Fan speed是什么意思

"Fan speed" refers to the rate at which a fan rotates or the number of revolutions per minute (RPM) at which a fan operates. It is a measure of how quickly the fan blades turn, which affects the amount of airflow the fan produces.

In electronics and computing, fan speed is often used to regulate the temperature of components such as the CPU, GPU, or other heat-generating parts. The speed of the fans can be adjusted automatically by the system's BIOS or operating system, or manually by the user, depending on the cooling needs and the preference for noise levels.

In HVAC (Heating, Ventilation, and Air Conditioning) systems, fan speed can also refer to the speed at which the blower motor operates, which affects the rate at which air is circulated throughout a room or building.
