Computer cooling systems are essential for maintaining the optimal temperature of a computer's components, such as the CPU and GPU. When these parts work hard, they generate heat, which can lead to overheating and damage. Cooling systems help dissipate this heat, ensuring that the computer runs efficiently and lasts longer. There are two main types of cooling systems: air cooling and liquid cooling. Air cooling uses fans and heat sinks to move hot air away from components, while liquid cooling circulates coolant through tubes to absorb and transfer heat. Both methods are effective, but liquid cooling often provides better performance for high-end systems.
