Keeping your PC cool is critical for maintaining its performance and lifespan. PC cooling systems typically involve a heatsink and fan combination. The heatsink, a metal block, absorbs heat from the CPU or other components. The fan then blows air across the heatsink fins, dissipating the heat away from the PC's interior. Some high-performance systems use liquid cooling, which circulates cool liquid to absorb heat and then radiates it out of the PC through a radiator and fans. There are even quieter, passive cooling options that rely solely on heatsinks for low-power components.W
