Computer hardware always generates some amount of heat as a result of power consumption. Devices like Integrated Circuits i.e. CPU, GPU, VGA cards, etc are more prone to generating heat while running the computer. Due to heavy and continuous workload, these devices overheat. To protect these components from heat damage, computers require a good computer cooling system to maintain operational temperature.

The computer Cooling Mechanism helps to remove the spare amount of heat generated in the system so that the device performs excellently. Your computer may take temporary or permanent damages if you don’t deploy a proper cooling system in it.

All the CPUs and some advanced GPUs and motherboards come with a heat sink on their top. It is generally a large metal surface and draws out excessive heat from them. Thermal pastes or adhesives help to dissipate heat away from the CPU to the heat sink.

There are a number of ways to keep the processor cool in your computer but the major cooling mechanisms that manufacturers avail are air cooling and liquid cooling.

Computer Cooling: Air Cooling

The heat sink attaches to a CPU air cooler fan that forces air in the heat sink. The hot air then expands and blows away out of the case. The cooler then pulls in cool air to balance the air pressure maintaining a cool temperature.

Liquid Cooling

Air cooling is the traditional method and some of the computers these days face issues due to the inefficacy of air cooling. Liquid cooling PCs are more overclocked and dissipate more heat as compared to air coolers.

In water cooled PCs, a pump circulates cool water to the radiator and absorbs heat from the radiator. Liquid immersion cooling is a rare technique in which the computer or its components immerses in thermally conductive liquids like oil.

Best Computer Cooling Products

Below are some of the best CPU coolers you can buy now.

1.Noctua NH-D15

Featuring 140 mm dual fans and fine-tuned six heat pipes, Noctua NH-D15 offers greater air circulation. The Secufirm 2 mounting kit is compatible with a large variety of Intel cores like LGA 1150-2066, FM 1-2+, etc. The recessed lower ends make it easy to install on high-end RAM modules. The noise adapter lowers the noise by 2x for quieter operation.

The Noctua cooler is on the high-end than other air coolers but is definitely the best in the business.

2. Corsair H150i Pro

The Corsair H150i Pro all-in-one liquid cooler 360 mm radiator and three PWM fans powered by magnetic levitation that reduce noise and enhance performance. It is compatible with Intel LGA 1150-2066, AMD1-4, etc. Using Corsair iCUE software, you can adjust the speed of fans, RGB lighting, and liquid temperatures.

You should consider buying this cooler for a liquid cooled gaming PC and save your PC from overheating due to intense gaming sessions.


Having a good computer cooling system saves your computer from sudden shutting down, lagging, or permanent damaging of the processors. Most of the computers already have a PC cooling system integrated into them and if not you can buy one and fix the problem.
