This setup will cool the hard drives, cpu, video cards, ram, etc.
I have an 80mm fan at the front sucking air in, and 2x 80mm fans on the side sucking air in, and 80mm fan blowing on the HDD and an 80mm fan thats blowing air out at the back, system temp is usually 25-35C. I dont have any 120mm fan spaces so i cant fit one!
