AC Infinity AIRCOM T9, Quiet Cooling Fan System 17" Top-Exhaust 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!

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.

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.

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

My Marantz SR5015, purchased January 2021, started dropping the audio randomly in February 2025. No conditions had changed in my home, I checked all my connections and what not, everything was fine. I placed a small box fan next to the receiver and the audio turned back on. So it was an overheating issue. Being out of warranty and not wanting to have a box fan constantly blowing on my receiver, I immediately thought of AC Infinity as I've bought many of their products over the years and they've always been high quality. I purchased the rear-venting Aircom T8 and have been very happy with it. It's heavy duty, elegant, well made, and the front curvature aligns perfectly with me Marantz. It's a little bit deeper than my receiver so it hangs off the back a bit but keeping it flush in front with my receiver still has the fans lined up perfectly with the top vents of the Marantz, plus the bottom pads are still on the receiver. I played around with the Auto and Smart features quite a bit and, after doing testing and looking at research online, went with the Auto feature. The fan speed at 2 seemed to work the best but the noise bothered me slightly. I bumped it down to the lowest speed of 1 and it still is able to drop the temperature adequately. I have it set to turn on at 85 degrees, drop to 81 degrees, alarm at 95 degrees. So far it's never gone above 85 degrees! In reading reviews, the top-venting model has a lower dB although I wish these fans were just a little quieter. The instructions are just ok, you have to read every Mode setting carefully as they contain settings that affect how the Auto and Smart modes work. My recommendations to AC Infinity is to use quieter fans and update your instructions to be clearer!

Had the T10 for about 2 weeks now. Keeps the AVR cool, way cooler than it used to get w/o the fan, which is nice. Noise level is not that quiet at levels 4-6 but it’s still acceptable. My biggest pet peeve is that it doesn’t have a standby or power off mode. So, it’s basically always powered on, even with AVR off, which is a bit silly. I know, some are saying that you want to cool off the AVR even after you stop watching/listening, but the fan should still have a timeout after AVR is off to go in standby or power off. So, the display is always on, even when AVR is off, which turns the fan into the most over engineered ambient room temp gauge ever. :) Some mentioned the fan seems to continuously run, especially in smart mode. So, here’s what happens: . in on mode, you set the max level of fan, let’s say you set it at max 4. Then, there’s a buffer temperature level that is set at 4F by default, but you can change it to 2F; let’s say you do change it to 2F. . Then, in auto mode, the fan simply starts to run in max speed you set (4 in our case) once the AVR reaches the temp threshold you set (let’s say 85F) and stops running once the temp goes below 85F by the temp buffer (4F by default, but we changed to 2F, so it stops when AVR temp goes down to 83F, in our case). . In smart mode, the fan starts working preemptively as the temp of the AVR increases, reaching eventually max fan speed at 85F, increasing fan speed from 0 to 4, at each temp buffer increase. So, it kinda works backwards, from 85 you subtract 4 times 2F to figure out at which AVR temp the fan starts running at speed 1, then as AVR temp increases by another 2F, it increases speed to level 2, until it eventually reaches the max speed at the max temp you set. Then, on the way down, same thing: it would lower the fan speed by 1 level every time the temp of AVR goes down by the temp buffer (each 2F in our case, or 4F by default). So, In my case I set max temp at 85F, temp buffer for increase/decrease speed at 2F so, in smart mode, the fan would start running in speed 1 as soon as AVR temp reaches 85F (max temp) - 4 (max speed) x 2F (temp buffer) which is 77F; then, if AVR temp increases to 79F it would increase speed by another level to 2, then fan speed 3 at 81F and speed 4 at 83F. Same on the way down as AVR cools off. Of course if you leave the temp buffer at 4F and you set a different max fan speed, say 6 instead of 4, and a max temp threshold different from 85F, your numbers will be a bit different (the fan may start at even lower AVR temp). So, if you live in a very hot climate and your room temp is already at 75, or 77, and your fan is in smart mode, it would look as if it’s always running, but In reality, it’s simply preemptively keeping the AVR cool based on logic above. Anyway, hope this helps some. So, 4 star instead of 5 b/c no timeout to standby or power off and not that quiet at levels 4 and above; btw, the T10 is the front exhaust model which is the noisiest I think. The top exhaust one is the quietest, but you really need to the get the one that fits your space and I don’t have space behind or on top of AVR so had to get the front exhaust one.

