Custom Case Cooling
I'm currently putting together a custom projector trolley thing. I've got a trolley with a lockable cabinet in which the PC will be. It will get pretty hot inside so I'm going to drill some vents and install some case fans.
But what's best? Two fans blowing air out with some vents for air to get in or a fan blowing in and a fan blowing out. I only have two 80mm fans.
I'd go for a fan blowing in, and a fan blowing out danny.
To make sure there's decent airflow in the trolley, I'd try to mount the air in, on the opposite side, and above the output fan.
My preference would be two out at the top rear and a vent at the lower front.
I guess we will have many differing ideas.
