AC Infinity, AIRCOM T9 AV Component Cooling Fan System 17”, Top-Exhaust

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!

Just unpacking this device you can feel its quite heavy, actually heavier then I had expected, but this is a good thing, as it shows this is not just a nice looking tin box with some fans in it and is in fact built to similar spec as the audio gear it protects. The T8 looks quite nice with my amp, however its clear the designers had Marantz in there minds when building this. The odd curved shape really only matches a Marantz I would love for them to make this exact device without the curved ends because AC Infinity If Your Listening most amps have flat face-plates so why is it designed around Marantz. Nitpicking aside the unit works very well and is easy to set up once you understand how the various modes work. The AIRCOM T8 comes with a small booklet explaining the setup. Once you have decided how you want it to work by choosing a mode, speed and a target temp for the fans to turn on its basically on auto pilot and I must say it works very well. My test subject is an Onkyo HTR as you may already know these amps can run very hot. I had an older one fail due to how hot it would get during just normal use. I got this to make sure my new Onkyo amp is kept at a nice even temp. So far this unit has been working so well that even after watching movies for part of the day the amp is just warm to the touch where before I added the T8 it would get pretty hot. Note: I do feel they should perfect it to make it quieter because in my opin its not as quiet as I would have liked and expected, but I keep it at 2 and its not too bad, so I wouldn't call this device whisper quite if that's what your expecting. I have mine in a BDI Media Cabinet and with the doors shut during a quite section of a movie I can still hear it a little bit and I wouldn't have this ever set on 5 which is pretty loud and there's no real reason in my setup to do so, Speed 2 keeps my amp at around 89 degrees and im fine with that considering it can go over 118 degrees with no cooling fans in a rack with closed doors. Do I recommend buying one? yes if you have a hot amp and especially if your gear is in a cabinet with closed doors then you will def want one of these its well worth the price.

I’m using the AIRCOM T9 on top of a Denon AVR, exhausting upward, paired with an AC Infinity AirPlate S9 at the rear of the TV cabinet. The two link together easily and work extremely well to pull hot air out of the receiver and then out of the cabinet. Build quality is excellent — solid, well-made, and it looks great sitting on the receiver. Setup is genuinely plug-and-play, and I really like that the display can be turned off so it isn’t distracting during movies or TV. Cooling performance is exactly what you want. Even in a generally cool room, AV receivers generate a lot of heat inside cabinets, and this setup keeps temperatures under control. Noise levels are very good — usually very quiet and only slightly audible during very quiet scenes depending on content. My only gripe is that you can’t set independent upper and lower temperature limits. Because of this, the fans can cut in and out as temperatures hover around the trigger point, which can be noticeable during quiet viewing. Proper temperature band control would make this close to perfect. That said, I still highly recommend it — especially if your receiver runs hot. Heat kills AVRs, and this does its job extremely well.

Fantastic appliance. I was previously using a USB desk top fan positioned behind my AV equipment to blow air across the top of my pioneer SCLX901 atmos receiver. It was fine for a while. Kept the receiver cooler than without a fan. But the fan wasn’t silent and was distracting. The receiver still got warm if run for a while. So I looked for something purpose built. This cooler is damn good. Sits seemlessly on top of my receiver and blends right in. I run it on auto mode and on the lowest fan-speed setting and the receiver stays cold, even after watching a couple of movies at an enthusiastic volume level, running all 11 channels and 3 subs. The cooler is silent. You don’t even notice when it comes on and off when it needs to. Even if run at higher fan speeds, I don’t think you even notice any noise. To answer an audiophile’s question, yes, the indicator light can be switched off by holding the mode button for 3 seconds, which is a great feature. There is an indicator light to tell you the unit is on, but it’s tiny and not a distraction. This unit has a rear exhaust, so consider this for your application. Definitely a must buy to protect your equipment, especially if you spend a high dollar amount on your stuff.

My Denon AVC-X4700H runs hot, almost disturbingly hot. My 4 ohm speakers only deliver 87db per watt so are a tough drive, and whilst my front speakers are driven by another amp, the AV amp still drives another 4 speakers and the subwoofer. The S9 has proved to be fantastic at reducing the running temperatures significantly and the auto temperature control function means you can leave it to its own devices which is a real plus. It turns on/off as required so no hassle there. It generally runs on setting one which is only just audible, but ramps up to setting 2 out of 3 under load. Overall I'm very pleased with it, its built well, looks good, and is well priced for what it offers. If you own a Denon/Marantz AV amp then these things are a great addition and the temperature reduction will likely significantly increase the product life from excessive heat wear & tear.

Tem um bom tamanho, silencioso e funciona muito bem!