I was originally concerned about noise, because places often say their products are quiet, and then I find out the fans are louder than they led me to believe. That is not the case with this, especially if you use the "smart" configuration feature, which steps up the speed of the fan every 2 or 4 degrees in a range of temperatures, so it can begin cooling without adding noise. As a result, I've seen it increase to Step 1 (lowest fan setting) many times to keep my Denon AVR cool, and it usually remains there, or shuts off when it cools it down a bit. I've only once seen it go up to Step 2 (out of 5 steps I think, where step 5 is the max fan speed), and it only remained there for a short bit before going back down to step 1. Even when operating at step 2 (i.e. speed 2 out of 5), I had to struggle to try to hear it in a quiet room. Pros: 1) It looks nice, and matches my Denon AVR nicely, in color, shape, and dimensions. 2) There are several models that allow you to choose what works best for you: air pushed to the front, the rear, or straight upward. I chose the T8, which pushes air backward, since I have an open entertainment center, and the heat can escape out the back. But they give you the option to choose which model is right for you: T8, T9, or T10. 3) Easy to "install". Basically, take it out of the box, set it on top of your AVR, and plug it in. It'll work right out of the box, and is that simple. 4) Easy to configure. If you don't want out-of-the-box default functionality, which I didn't, there are several operating modes you can choose from, and the instruction manual along with the interface controls make it very easy to figure out how to configure it -- very intuitive. I opted for the "smart" mode, which steps the fan speeds up and down as it automatically senses the temperature from the device. This uses less electricity, generates less noise, and is basically worry free. Cons: 1) It's kind of expensive. I was thinking of switching to a T10 model (front facing exhaust), in case I get a different entertainment center, but it was so expensive, I didn't want to spend the extra money, so I'm just sticking with my current entertainment center and the T8 rear-exhaust. I wish it was a bit less money, but I was obviously still willing to pay it. I probably would not have if it was very much more, and would've just opted to buy some other cheap fans for the top of my AVR. OVerall, it's a very good, high quality product, and I recommend it. Just make sure to purchase the correct model for your needs: T8 - Rear Exhaust; T9 - Top Exhaust; T10 - Front Exhaust.

Let me start by saying this is the easily the most deserving 5 star review I've ever given! I recently returned a buggy Onkyo receiver and bought a Denon. For my setup, the Denon works far better and while I couldn't be happier, I also couldn't help but notice this thing runs quite a bit warmer than the Onkyo did. My setup lives inside a dedicated closet with active ventilation, but I wanted something to keep the Denon running cooler, giving me better peace of mind for my equipment in terms of both longevity and performance. If you have a receiver/amp that tends to run warmer than you'd like, I couldn't recommend this unit more and it is worth every penny of the full price I paid for it! The first thing to consider is where your avr/amp has the most space for the exhaust to be vented. For me, I have my avr atop a floor-standing rack with 13" of empty space above, so I opted for the T9 unit. *It's important to note that the 8 series exhausts rearward, the 9 series exhaust upward and the 10 series exhaust frontward, depending on what would be ideal for your needs. I experimented with turning it off and running my system for a bit, then turning it back on to 'smart' mode to see the difference. In 'off' mode, I saw probe temperatures registering on the T9 of 94 degrees after watching a movie for 20 minutes or so of action. Upon switching the unit back on to 'smart' mode, I immediately noted the temperature slowly decreasing, on down to 79 after about another 20 minutes or so. I would be remiss if I didn't mention the fantastic build quality and appearance of the unit. It feels like a serious piece of home theater equipment: solid, sturdy and heavy, deserving a space anywhere from a modest home entertainment console to a custom rack full of high end equipment.

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。

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
