My Raidmax Smilodon case comes with two fans mounted on the side. One is a fan which blows on the GPU from the outside. The second fan draws air from inside the case directly in line with the cpu/heatsink & fan. Would it be better to flip it around and blow outside air onto the heatsink/fan or leave it? I'm Using a Zalman 9900 led on an I7-2600K. The heatsink lines up directly in front of this side fan.
