This is my current set up for the Tempest Elite 410. The reason I have the front of the top two fans blowing down is so there is cool air flowing through my thermaltake frio. I highly suggest this for others as it has actually cool'd my system down 5-9*C.
Before I was hitting 50C idle and now I'm hitting 41C with on the lowest temp core.
edit: I might ghetto ziptie a fan behind the GPU so that air is flowed out better.
