AIRCOM T8, Quiet Cooling Blower Fan System 17" Rear-Exhaust | For Digital Video Recorder for Receivers, Amps, DVR, AV Cabinet Components

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!

This in an outstanding product. It works as advertised. The setup is straight with good instructions. I've had it over a year and it's still working strong. I love all the options and most importantly it keep me audio system/power amp cool. It's reliability, little to no noise, airflow is good and it just perform. I stronly recommend this product.

Awesome product. Very well built. It's keeping my surround receiver very cool. And goes great with all my equipment. You have many options in the settings also. Three really heavy duty fans under side. And it's quite. A must have. Well worth the purchase

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.

Overall, I have to say that I've been really pleased with the T8, even though I'm still getting my set-up together and have barely had a chance to use the two I bought. But in trying to plan out my system, I've run into a few improvements I would like to see. For older receivers that produce a LOT of heat and have switched outlets, this is an excellent add-on. But as I've been trying to incorporate a more modern home theater receiver into things, I've been faced with the harsh reality that most receivers made now do not have switched outlets. Now with the thermostatic control, it's not a huge deal if the T8 stays on all the time, it will cool off and shut the fans off and use virtually no power. But most receivers I have looked at lately DO have a 12v trigger output (in lieu of a switched outlet), and from what little looking I have done, there is nothing that takes advantage of these (I haven't found any 3rd party premade 12v relay switches, even though they would be simple to build) aside from possibly subwoofers. I think a 12v trigger input would be a GREAT addition to the AC Infinity cooling systems, as it would allow the Aircom to shut down completely with a receiver in the modern world. I saw the USB outs on my Yamaha and thought I could at least buy some additional fans to put on it that were powered by USB, but then found that the ports weren't switched! So with this receiver (and all I've looked at), the only way to switch the fans automatically would be to construct something to work off the 12v trigger port. Back to older receivers, the Aircom seems to work great, it's the perfect size and seems to work perfectly and also quietly, and looks awesome. The only issue I ran into was the "wall wart" power supply taking up too much space on the back of the receiver. Depending on the placement and orientation of the outlets, that transformer can run into other connections and/or block other outlets from use. On only my second temporary set-up, I found myself grabbing another power supply that had a cord running to the transformer, rather than blades sticking out of one, because of the Aircom transformer being in the way of the power input for the receiver (this was on an older Yamaha). To sum up, I think the T8 is a GREAT product, but it would be a perfect (and more universal) solution if it had a 12v trigger input and a power supply with it's own AC cord instead of the typical "wall wart"

Works great, looks good, it immediately cools the receiver down and drops a couple of degrees in about 10 seconds, tried with multiple temperatures and it works great! The fans are very quiet and the only time it runs is when the system is working hard so really I hear nothing. Smart Control is nice, easy to set and navigate. Only has a 2 degree on-off, would be nice if you could change that but no biggie. I did however run into FM reception problems as a few did, I put some ferrite beads on the antenna and the fan unit power cord and was able to get it pretty good, worst case is I unplug it as you can’t turn it off. This thing works amazing

I had used a couple of discreet very low noise PC fans, with built in sensors to vary their speed, but it proved difficult to consistently get the heat up from the Amp and out of the AV Cabinet. One look at the AC Infinite Aircom T8, however, and I just had to have one. With my living room AV Cabinet setup of enclosed glass door fronts, solid sides and open back it was just what I needed. My nice new but rather too warm at times Denon AV Amp has heat vents across the whole top serface, so the way the T8 pulls hot air from the Amp and passes out of the cabinet at the back is perfect. The three fans run at 6 levels, however, they are rather noisy above level 2 for me at a seating distance of around 10 feet away. Such noise issues are subjective and it depends on surroundings, room acoustics and the music and movies listened to. For my use the low 2 fan settings seem fine in Auto Mode as the Amp doesn’t need to run cool, just not overheat. Keeping the top of the Amp under 95F/35C seems a decent compromise, but there is a lot of controversy in this area so folk need to make their own minds up as manufacturers don’t seem to want to get involved. Apparently, all modern Amps should have protection that warns or even turns off if the internals go above ‘safe’ levels, but it seems difficult to get definitive advice so I feel it’s better to help enclosed Amps keep temperatures down. Looking at the AC Infinity website and they seem to recognise ‘fan issues’ including stating that other replacement fans are available from suppliers providing they match the required voltage and size. I’ll see how I get on and update this review with any significant findings. It’s always a compromise between airflow, noise and cost so how the T8’s are shipped is a very good package. I knocked a star off under the ‘noise review’ section but otherwise it’s 5 stars all around from me. I’m more than content with the how it cools my Amp that seems to have several areas where heat builds up depending on what it’s doing - HDMI AV, different levels of Dolby & DTS processing and music from built in and external sources. So it’s still early days... It certainly looks amazing and even seems to enhance the look of my Denon AV Amp, which also has a black finish. For UK Customers: While this has been on sale from Amazon UK it wasn’t at the time so I purchased from USA Amazon.com. While there was obvious shipping, tax and import duties these were reasonable considering buying in the UK has a 20% VAT/Sales Tax. It was also made clear what I needed to pay in total before committing and the tracking and rapid delivery was perfect via FedEx.

Very fast delivery. The AC Infinity AIRCOM T10 fits almost perfectly on top of my Denon AVC-X3800H and looks very clean. It keeps the receiver very cool; I use Smart Mode with 35°C as the trigger temperature and 43°C as the alarm. The unit itself is excellent, quiet and effective. It also helps cover the top ventilation area, so dust cannot fall directly into the receiver from above. However, my unit came with a US power supply and a cheap loose EU adapter. I strongly recommend that nobody uses the included adapter. In my opinion it feels unsafe and could be a fire risk, especially behind expensive HiFi/AV equipment. I replaced it with a proper SKROSS adapter before use. Great cooling unit, but the included adapter should be replaced immediately before connecting the product.

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.

とても重宝しています。 アンプも熱くならず、とても良いです。 ただ、別にオンとオフのスッチがあればなぁと思いました。 設定のfanをOffするのは少し手間なので。 しかも温度センサーは動いているので。
