Review on 💨 AC Infinity AIRCOM S7: Top-Exhaust 12'' Quiet Cooling Fan System for Receivers, Amps, DVRs, AV Cabinet Components by Matt Williams

Excellent device. Very well designed with multiple options to work with. Install mine on my amp. Set it to turn on automatically depending on the temperature and also set the speed depending on the temperature. Very quiet and efficient in air travel. UPDATE: Added a second AIRCOM S7 on the DirecTV DVR. The DirecTV device generates a significant amount of heat, and the AIRCOM S7 dissipates it perfectly. As with the box on my amp, I set it to turn on automatically and set the fan speed based on the temperature sensor. Very impressed with how good the units are.
