The Best CPU Coolers In The World 2020

A Comprehensive CPU Coolers Buyers Guide

For many PC gamers, the stock cooling options that come bundled with their store-bought PC are good enough, especially if you’re not playing graphically-intensive games on a regular basis. Even if you build your own PC, the included fans and thermal grease that comes with your CPU is more than adequate for most setups. However, for a particular subset of PC gamers, the stock cooling options are lacking in power. For example, if you’re planning on overclocking your PC or cranking up the graphics to their maximum setting and playing for hours at a time, you need a better cooling solution. Knowing the ins and outs of the various aftermarket CPU coolers can help you choose one that is perfect for your needs.


What Is a CPU Cooler?

Simply put, a CPU cooler is a device designed to cool down your CPU. Because a CPU acts as the “brain” of your computer, it can reach scorching hot temperatures, especially during instances of heavy graphical load such as playing a modern PC game. When a CPU reaches temperatures of around 85 degrees, irreversible damage can occur, with the possibility of even a fire starting instead of your PC case! By directly cooling down your CPU, a CPU cooler is an invaluable hardware component, and as such, you’ll always find one within every modern PC. If you need a bit more cooling power, there are three primary types of CPU aftermarket coolers available: air, water and liquid.

An air-based CPU cooler is a fan that you install directly on top of the CPU, connected to it by a cable. When the CPU starts to heat up, the fan will kick in an attempt to bring the temperature down. The stronger the fan, the more load you can place on your CPU. Keep in mind that an air-based CPU cooler can only cool a CPU down so much, typically around 15 to 20 degrees.

It is possible to place such a heavy load on your CPU that an air-based cooler isn’t cut out for the job, like when you’re overclocking your CPU, and this is where water cooling comes in. In laymen’s terms, a water-based CPU cooler uses a series of tubes to transfer water to your CPU block, absorb the heat and then move the heated water away from the CPU. While most water-based CPU coolers only use distilled water, there are some liquid-based coolers which use stronger liquids, such as antifreeze solutions. With a water- or liquid-based CPU cooler, it’s possible to keep your PC at low temperatures even when running multiple PC games at one time or overclocking your CPU to an extremely high voltage.


Who Are CPU Coolers For?

In general, your average PC user will have no need for an aftermarket CPU cooler, as the stock options that come with most CPUs and PCs are fine for your basic computing tasks. Even the majority of PC gamers won’t need an aftermarket CPU cooler, provided they don’t play games for hours at a time and keep their PC out of the sun. Aftermarket CPU coolers are primarily for two types of PC users: hardcore PC gamers and overclocking enthusiasts.

The basic premise behind overclocking is to take stock hardware, such as a CPU, and force it to output more power beyond what the manufacturer designates. By doing this, you’re causing your CPU to generate much more heat than normal, which is why an aftermarket CPU cooler is essential. If you try overclocking on a stock cooler, you’re going to end up with a fried CPU.

As stated previously in this buying guide, most gamers won’t have any need for aftermarket CPU cooling systems. However, if you’re hardcore about your games and are the type of gamer to set your display settings to maximum and game for hours at a time, an aftermarket CPU cooler will help ensure that your CPU won’t overheat.


Are There Any Disadvantages To CPU Coolers?

While having an aftermarket CPU cooler provides a lot of advantages, there are two small disadvantages that buyers need to take note of when purchasing.

The first is that some air-based CPU coolers can increase the sound emanating from your computer, especially when the CPU is at maximum load. In a worst case scenario, an aftermarket air-based CPU cooler can sound similar to a jet engine when it’s at full power, which can not only break immersion when gaming but potentially annoy those around you. To counteract this, look to purchase an air-based CPU cooler with a large fan, as larger fans run at a lower RPM than smaller ones, thus keeping the noise of your air-based CPU cooler at a minimum.

The other disadvantage of a CPU cooler is that in most cases, they take up a considerable amount of space in your PC case. Whether you’re using an air- or liquid-based CPU cooler, you’re going to need an average-to-large PC case to accommodate these setups. In general, coolers taller than 160mm will not fit in an average-sized PC case. Some gamers with limited case space will need to make sacrifices when adding a CPU cooler; for example, adding a CPU cooler to your rig could stop you from adding hardware like a second graphics card due to space limitations. Ensure that you have enough room for both your CPU cooler and any future hardware additions before purchasing and installing one.


What Else Should I Keep In Mind When Buying a CPU Cooler?

One of the best parts about purchasing a CPU cooler is that, unlike other hardware components, you likely won’t need to upgrade it anytime soon. Both air- and liquid-based CPU coolers are compatible with a broad range of motherboard and CPU types, meaning that it’s one of the few pieces you can reuse when building a new PC. With this in mind, sometimes it’s better to spend a bit more and buy a high-end CPU cooler because you’ll potentially get a decade’s worth of use out of it.

If you’re using a liquid-based CPU cooler, it’s imperative that you clean it out every few months, especially if you’re using any liquid that isn’t water. It’s possible for fluid to harden in the tubes, which can cause blockages and leaks without routine cleaning.
