Who is the Responsible for active cooling on CPU?

The responsibility for active cooling on a CPU lies primarily with the cooling system, which typically includes a combination of heatsinks, fans, and sometimes liquid cooling solutions. The CPU itself generates heat during operation, and the cooling system is designed to dissipate this heat to maintain optimal performance and prevent overheating. Additionally, the motherboard may have built-in temperature sensors and fan controllers to regulate the cooling system's operation based on CPU temperature.
