as well as the airflow design.
With AIO coolers, fan quality, radiator size, and tubing material matter. And you probably don't want your machine running loudly - so check for coolers designed for silent operation!
Installation
If this is your first time building a PC, installing a CPU cooler can be a bit daunting.
The cold plate of the cooler has to align perfectly with the CPU, and you need the right amount of thermal paste. Then you'll need to carefully screw the cooler into the motherboard.
For newbies, it's best to find a cooler with the easiest installation possible. Air coolers are perfect for this.
But maybe you want to cool to the next level. A custom water-cooled PC uses parts such as a reservoir, radiator, CPU block, and more to create a custom loop for cooling your CPU.
Keep in mind custom water-cooling takes a while and your build time will increase!
Wrapping Up
Whatever CPU cooler you choose, make sure it's compatible with the case, motherboard, and CPU. Leave room for the other parts!
TDP should be a major factor when selecting a cooler. Higher wattage calls for beefier coolers.
And if you're skeptical about what cooler to install, opt for the easiest one possible. Most of the time, all you need is something for general use.
