Cooling fan - Speed control systems
Dec 30 , 2021
Brushless DC (BLDC) fans are the most common type used to cool electronic equipment. Many cooling fans now have additional functions which provide greater control the fan speed and operation, thus improving the system performance. Having a fan run constantly even when maximum cooling is not required, does not result in an efficient system and can reduce the service life of a fan. If the average sp...
