my pc case gets pretty warm during the hot season since its on 24/7. So i added 2 fans side by side to the rear.

1 fan as intake 1 as exhaust.
The stock grille on the casing was cut to enable 100% free flow of air in and out of the casing.

The case is much cooler now.

But i need fans for my 2 hard disks as its kinda hot... Gonna add it later.
