How To Install Fans In A Gaming PC

Most cases are built with a specific airflow direction, usually front to back and bottom to top. That implies your intake fans should mount on the front of the case or the bottom if you have a multi-fan arrangement or blocked the front mounting brackets.

Exhaust fans are located in the back or on the vehicle’s roof. Exhaust fans should not be mounted on the bottom of the case; because hot air rises, a bottom-firing exhaust fan will be operating against the laws of physics by discharging somewhat cooler air rather than warmer air.

The direction of intake and exhaust should be front-to-back and bottom-to-top. Depending on the arrangement, side-mounted fans might be intake or exhaust fans when you go through all these things and explore them. Then open the case and place the fan in the required spot and tighten the screws with the help of screwdrivers. When you are done with the installation, enjoy the performance of your gaming pc.
