(Whole Product) PDF Product Manual Product Manual PDF Review: Sleek, elegant, and keeps your AVR cool! - Got this one because it was cheaper than the one with the temperature reading. I figured I need the Aircom S10 because my AVR is in the entertainment stand, and has been getting fairly warm. Ever since I put this on top of my AVR, it blows nothing but cool air. This one also has an auto feature and all you have to do is plug it in to the power strip; very easy to install! It will turn on, off, and adjust the fan speed automatically. It looks sleek and is pretty low profile. This product is also very quiet at every level, except for the max setting. It does such a good job that it doesn’t need to go that high, and it’s not loud enough to hear over your movie/tv show anyway. Your HVAC unit will probably be louder than this fan. Review: Cooled Amp as if It Was Not Even Powered On! - ** EDITED REVIEW MAY 7, 2022: After using for 1 year, the Aircom S10 continues to impress. I did make one change, however, to the settings below. The change was to set the device to Mode=Auto/Fan=Low. The reason for the change is that I kept forgetting to turn the fan off manually when set to Mode=On/Fan=Low. I also had the occasion recently to check for dust build-up, and I am happy to say the amount was minimal - the fact of which I attribute to the low fan speed setting. ** MODEL PURCHASED: S10 (w/front exhaust) COOLING SETTINGS USED: "Mode=On/Fan=Low" TRICK TO GET FAN SPEED LIGHT TO TURN OFF: Press and hold Mode/Power button (far left while facing unit) for 3+ seconds, then release and wait a few seconds for fan speed light to turn off. When the fan light is "Off" it is truly invisible behind the faceplate bezel, as you can easily see (or not see!) for yourself in the attached pictures. MODE/POWER LIGHTS REMAIN ON: The mode lights - which double as "Power=On" lights - will remain lit depending on mode selected. However, they are not overly bright. In my case, using the "On" mode, only the very tiny white light remains lit. I did not find it distracting. TRICK TO TURN UNIT OFF: Press and release the Mode/Power button to cycle through the modes to reach power off state. In my case, 4 presses are required to reach power off state. AMP USED: Twenty-plus year old NAD 906 Multi-Channel Amplifier with three separate (and very large) power supplies, and six discrete/bridgeable channels. The NAD 906 amp was advertised as having "high quality, high temperature" components. Inside there is a lot of chunky metal, so to speak, that not only produces its own heat but also holds any heat around it. Most significantly the amp has no fans, which is a tip-off it was designed and built for consistent performance at high levels of heat. However, when considering the massive amounts of chunky metal inside, it is clear that the 906 would shed heat very efficiently with any kind of increased air movement across any of the metal, especially the large heat sinks. AMP DUTIES: 4-channel Atmos/DTS-X amplification of "Dolby-enabled" Height 1 and Height 2 speakers line-out signals from NAD 758 v3i receiver. (Note: On the NAD 906 amp, I employed two channels on far right of chassis and two channels on far left of chassis to widen heat distribution/dispersion.) AMP PLACEMENT: Cabinet shelf, two 2" holes in cabinet back cover, open front, no other electronics in same shelf or above/below. SEE BELOW for AMP TEMPERATURES at VARIOUS AMP STATES (Note: Measurements taken at center/top of amp cover, and room temperature is 75f average): With Fan NOT In-place/NOT In-use (i.e. prior to purchase): 77f - Amp Off (TV, lamps, and exterior wall by cabinet create ambient heat increase 2f higher than room average) 94f - Amp On/Idling, RCA inputs from receiver not active 111f - Amp On/Idling, RCA inputs from receiver active but w/no signal (strong "Class A" bias?) 120f - Amp On, temp after 140min movie w/Atmos content ("Ready Player One") With Fan IN-PLACE/IN-USE but removed for measurements AFTER