The Different Types of CPU Heatsinks

When it comes to cooling your CPU, a heatsink is an essential component that helps dissipate the heat your processor generates. Heatsinks come in different types and sizes, and choosing the right one for your CPU can significantly affect performance and temperature management. In this article, we'll look at the different types of CPU heatsinks available and how they work.

Air-Cooled Heatsinks

Air-cooled heatsinks are the most common type of CPU heatsinks used today. They use heat pipes, fins, and fans to draw heat away from the CPU and dissipate it into the surrounding air. Air-cooled heatsinks come in different sizes and shapes and can be either active (with a fan) or passive (without a fan).

Air CPU heatsink

Active Air-Cooled Heatsinks

Active air-cooled heatsinks, also known as fan-cooled heatsinks, use a fan to blow air over the heatsink's fins, increasing airflow and improving heat dissipation. Active air-cooled heatsinks are generally more efficient than passive ones, but they can be noisier due to the fan.

Passive Air-Cooled Heatsinks

Passive air-cooled heatsinks, also known as fanless heatsinks, do not have a fan and rely solely on natural convection to dissipate heat. Passive air-cooled heatsinks are generally quieter than active heatsinks. Still, they are less efficient at cooling and may not be suitable for high-performance CPUs.

Liquid-Cooled Heatsinks

Liquid-cooled heatsinks, also known as water-cooled heatsinks, use a liquid coolant, such as water or a water-based solution, to absorb heat from the CPU and transport it to a radiator, where the heat is dissipated into the air. Liquid-cooled heatsinks can be either closed-loop (all-in-one) or custom.

Closed-Loop Liquid-Cooled Heatsinks

Closed-loop liquid-cooled heatsinks, also known as all-in-one (AIO) liquid coolers, come pre-filled and pre-assembled, making them easy to install and maintain. They consist of a pump, a water block, and a radiator connected by tubes. They are generally more efficient than air-cooled heatsinks.

Custom Liquid-Cooled Heatsinks

Custom liquid-cooled heatsinks, also known as open-loop or custom-loop liquid coolers, are fully customizable and require more expertise to install and maintain. They consist of separate components, such as a pump, reservoir, water blocks, tubes, and radiator, which can be configured to your specific needs.

Phase-Change Heatsinks

Phase-change heatsinks use a refrigerant, such as Freon or ammonia, to transfer heat from the CPU to a condenser, where the heat is dissipated into the air. Phase-change heatsinks can achieve extremely low temperatures, making them ideal for overclocking and high-performance computing. However, they are expensive, noisy, and require significant power to operate.


Choosing the right CPU heatsink depends on your specific needs and requirements. Air-cooled heatsinks are generally the most common and cost-effective option. In contrast, liquid-cooled heatsinks offer better cooling performance and customization options. Phase-change heatsinks are best suited for extreme overclocking and high-performance computing. When considering a custom CPU heatsink, it is important to work with a reputable manufacturer that can help you design and optimize a heatsink for your specific application.

In summary, understanding the different types of CPU heatsinks available can help you make an informed decision about cooling your CPU. Whether you opt for an air-cooled, liquid-cooled, or phase-change heatsink, it is essential to consider factors such as efficiency, noise level, and cost before making a final decision. It is also crucial to ensure that your heatsink is compatible with your CPU's socket and provides sufficient clearance for other components, such as RAM and graphics cards.

When it comes to custom CPU heatsinks, working with a reputable manufacturer is crucial. A custom heatsink can be designed and optimized to meet your needs, such as reducing noise levels or improving cooling performance. A manufacturer with expertise in thermal management can help you select the right materials and manufacturing processes to ensure optimal performance and longevity.
