HTPC/gaming rig for the lounge and sits horizontal on a shelf, pulling air in through the I/O side and pushing it down the front panel (sealed up the mesh and chassis holes) and into the 1st rad, then ducting into the second rad and out the bottom via the 2nd 140mm fan. Still playing around with settings but so far it seems happy with the GPU @ 1980Mhz & CPU @ 3.95 Mhz, both running 60 degrees and the water loop hoovering around the 45-48 degree mark. This is a very quite setup at full load with the fans @ 1500rpm, during lite use/idle only the chassis fan is running @ 30%