MOVIE: 77f - After movie, amp immediately turned off, fan immediately removed, amp temp immediately measured after 140min movie w/Atmos content ("Ready Player One") 85f - Amp left off, fan still removed, and temp measured after 20 minutes 86f - Amp left off, fan still removed, and temp measured after 40 minutes PERFORMANCE/TESTING CONCLUSION: The AIRCOM S10 performed beyond expectation, using low and quiet air flow to keep my amp at 77f while in normal use, which is as cool as it is when powered off. To give some credence to the above active cooling effect's astonishing measurement of 77f, you can see from my other measurements that the heat increased (as expected) after the amp was off and the moving air's wicking effect was removed. Still the amp's heat had only increased to 86f after 40 minutes. I am confident leaving the fan on for 5-10 minutes after the amp has been powered off would wick away most if not all the residual heat from the sinks. To be fair, the amp is not cluttered inside, has enough slits in the top and bottom shrouds to easily call them screens, uses very large heat sinks that allow for amazingly quick heat conduction, and the movie was not overly loud. OPERATIONAL TESTING/CONCLUSION: I did not want to wait for the amp to reach the mid- to high-80's before the fan would automatically turn on, so I avoided all of the S10's automatic settings. In my testing, and now ongoing use, I decided to just manually turn it "On" at its lowest setting (which is very quiet) when I started watching a movie, and thus it would always stay many degrees ahead of the amp. Said another way, by turning the fan on at the same time I begin using the amp, the fan would not have to "play catch-up" with the amp if the amp had been allowed to get hot, first. I work with huge servers in datacenters (and have my own computers) and, in my opinion and based on experience there is no real benefit - aside from convenience, which will understandably be the winning feature to others - to waiting for a fan to do its job later rather than sooner. Now, what I will do differently in the future - distinct from my measurement process above - is let the fan run for a little while after the amp is turned off. VALUE CONCLUSION: With over 20+ years under the belt of my NAD 906, the AIRCOM S10's outstanding ability to remove heat from that hot-running amp will only help it remain stable and useful longer than otherwise. And the cost of the AIRCOM S10 is far, far less expensive than buying a new amp of similar quality. ## Features - A quiet fan system designed for cooling receivers, game consoles, and other AV components. - Protects components from overheating, performance issues, and shortened lifespans. - Programming features two thermal trigger modes and four speed control options. - Contains three dual-ball bearing fans with PWM-controlled motors to minimize noise. - Dimensions: 17 x 13.5 x 1.5 in. | Exhaust: Top | Airflow: 210 CFM | Noise: 21 dBA ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01LVUWOBX | | Air Flow Capacity | 210 cfm | | Best Sellers Rank | #86 in Computer Case Fans | | Brand | AC Infinity | | Brand Name | AC Infinity | | Compatible Devices | Gaming Console | | Cooling Method | Air | | Customer Reviews | 4.8 out of 5 stars 4,457 Reviews | | Item Dimensions L x W x H | 17"L x 13.5"W x 1.5"H | | Manufacturer | AC Infinity | | Material Type | Alloy Steel | | Maximum Rotational Speed | 6700 rpm | | Model | AI-ACS9 | | Noise Level | 21 db | | Number of Items | 3 | | Part Number | AI-ACS9 | | Power Connector Type | SATA/Molex or 3-pin/4-pin | | Product Dimensions | 17"L x 13.5"W x 1.5"H | | UPC | 854759004655 | | Unit Count | 1 Count | | Voltage | 12 volts | | Wattage | 35 watts | ## Product Details - **Brand:** AC Infinity - **Compatible Devices:** Gaming Console - **Cooling Method:** Air - **Material:** Alloy Steel - **Maximum Rotational Speed:** 6700 RPM - **Noise Level:** 21 Decibels - **Power Connector Type:** SATA/Molex or 3-pin/4-pin - **Product Dimensions:** 17"L x 13.5"W x 1.5"H - **Voltage:** 12 Volts - **Wattage:** 35 watts ## Images ![AC Infinity AIRCOM S9, Quiet Cooling Fan System 17" Top-Exhaust for Receivers, Amps, DVR, AV Cabinet Components - Image 1](https://m.media-amazon.com/images/I/51iWLsgbqXL.jpg) ![AC Infinity AIRCOM S9, Quiet Cooling Fan System 17" Top-Exhaust for Receivers, Amps, DVR, AV Cabinet Components - Image 2](https://m.media-amazon.com/images/I/61X9wtfAygL.jpg) ![AC Infinity AIRCOM S9, Quiet Cooling Fan System 17" Top-Exhaust for Receivers, Amps, DVR, AV Cabinet Components - Image 3](https://m.media-amazon.com/images/I/61CbqsaKdgL.jpg) ![AC Infinity AIRCOM S9, Quiet Cooling Fan System 17" Top-Exhaust for Receivers, Amps, DVR, AV Cabinet Components - Image 4](https://m.media-amazon.com/images/I/61CkRH33SUL.jpg) ![AC Infinity AIRCOM S9, Quiet Cooling Fan System 17" Top-Exhaust for Receivers, Amps, DVR, AV Cabinet Components - Image 5](https://m.media-amazon.com/images/I/61JQCNcrbsL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: i have a denon avr s940h reciever in an enclosed cabinet with 4 inches from top of reciever to top of cabinet. Will the s9 or t9 work?** A: 4" from the top of your receiver means only 2.5" from the top of the AIRCOM S9. This may be too little clearance for a top-exhaust unit. You say "enclosed cabinet." I assume one side is open. The hot air needs to vent somewhere. If this is true then go with a front or rear exhaust system instead. The AIRCOM S10 is the front-exhaust version and S8 is rear-exhaust. Also, I like the S-Series because it offers all the control over the fans that I require. The T-Series costs more and seems a little overkill. Unless, however, you really like the LCD display. **Q: Will this work in automobile applications** A: It works off of 120. You should call the company and ask them if they have fans for automotive applications. **Q: does anyone use these fans in a stack? in between 2 components (amp, fan unit, avr for example)?** A: As long as you have proper clearance I don't see why it wouldn't cool ok. I think it pulls air upwards better than pushing air but I have used it to push air up thru an amp. **Q: Have a receiver in a cabinet with 3.5" space behind it to back of cabinet or about 5" above it to a glass shelf. Top or rear exhaust unit is better ?** A: This unit exhausts from the top and I have about 1 inch above the unit. It works perfectly. I’ve had no problems with the receiver overheating, since I purchased the fan. If you have 5” above, it should work very well for you. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Sleek, elegant, and keeps your AVR cool! *by N***K on July 9, 2026* Got this one because it was cheaper than the one with the temperature reading.

It's working great, so far, to cool my Denon receiver. The 2 fans are turning on and off automatically as expected (on when enough heat is detected and off when not enough heat). It's not totally silent, but it's pretty quiet, and I can't hear it from my normal seating position (at low fan speed which is what I use). Installation was easy. Configuration was easy. I configured it so that the only sign of life is a small orange LED. I turned the fan speed indicator off because it was a bit too bright. Check out my photo... but ignore the dust. Pretend it's not there. ## Frequently Bought Together - AC Infinity AIRCOM S9, Quiet Cooling Fan System 17" Top-Exhaust for Receivers, Amps, DVR, AV Cabinet Components - AC Infinity AIRCOM S10, Quiet Cooling Blower Fan System 17" Front-Exhaust for Receivers, Amps, DVR, AV Cabinet Components - AC Infinity AIRCOM S7, Quiet Cooling Fan System 12" Top-Exhaust for Receivers, Amps, DVR, AV Cabinet Components --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/33759253-ac-infinity-aircom-s9-quiet-cooling-fan-system-17-top](https://www.desertcart.tw/products/33759253-ac-infinity-aircom-s9-quiet-cooling-fan-system-17-top) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-07-27*
