How to Choose a CPU Cooler?

installing a computer fan

As you can see there is an excellent range of CPU coolers available for gaming and high-quality computer rigs. But how do you know which one to choose? This can be a daunting task and it can have an impact on the overall performance of your computer.

This is not something you should rush into – choosing the best CPU cooler requires forethought and planning. As a bare minimum, you should already have in mind (or already purchased) the PC tower you intend to use, and the processor the cooler will fit on.

Without these items, you are buying in the dark and could potentially buy a CPU cooler that isn’t compatible. Also, you should have a general idea of the other components like a GPU, and RAM, so you know exactly how much space you have around the motherboard. To help, we have created a simple buying guide with considerations you should make before purchasing a CPU cooler.

Liquid Cooling vs Air Cooling - Which is Better?

First, it is important to understand the main two types of CPU cooler – liquid and air CPU coolers. These two types of coolers perform the same function. But they do so in a different manner, and both methods have pros and cons.

Liquid Cooling

Liquid CPU coolers transfer heat from the CPU into the water contained within a special tubing. The heated water travels to a radiator and is cooled. Once cooled, the water is recirculated back to the CPU for the process to start again. This is also known as a closed-loop liquid CPU cooler.

Liquid CPU cooling is more efficient than air cooling. This is because water is a better transferal method for heat, than air. Also, liquid CPU coolers are usually much quieter as there is often no noisy fan. A liquid cooling system is suitable for a gaming PC rig where performance is key.

On the downside, there is always a risk when using a liquid CPU cooler. What happens if water leaks from the tubes or radiator? Although this will rarely happen, it could potentially be catastrophic.

Air Cooling

Air cooling CPU systems are much simpler and require less space within your computer tower. As with a liquid cooler, a heatsink plate is placed on the CPU which is then connected to a fan.

The heat travels through various pipes and heatsink plates and is eventually dispersed away from the CPU via the attached fan. CPU air coolers usually have a much smaller footprint. However, they are also much louder due to the revolutions of the fan.

Also, air cooling systems are generally less efficient than liquid coolers. Air CPU coolers still provide excellent cooling and are fit for the purpose. But if you want maximum cooling and ultimate efficiency, a liquid cooler is a way to go.

What to Look for When Choosing a CPU Cooler?

Now that you understand more about the main types of CPU coolers, we can look at the main considerations you must make before buying one. As stated above, before getting to this stage, ensure you have a firm idea of the tower, motherboard, and other components you intend to use.

CPU Cooler Type

fixing the motherboard

Firstly, consider which type of CPU cooler you want. We have discussed the pros and cons of the different kinds given above. Liquid coolers are more efficient and much quieter. However, they require much more dispersed space and may pose a potential danger.

On the flip side, air coolers often take up much less space directly above your CPU. As a result, they are also much easier to install. However, the attached fan makes them louder, and they do not cool as efficiently as liquid coolers.

Think about the differences, and consider which CPU type you feel would be the better option for you. Also, take into consideration your technical skills in installing components.

Overall Size and Dimensions

It is also vital to have a clear idea of the overall footprint of the CPU cooler and its associated systems. Usually, an air CPU cooler has a heatsink and an attached fan that sit directly above the CPU. Liquid coolers, however, have a heatsink system, and a myriad of tubes that connect to a radiator and must be placed on the backplate of the tower.

You must therefore look at the immediate space you have surrounding your CPU on the motherboard. For example, will the CPU get in the way? Or will any other components like an HDD and associated cables create a barrier? Ensure that you have sufficient space surrounding your CPU for the cooler to fit.

Next, for liquid coolers, you must then assess if you have enough space for the radiator and tubing. This may simply require you to have an effective cabling system and use cable ties to maximize available space.


Next, you must look at the compatibility of the CPU cooler. Different CPU coolers may be compatible with different CPU sockets on your motherboard. This is vital to understand as you could end up purchasing a CPU cooler that you can’t even use with the processor you have.

In most instances, you will use either an Intel or AMD processor. These are considered the best quality processor manufacturer available. As a result, this narrows the compatibility considerably. However, different Intel and AMD processors still use a wide range of processor sockets including Intel 1200, 1150, 1151, 2011, and 2066 AMD, AM4, AM3, and AM2.

When choosing a CPU cooler, it should clearly state which processor sockets it is compatible with – double-check this to avoid disappointment.


Also, some people also value the aesthetics of a CPU cooler. In today’s modern world, we can create amazing custom computer rigs complete with LED lighting that look superb. Having a great looking CPU cooler may therefore be highly important.

If you have a fully-enclosed computer tower with no transparent panels, how the CPU looks may be of no concern. However, if you have an exposed side panel or transparent panels, you may want the cooler to fit in with the style of the rest of your components.

If style and aesthetics are important, we advise looking at photos on the web of the different coolers when they are installed. This should give you a clear idea of how they will look, and how they will fit in with your computer style.

Noise Levels

Noise levels are also important for some people. This depends on your personal preference and your tolerance for noise. If you don’t mind high noise levels from the CPU cooling unit, an air cooling solution may be a suitable choice.

However, if you want a CPU that runs quietly but still effectively cool, a liquid CPU cooling system is the best choice.

What Do You Use Your Computer For?

Finally, you must look at what you generally use your computer for. This will greatly dictate what CPU cooling system you need (if any). Remember that most basic computer systems will have a basic CPU cooler installed – the coolers in this list are aftermarket products that you would purchase to upgrade your computer.

Do you use your computer simply for emails, and general data entry? If so, an ultra-powerful CPU cooler should not be necessary. However, if you use your computer for intense graphic design, movie editing, or you are a PC gamer upgrading your stock CPU is a must. As a result, you would greatly benefit from purchasing a high-power CPU cooler.


Don’t underestimate the importance of a CPU cooler. These advanced devices can make a great difference in the performance of your computer. Also, they can help improve the longevity of your components and prevent them from burning out or overheating.

Anyone of the above 10 best CPU cooler options would make an excellent choice for a computer gaming rig, or a computer for graphic design and 3D modelling. Overall, we recommend the Cooler Master Hyper 212 CPU cooler.

This model contains copper heat pipes and a 120mm RGB fan, which can synchronise with your existing motherboard architecture or can be manually assigned using the included controller. Additionally, the CPU’s aluminium fins have lateral grooves to further induce thermal conductivity.
