I am using a stock HP envy case, and I've got a 970 that could use a little more air sometimes. I was thinking about mounting a fan on the side panel, but it's only about 2-3 inches wide and about 2 inches tall. Small vented grill, but it's one of the only ways I can think of to get some fresh air in that upper compartment. I was looking at an Antec SpotCool fan, but It's a little expensive for a fan, so I thought about going with a blower fan and mounting it in the side of the upper top. The video card fans face upwards on the case, and the only vents are on either side of the panel. What would be the best way to suck a little more air through the panel?
