Check Case Fan Size-

Check the Case –

Find empty spots where the fans can be installed. Every case has its own fan configuration. Try to choose the maximum number of fans and keep the system cool and better working always.

Fit Your Fan Properly-

You should fit your fan properly because of air mainly Travels through the fan in and out. If you change the direction of the fan, it can set the overall airflow. So, Must have a clear path to travel the air and pass through the system case fan. In case the vents are located upwards, the location of the fan should be placed facing in the above direction. Hot air tends to rise upwards. On the other hand, if the vents are located sidewards, they should be used for air intake and preventing the tissues. To get the best outcome, you should customize your own filters and enhance the overall life of your system.

Reduce Dust –

Talking about dust, you should make sure that your computer is always free from any kind of dust and small particles. Apart from cooling down the system, case fans must enhance the quality of air passed on to the system. The inbuilt filters must have a role play in filtering the air and reducing the accumulation of dust in the PC. You should make sure that you clean the filters at regular intervals to enhance airflow and overall cooling Power.

Positive Air Pressure vs. Negative Air Pressure

Air pressure is yet another important point of discussion while buying a computer cooling case. Either, a computer case can have a positive pressure or a negative pressure. In case of positive pressure, the fan pushes more air into the case rather than pulling out. Therefore, there is a huge amount of air pressure within the case.

On the other hand, negative air pressure is all about pulling out the air thereby creating a vacuum. In case of intake, CFM is Greater, using case fan having positive pressure would be better. On the other hand, if exhaust CFM is it more, using negative pressure would be the best option.
