Fan rpm meaning
WebRPM is Revolutions per minute .. a measure of how fast a fan spins. While it’s true that higher RPMs mean a bit more noise, the question you should be asking is what is the DB (decibel) rate of the fan at different speeds and at different distances from the fan. RPM can tell you a little, but not what you are asking. 2 Harry WebMar 17, 2024 · PWM fans are 4-pin fans, where the fourth wire sends a PWM signal to the fan motor.
