It's recommended to periodically clean the CPU cooler using compressed air or a soft brush to remove any buildup.

Additionally, some CPU coolers feature removable fan blades or detachable heatsinks, making it easier to clean or replace individual components. It's essential to consult the manufacturer's instructions for specific cleaning and maintenance guidelines to avoid damaging the cooler.

3. CPU IHS

The CPU Integrated Heat Spreader (IHS) is a metal lid that covers the CPU die, providing thermal conductivity, protection, and a flat surface for the CPU cooler. The IHS is typically made of a material such as nickel-plated copper or aluminum and is soldered or glued to the CPU package.

The IHS acts as a buffer between the delicate CPU die and the cooler, ensuring even distribution of thermal paste and minimizing the risk of damage during cooler installation. It also helps to spread heat evenly across the CPU surface, improving cooling efficiency and preventing hotspots.

Some enthusiasts and overclockers opt to remove the CPU IHS in pursuit of better thermal performance. This technique, known as delidding, involves carefully removing the IHS to apply high-performance thermal compounds directly to the CPU die. Delidding, however, requires caution and specific tools to avoid damaging the CPU and voiding the warranty.

3.1 Risks and Considerations of Delidding

Delidding a CPU is an advanced technique that carries some risks and considerations. Removing the IHS requires precision and the use of specialized tools, such as a delidding tool or razor blade. Mishandling the process can result in permanent damage to the CPU or voiding the warranty.

When delidding a CPU, enthusiasts often aim to replace the stock thermal compound with higher-quality thermal paste or liquid metal. While this can improve thermal performance, liquid metal compounds are conductive and can pose risks if they come into contact with other components on the motherboard. To mitigate this risk, careful application and isolation techniques are required to prevent short circuits.

It's important to note that delidding a CPU is generally not recommended for the average user or those unfamiliar with advanced overclocking techniques. If done incorrectly, it can permanently damage the CPU or lead to poor cooling performance.
