AC Infinity Rack Roof Fan Kit with Speed Controller

Heat in a closed rack collects at the top, and this kit takes it out where it gathers. Two 120mm dual-ball-bearing fans bolt into the roof panel of the rack and exhaust upward, moving 200 CFM combined at 26 dBA. Static pressure is rated 5.5 mm-H2O, so the pair still pulls through a perforated or filtered roof rather than stalling against it.

A separate speed controller mounts into a 2.95 x 0.51 in. cutout and runs on a 6-foot cord, letting you trim airflow down until the rack is quiet enough for the room it lives in. The fans daisy-chain to each other on a 10-inch lead and run on 12V DC from an included 100 to 240V wall adapter, and they can be mounted horizontally or vertically. Bearings are rated for 67,000 hours L10 life.
