These fans are designed for force-air cooling of electronic devices. The fan will generate cool air by spinning at variable rates, thus protecting against thermal variances that will undoubtedly harm the devices and will prevent premature failure. Computers, electronic components, and machines today have increased in power consumption resulting in an increase in the amount of heat produced by the components in computers. In order to function effectively and to avoid overheating, malfunction, instability and breakdown leading to a shorter lifespan, these components need to be kept within some specific temperature range. An AC (alternating current) cooling fan operates by blowing air along the axis of the fan. Also, our fans are used in homes and offices in large scale.
