Review on 🌀 AC Infinity AIRCOM T9: Silent Cooling Fan System for Receivers, Amps, DVRs & AV Cabinets by Dante Jeppi

Product: AC Infinity AIRCOM T9 I bought an AC Infinity AIRCOM T9 to cool my Parasound amplifier. In a room with an ambient temperature of about 79 degrees Fahrenheit, the amplifier's heatsinks measured about 120 degrees Fahrenheit. 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 doing it yourself. AIRCOM T9 really works and works very well. surprisingly. At minimum fan speed (with mods installed), the temperature of the AIRCOM T9's front panel is about 12-14 degrees above the ambient temperature. My digital temperature gun confirms the temperature reading on the face of the T9 to the nearest degree. This is a significant improvement over the 40 degrees Fahrenheit above ambient I measured at the heatsink. Keep in mind that the T9 measures air temperature (the bottom of the T9), while the digital temp gun measures something solid like a heatsink and metal exhaust grille around the fans. The temperature gauge on the front continues to drop, but as expected, fan noise increases. At top speed I saw a difference of 5.7 degrees to the environment. But the fan noise was too loud for me even though the music drowned out most of the fan noise. If the fan is set to the third lowest value (out of a possible 6), the noise level of the fan becomes more acceptable. When I found that the lowest fan setting worked like a champ, I just left it on the lowest fan setting. At the lowest fan speed, fan noise is present, but almost, almost inaudible - consider it almost inaudible. It's so quiet that the guest won't hear it when the music isn't playing, and when the music is playing you certainly won't hear the fan noise. Hell, when the music isn't playing I don't notice it anymore and I have a critical ear. When using either the AIRCOM T9 or AIRCOM S9 (both pretty much the same specs) in a sealed case like most entertainment centers buy, I suspect that the top fan speed won't be audible since it's not as loud. The front panel display of the AIRCOM T9 can be switched off. A bit bright in a dark room when turned on. It fits me. Mods I made for T9. Around the perimeter, on the underside, I added a 5/16" x 23/64" D-shaped automotive and marine grade rubber gasket, a black EPDM rubber product I found at Lowes. I left the T9's legs in place and as I placed the T9 on the glass table top I saw that all of the gaskets were touching the glass surface just enough to deform enough to create a sealed chamber to allow air to flow freely through the amplifier. front, rear or side leakage. That's probably why the lowest fan speed works so well for me. I noticed one thing. The fans change speed slowly, meaning acceleration and deceleration times are gradual rather than instantaneous like my computer fans. I think that's a positive aspect. without being aware of the change in fan speed. Keep in mind. With the AIRCOM T9, the temperature sensor protrudes 1.2 mm from the underside. It can be felt with a finger wrapped around the center fan. don't confuse him. Disadvantages of AIRCOM T9? Another wall wart to contend with! Annoying, but that's a small price to pay for the AIRCOM T9's performance. The ambient temperature in the photo is about 75 degrees Fahrenheit. Without the AIRCOM T9, the temperature of the radiators would be around 118,120 degrees Fahrenheit. AIRCOM T9 is rated at 87 degrees Fahrenheit. The highest temperature I've ever measured on heatsinks was around 126 degrees Fahrenheit, and to be blunt, WITHOUT the T9 installed and its cooling. The design of the AIRCOM T9 is really good. Impressive build quality. The shipping box is strong enough for USPS/UPS shipping, although Revain put it in a different box. Thank you Revin! So would I buy the AIRCOM T9 again? Yes, but not for my amps. I think AIRCOM S9 will work fine. I don't really need the programmable AIRCOM T9 features for my amps. The amps I've had got hot and stay hot whether they're idle or playing music. All I need is constant airflow through the amp's heatsinks. I want thermal stability through constant airflow. I don't want the fans turning on and off. The goal is a constant air flow with a low noise level. Yes, I am satisfied with T9! I would probably be happy with the S9 too. I like the display on the front of the T9. Immediate feedback! Update: 08/17/18 I remain very satisfied with the purchase of the T9. Because of the cooling it provides, I think my amp has "better sound" than without the T9's cooling. Yes I know. all my imaginary sound voices tell me. I think the amp will last longer. Heat is a real electronics killer. I think some clarity about noise is needed. At the lowest fan speed I use, I can hear the fans in a quiet room with no music. Mind you, my amp is outdoors and nothing is blocking the fan noise. See photos. I found myself wondering what the "noise" was and when I realized it was a T9 fan I said "Oh good. 4 bigger, slower spinning fans would be better." However, the noise level is really low and when I play music at low volume I don't notice any fan noise. However, I am very, very happy with this purchase. All my imaginary sound voices are telling me that I'm great!
