Goto 2cooltek.com and check out the 5.25" bay cooler they have there. Has two fans, one intake, one exhaust, moves quite a bit of air in my opinion. The intake channels the hot air through a passage in the top of the cooler, and the exhaust then exits the air out the fornt of your system. I dont find it that noisy, actually sometimes I have to turn the case slightly sideways because the short breeze it blows out can become a bit chilly. LOL
You have a full size ATX tower, and with that many bays, Id get two bay coolers, put one in the top bay and one in the bottom bay for maximum cooling.
