PC case fans

PC case fans

it is a type of fan that connects to the motherboards with the help of connectors into a fan header inside the motherboards.

It blows hot air outside so that system remains under control.

The fan speed can be changed as needed and is typically temperature controlled. A case fan, sometimes known as a system fan, is a component of a computer that is attached to the front or rear of the device’s chassis. Case fans aid in cooling down and expelling heated air from the case.

How many case fans are required

As you increase the number of case fans the efficiency will definitely be increased. But usually, two fans are enough. Two fans drop a maximum temperature of 2 to 3 degrees that is enough.

Any additional fans really provide any extra advantages. a good airflow from the case fans benefits the GPU and CPU’s own fans, so keep that in mind. In the case of a gaming pc where you need high power, you can connect six fans. Remember that it is an optional case and not necessarily needed.
