After adding some thermally controlled exhaust fans, I thought it would be good to address the intake side of things. The Middle Atlantic DWR-12-32 has 150mm fan mounts top and bottom, but with 2U of space on the front my preference was to try an active front facing intake. After some research, and a dearth of options, I found the $100 programmable Coolerguys 2U bracket with four 80mm Evercool fans. Overall, this cooling solution does what it intends to do, most of the time, but there are a few characteristics which make it less than perfect.
