AIRCOM T9, Quiet Cooling Fan System 17" for Receivers, Amps, DVR, AV Cabinet Components

ok

Desde 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.

The producy has worked extremely well. It is quiet and keeps the receiver cool even over an extended period.

Product: AC Infinity AIRCOM T9 I bought the AC Infinity AIRCOM T9 to cool down my Parasound amp. Sitting out in the room, with an ambient air temperature of about 79 degrees F, the amp's heat sinks were measuring around 120 degrees F. Hot to the touch. I started looking for a cooling solution and when I came across the AIRCOM T9, I thought this product might work. Better than building my own... The AIRCOM T9 does work and it works really well... amazingly so. On the lowest fan speed setting (with my mods in place), the AIRCOM T9 front panel temperature reports about 12-14 degrees above ambient. My digital temperature gun confirms the T9’s front panel temperature readout within a degree. This is a vast improvement over the 40 degrees F above ambient I was measuring at the heat sink. Keep in mind the T9 is measuring air temp (bottom side of the T9) where as the digital temperature gun measures something solid, like the heatsink and the metal discharge grate around the fans. If I turn the fan speed to a higher setting, the front panel temperature reading drops even more, but as expected, the fan noise increases. At the fastest speed setting, I saw a 5, 7 degree difference from ambient. But the fan noise was too much for me, even though the music obscures most of the fan noise. With the fan set to the third lowest setting (out of 6 possible settings), the fan noise level is much more agreeable. When I discovered the lowest fan setting worked like a champ, I just left it at the lowest fan setting. At the lowest fan speed setting, the fan noise is present, but its nearly, almost inaudible - consider it essentially inaudible. It’s quiet enough that guest won’t hear it when the music isn't playing and when the music is playing, for sure, the fan noise isn't heard. Heck, when the music isn’t playing I don’t notice it anymore, and I've got the critical ear. If either the AIRCOM T9 or the AIRCOM S9 (both have essentially the same specs) is used within a closed furniture cabinet, like most entertainment center’s people buy, I suspect the highest, fastest fan speed would not be heard as its not that loud. The AIRCOM T9 front panel display can be turned off. When on, its a bit bright in a dark room. Its fine for me. The mods I made to the T9... around the perimeter, on the underside, I added a “D” shaped 5/16” x 23/64” Auto and Marine Rubber Weatherseal, a black colored EPDM rubber product I found at Lowes. I left the T9’s feet in place and when I placed the T9 on a glass table top, I could see all the seals were touching the glass surface sufficiently, deforming enough to create a sealed chamber in order to pull the air through the amp without any front, rear or side leakage. This is probably why the lowest fan speed setting works so well for me. One thing I noted... the fans are slow to change speed, meaning the spin up and the spin down time is gradual instead of an instant change of speed like with my computer fans. I think this is a positive aspect... not becoming aware of the fan speed change. Keep in mind... the AIRCOM T9 has a temperature probe protruding 1, 2 mm on the bottom side. You can feel it with your finger, located around the middle fan... don’t knock it off. The downside to the AIRCOM T9? Another wall wart to deal with! Annoying, but its a small price to pay for the AIRCOM T9’s performance. The ambient air temperature in the photograph is around 75 degrees F. Without the AIRCOM T9, the heatsinks would measure around 118, 120 degrees F. With the AIRCOM T9, 87 degrees F is great. The highest temp I've ever measured at the heatsinks was around 126 degrees F, and to be CLEAR, WITHOUT the T9 in place and doing its cooling thing.. The construction of the AIRCOM T9 is really good. Impressive construction quality. The packing box is solid enough for USPS/UPS shipping, though Amazon put it in another box. Thanks Amazon! So, would I buy the AIRCOM T9 again? Yes, but not for my amps. I think the AIRCOM S9 would work just fine. I really don’t need the features of the programmable AIRCOM T9 for my amps. The amps I’ve owned get hot and stay hot, regardless if they are idling or playing music. A constant flow of air through the amp’s heat sinks is all I need. I want thermal stability from the constant air flow. I don’t want the fans turning on and off. Constant airflow with little noise is the goal. Yeah, I’m happy with the T9! I’d probably be happy with the S9 as well. I do like the T9’s front panel display... Instant feedback! Update: 8/17/18 I continue to be very pleased with my purchase of the T9. Because of the cooling it is providing, I think my amp has a "better sound" than without the T9 cooling. Yeah, I know... all of my imaginary audio voices are telling me so. I do think the amp will probably live longer.. heat's a real killer for electronics. I think some clarity is needed about noise... on the slowest fan speed setting I use, in a quiet room without any music playing, I can hear the fans. Mind you, my amp sits out in the open without anything to block the fan noise. See the pictures. I've caught myself wondering what that "noise" was, and when I realized it was the fans from the T9, I said, "Oh, OK... 4 larger, slower turning fans would have been better". Still, the noise level is really low, and when I play any music at a low volume settings, I do not notice the fan noise. Regardless, still very, very happy with this purchase. All of my imaginary audio voices are telling me I brilliant!

Ordered it for my Denon AVR which is in an enclosed cabinet. Set up takes just a few minutes and looks great. Solid metal construction and comes with a multi voltage power supply ( 2 pin, so you will still need an adaptor plug if you are in Ireland or the UK , but these are very cheap to buy ) . Delivery time was excellent , so credit to the seller - less than 1 week , and well before the expected delivery date given by Amazon. Somewhat pricey , but still cheaper than importing from the US , and the best value on this site. Quiet in use , so long as you don't set the fan speed above 3 ( depending on where you have your amp set up ) . I have it set to smart , so the fan speed will adjust automatically depending on the heat generated by the amp , and switches off when the target temperature is reached. It's pretty much "set-and-forget" , and you can also lock the settings to prevent accidental changes. Value for money will depend on your amplifier - for high end amps costing a lot , it's good value to protect your investment. Recommended
