13 best CPU coolers

Review of the best according to the editorial board. On the selection criteria. This material is subjective and does not constitute advertising and does not serve as a purchase guide. Before buying, you need to consult with a specialist.

The processor heats up intensively during operation. This is due to the laws of physics and there is no way to get around them. Coolers, in turn, are designed to cool the processor to a temperature at which it will function normally. We have compiled a rating of the best coolers that are suitable for use with almost any processor – from a simple Celeron for an office 'typewriter' to a high-performance Intel Core i7-7700K, which remains one of the best gaming chips to this day.

How to choose a CPU cooler

A processor cooler must be chosen carefully. Otherwise, he will not cope with his 'duties'. Overheating of the processor, in turn, leads to a drop in performance, shutdown of the computer or damage to the chip itself.

Active, passive and liquid cooling

Cooling can be organized in one of three types – active, passive and liquid.

An active cooling system involves the use of a radiator and fan. The first is installed on the processor. The plumage of the radiator is heated by the 'chip', after which it is cooled by air currents. The efficiency of the active cooling system depends on the materials from which the heat pipes are made, as well as on the fan performance.

So, the most effective copper heat-water tubes with copper or aluminum plumage. But exclusively aluminum heatsinks are suitable for cooling only old or budget processors like Celeron or Pentium lines.

The disadvantage of an active cooling system is that it needs a constant flow of 'cool' air inside the case. Otherwise, other components on the motherboard may overheat. Therefore, the system unit must be installed so that air circulates freely around it.

In addition, the efficiency of active cooling decreases when the radiator becomes clogged with dust.

The liquid cooling system is structurally similar to the active one. Only instead of a radiator, a contact plate and special tubes with a heat-transfer fluid (often ordinary water) are used. The fans are placed in a separate unit, which is exposed outside the system unit. Thanks to this, there are no special requirements for the installation of the system unit, and the performance of the cooling system does not decrease over time.

The disadvantage of a liquid cooling system is that it is expensive.

Passive cooling consists only of a heatsink. The heat from the processor is dissipated naturally through convection inside the system unit. The performance of such a cooling system leaves much to be desired, so it is used exclusively with slightly heated chips – old or mobile, including laptop or ultrabook.

When choosing the type of cooling system, you should be guided by the purpose of the computer:

  1. An office 'typewriter' with an old or low-power processor – a passive heatsink will do;

  2. 'Normal' or 'gaming' computer – active cooling;

  3. Gaming computer with top-end components – liquid cooling.

What to look for when choosing a cooler

The main criteria when choosing a cooler are the compatible socket and power dissipation.

  1. Since processors differ not only in performance but also in size, it is important to consider socket and cooler compatibility. Socket – the size and form factor of the chip itself, as well as the placement of the cooling system mounts on the motherboard. If it is not compatible with the cooler, you will not be able to install the latter. You can find out which socket is in use from the specifications of the processor and motherboard, as well as through the AIDA64 program or similar.

  2. Power Dissipation – Cooling system performance. It shows how much heat can be removed by the cooler. The power dissipation must be greater than the heat dissipation (TDP) of the processor. Both of these parameters are measured in watts, so it is not difficult to compare them.

The rest of the parameters are optional and do not really matter when choosing a cooler.


The quality of the materials used, the durability of the cooler and additional functions of the cooling system depend on the manufacturer. Therefore, it is advisable to choose devices from trusted companies.

We have included cooling systems from renowned manufacturers such as Noctua, Zalman, Thermalright, Deepcool, Prolimatech and Arctic Cooling in our rating.
