LCD thermostat programming with six speed controls, alarm alerts, failure triggers, and memory. Contains three dual-ball bearing fans with PWM-controlled motors to minimize noise. Dimensions: 17 x 13.5 x 1.5 in. | Exhaust: Top | Airflow: 210 CFM | Noise: 21 dBA | Bearings: Dual Ball Product Description A quiet cooling fan system designed to be placed on top of AV components such as receivers, amplifiers, and DVRs. Maintaining an optimal temperature for components prevents overheating, ensures constant performance, and extends their lifespan. The LCD digital controller on the front of the system features a smart thermostat with speed control and status alerts. The steel enclosure houses three dual-ball bearing blowers that pull heat out of the component and exhaust out the top. The dual ball bearings also allow this fan system to be mounted horizontally or vertically. Its slim low-profile design enables the unit to fit in tight spaces. On the backside are ports to connect and control additional fans. Includes corded power adapter to plug the fan system through an outlet. Intelligent Programming Programming includes an easy-to-use thermostat and a SMART mode that automatically adjusts the fan’s speed to react to varying temperatures. Additional features include alarm alerts, fan failure triggers, power savings setting, display lock, and backup memory. Six fan speeds are available with three screen brightness settings. Behind the unit are ports that can control up to six individual AC Infinity AIRPLATE Cabinet fans and MULTIFAN Component fans. Design and Construction Each system features dual-ball bearing fans rated at 67,000 hours and are certified by CE and RoHS. Fans contain a PWM-controlled motor used to minimize noise during speed variations and are suspended in mid-air with silicone mounts to absorb vibrations. A low-profile design allows the unit to fit in applications with a limited height clearance. Aluminum and steel construction enables additional components up to 30 pounds to be stacked on top.

- Reviewed in Canada on August 17, 2017Verified PurchaseThis product works as advertised. I have it on an older Yamaha receiver which is mismatched to some new large tower speakers. I love to get large volume out of my system and be immerced in my music. But my poor receiver heats up well enough to heat a cold room in the coldest winter months, which I believe degrades the electronics over time much faster. The Aircom T9 has solved the issue well. When left on auto, the fans come on and the sound is insignificant. It cools the amp right down and does so fast. I love this unit and seriously recommend it. It looks very cool too. Lots of adjustments as well. It feels well made and works as advertised.
- Reviewed in Canada on July 24, 2024Verified PurchaseI will simply echo the other more detailed positive reviews here. I have the T9 sitting on top of my Marantz home theatre reciever and it absolutely looks like it is part of the reciever. I use the smart setting. The Marantz used to shut off once in a while via it's internal thermal protection circuit. No more. I can run it hard without issue. The fans are very quiet. The display brightness is not annoying. All in all I love it. It certainly looks better than some jury rigged computer fans lying on top.
- Reviewed in Canada on January 9, 2017Verified PurchaseAdded this to my Marantz AV as it was running over the recommended max of 85 degrees. This cooling fan component works exactly as described. Fit and finish are very high and the display settings are user friendly. I also like the fact that the display can be dimmed three levels so I can check on the status, while not having it be too bright in my home theater room.
The six speed settings means that at the lowest speed, the unit is very quiet, while still extracting the heat away from the unit. Highest speed setting is claimed at 28db and that sounds about right. Fortunately, I don't see any reason to use it when in auto mode. I contacted AC Infinity customer service on a few occasions for product info and they were very quick to respond. I consider it to be an excellent value, given the performance and quality fit and finish.

- Reviewed in Canada on January 22, 2021Verified PurchaseWorks like a charm, my Onkyo was running about 100 f now it runs a steady 80 f. For us Canucks it was running about 48 to 50 c now it runs at a steady 26c. Set to smart the fan is running at lowest speed I simply do not hear it. Fits well, moved it back from the front of the unit to get better coverage over the hot spots. I would buy it again.
- Reviewed in Canada on May 5, 2018Verified PurchaseLooks and works beautifully. Only issue would be that you can still hear the fans when listening to audio at low volume levels.
- Reviewed in Canada on May 6, 2025Verified PurchaseJust got this unit... and absolutely love it so far. The quality is definitely there, and all things considered it ruins very smoothly and is not loud at all. I would expect a whole lot more noise . The external casing is made from a decent heavy duty metal construction giving that premium feel.

5.0 out of 5 stars Es muy utili y me encanta la calidad
Verified PurchaseDesde que recibes el equipo y abres la caja y notas lo detalladamente que esta empacado y al sacarlo del empaque lo confirmas. esta excelentemente terminado. lo uso en mi amplificador Arcam SA 20 que se calienta, aun al usarlo al 40% de su capacidad. si lo ponen en la velocidad 1 incluso 2 es casi imperceptible el ruido, ya apartir de 3 si suena pero ya en esos requerimientos también la música esta a un volumen mas alto y ya no se percibe. solo en espacios en blanco en la música te das cuenta de que esta funcionando . baja casi a temperatura ambiente la temperatura del amplificador . me encanta como suena mi sistema y no me importaría quedarme asi muchos años y con esta adición estoy seguro que ya la temperatura de los circuitos internos no sera problema. yo lo uso en manual porque la habitación en donde esta mi equipo es pequeña pero el equipo tiene un par de modos completamente automáticos y configurares.
