The computer power supply fan is one of the more important cooling fans in a computer, and forms an integral part of the Power Supply Unit. It is still considered to be a primary cooling source for the entire computer, and this is a fact, which is ignored by many.
The power supply unit provides a reliable and steady source of power to all the different components within the system, and the failure or incapability of the PSU as it is called, to deliver the required power, leads to component damage, and with it, data corruption. The computer power supply fan helps keep temperatures down within the PSU, and this particular aspect, plays a major role in the smooth working and functioning of a computer.
Most new age Power Supply Units available in the market today, boast of more than one computer power supply fan, and a majority of the said fans, are ultra quiet in nature. The computer power supply fan is traditionally positioned at the rear of the PSU, and a majority of fans associated with Power Supply Units, make use of +12 V power to operate.
Keeping in line with changing times and technological advances, today’s PCs contain a range of additional cooling methods, like CPU cooling devices, auxiliary fans, etc, but this in no way undermines the role played by a computer power supply fan, in the overall cooling equation of a computer.
It is a matter of great interest for a regular PC user to know, that the standard size of a computer power supply fan is roughly 80 mm square, and the heart of the said fan, lies in its motor. The computer power supply fan comes in other sizes as well, and rates high on the list of PSU fans, in terms of the quantity of air it can move.
