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 ### ⭐⭐⭐⭐⭐ Very impressive product, highly recommended *by on Reviewed in the United Kingdom 24 April 2021* 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. ### ⭐⭐⭐⭐⭐ A great piece of kit! *by on Reviewed in the United Kingdom 3 March 2025* A brilliant piece of kit. I was using a laptop fan before but this is in a different class. Beautifully built, all metal. Fans are very quiet. Can be programmed to automatically come on when the temperature rises and then it goes off. Please note you do need a us to UK plug adapter as this comes direct from the USA. I'm very satisfied. ### ⭐⭐⭐⭐⭐ Perfect for cooling my Marantz pm7000n amplifier *by on Reviewed in the United Kingdom 11 November 2025* Recently I noticed that my Marantz amplifier was getting hot. Marantz suggest that inch clearance is given at the top of the amplifier or use a fan. Since I'm unable due to space to provide the recommended clearance I opted to go for a fan solution.The AC Infinity works perfectly; cooling the amp with very little noise.Easy to install and use, with good documentation. Also came in a well padded box.I have it currently set to SMART mode. In this mode the fans start when the temperature reaches around 88 degrees F (31 Degrees C), then shuts off below 84 degrees F (29 Degrees C). The fan speed increase every 2 degrees above 88, but currently it have not risen above 88, and seems to be doing a good job at cooling.The S7 is smaller than the amp, may be the larger unit would be better for looks, but it is almost double the price of the S7.My unit came with UK plug power supply, so I did not need a US to UK adapter as others have stated.At low fan speed, I can't hear any fan noise.The unit when sat on top of the amp sucks air through the amp in the direction that normal convection cooling occurs. This is correct as you don't want it to blow air into the unit against the follow of the rising heat.So far the unit is performing perfectly. I wish Marantz had designed the amp with a built in fan! ## 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.id/products/52124108-ac-infinity-aircom-s9-quiet-cooling-fan-system-43-cm](https://www.desertcart.id/products/52124108-ac-infinity-aircom-s9-quiet-cooling-fan-system-43-cm) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-08-15*
