Its odvious to me that my 450gph hydor pump is a huge heatsource. I figure making a closed aluminum "case" for the pump, filling it with water, and mounting it in the hard drive cage will reduce temps. And dont mistake me, the water in this "pump case" would not be used in the loop. The intake fans would assist in cooling the "pump case". I also could use my old cpu heatsink to attach to the "pump case". This would also help make the pump incredibly silent I assume, provided you use rubber washers to mount it.
