CPU is the central processing unit of a computer that is meant to execute all the circuitry instructions of a computer program. The input/output operations of a computer program, arithmetic, logic, and controlling tasks are all performed by the CPU.
According to Mark Galina: “ During normal operation, transistors inside a CPU convert electrical energy to thermal energy, and If an efficient path for that heat doesn’t exist, then the CPU will exceed its safe operating temperature.”
To deal with this issue, CPU coolers, and fans are designed so that the computer dissipates minimum heat and it works efficiently with a longer lifespan. These coolers provide a path for dissipated heat so that it does not exceed the safe operating temperature of a computer.
Working of CPU coolers:
- The CPU coolers absorb the released heat from the processor and redistribute it away from the hardware.
- The processor generates heat. This heat is distributed to a metallic lid named Integrated Heat Spreader (IHS). From IHS, heat is distributed to the base plate of the cooler.
- The water or air pipes are built to flow heat to the fan. The fan blows heat away from the cooler and the computer.
Difference between a CPU cooler and a fan :
The CPU fan is mounted on top of the CPU. This works as a regular fan and moves the hot air from the case and spreads it to the room, while the CPU cooler has a complex and effective system consisting of pipes and a base made up of aluminum or copper; within these pipes, a liquid is present to cool the hot ambient air and then blow it away from hardware.
Why CPU cooler is necessary?
Like every machine, the CPU works at only optimum temperature. Suppose the amount of heat exceeds the optimum temperature range provided for a computer. In that case, the performance of the CPU throttles, and it may shut down, deleting all of your important documents!
The CPU cooler is a savior.
- It cools the internal conditions
- Protects CPU from getting damaged
- Stops CPU from losing lifespan
Factors required while choosing a CPU cooler:
An ideal CPU cooler ensures minimum heat generation and maximum working speed of a computer. The features required for a cooler may vary with the type of PC being used.
For choosing the best CPU cooler, the following crucial factors should be kept in consideration that may help you make an informed decision :
1. Compatibility with the processor
The first and foremost factor to consider is compatibility. The CPU cooler should be compatible with your CPU socket and processor. The compatibility of the CPU cooler with your processor can be checked on the manufacturer’s website.
2. Compatibility of Size to Form Factor
The CPU cooler size should match your PC case’s scope. Select a low-profile CPU cooler if you have a small form factor PC case. On the other hand, if you have a giant PC case, you can go for a bigger CPU cooler.
3. Cooling Performance
A CPU cooler’s primary function is to maintain your processor’s optimum temperature. Therefore, cooling performance is a crucial factor to consider.
The cooling performance of a CPU cooler is measured in terms of its cooling capacity, expressed in TDP (Thermal Design Power). The higher the TDP, the better the cooling performance of the CPU cooler. Make sure to check the thermal performance of the cooler before purchasing it.
4. Minimal Noise Level
CPU coolers can be noisy, especially under heavy loads. A CPU cooler with a high noise level can be annoying and distracting, especially if you’re using your PC for long hours. Therefore, selecting a CPU cooler with a low noise level is essential.
Last but not least, the price is an essential factor to consider. CPU coolers are available at different prices, and you need to select the one that fits your budget. However, it’s important to note that a higher-priced CPU cooler doesn’t necessarily mean better performance.
Types of CPU coolers :
CPU coolers are composed of hundreds of tiny parts and are available in numerous sizes, speeds, and noises. There are two types of CPU coolers; liquid-based and air-based.
i. Air based:
Air-based coolers are inexpensive, and their replacement parts are readily available, so they are ideal for average PC users. The heat generated by the CPU is drawn through a heat sink, which is a place for heat to sink into.
The heat first flows from the top of the CPU into the attacked metal plate then runs up the pipes to a more significant metal case, and finally, the air is blown away from the PC.
The other type is the liquid type which is famous for high-end builds. Water or glycol is used as a medium for liquid cooling. The water block absorbs the heat rather than a heat sink.
The heat from the water block is pumped into a radiator, which uses an air current to dissipate the heat. The now-cool water travels back to the water block to repeat the process.
iii. Passive Coolers
Passive coolers are CPU cooler types that do not use fans or liquid to dissipate heat. They rely on passive cooling. Passive CPU coolers (also known as heat sinks) use only a metal block to dissipate the heat generated by the CPU.
They have no moving parts, making them completely silent and highly reliable. Passive coolers are affordable, easy to install, and require no maintenance. However, they are less efficient than air, liquid, or thermoelectric coolers. Moreover, they may require additional airflow to function correctly.
iv. Thermoelectric CPU Coolers
Thermoelectric CPU coolers, also known as Peltier coolers, use a thermoelectric module to cool the CPU. The module generates a temperature difference between two plates. One plate is attached to the CPU, while a fan or liquid cools the other.
Thermoelectric coolers are highly efficient and can achieve shallow temperatures. They are also quiet and have a long lifespan. However, they are the most expensive type of CPU cooler. Moreover, they can generate a lot of heat dissipated by a fan or liquid.

How to choose between Air based and Liquid-based CPU coolers?
Both liquid-based and air-based coolers have pros and cons. The following factors will help you choose the best CPU cooler.
Components of CPU cooling:
Some CPU coolers work as passive heat sinks, but most of them are active devices, and proper complex systems are provided for radiating heat and improving the operating speed of a CPU.
At least one fan is provided in every CPU to draw hot air from inside the computer and inhibit the entry of warm air from outside. The power supply unit, CPU GPU, and hard disk drive use one or more fans to expel waste heat.
From early supercomputers to high-performance computers, water-cooling systems have always played a crucial role in the maintenance of computer systems. They include a water block, pump, and heat exchanger. All the components are located within the computer and serve to cool hot air.
iii. 3. Phase change:
Phase change coolers can provide extreme cooling up to -150 degrees. These use scarce and complicated technology to change a gas mixture to a liquid and are only employed by frequently over-locked computers.
Installation and Maintenance of a CPU Cooler:
Installing a CPU cooler can be daunting, but it can be done quickly with the right tools and knowledge. Here is a step-by-step guide to install a CPU Cooler easily.
Maintenance tips for a CPU COOLER:
