AC Infinity AIRCOM 17-Inch Top-Exhaust AV Receiver Fan

AIRCOM S9 and T9 vent straight up instead of out the back, for cabinets where a rear exhaust would just blow into the shelf above. Three dual-ball-bearing blowers pull heat off the top of a receiver, amplifier, or DVR at up to 210 CFM; the S9 runs on a simple thermal trigger, while the T9 swaps that for an LCD controller with a probe, on-screen temperature readout, and adjustable trip points.

Both share the low-profile AIRCOM chassis, a 30-pound top-load rating, and PWM-controlled blower motors tuned to keep noise down. A 6-foot cord runs to a standard wall outlet, and the T9's rear ports can also drive additional compatible AC Infinity fans.
