## Description

AC Infinity AIRCOM S7, Quiet Cooling Blower Fan System 30cm Top-Exhaust, for Receivers, Amps, DVR, AV Cabinet Components, Digital Video Recorders, 12-Inch : desertcart.co.uk: Business, Industry & Science

Review: Very impressive product, highly recommended - 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.
Review: A great piece of kit! - 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.

## Questions & Answers

**Q: Are these push or pull fans? Where is the intake for the fans?**
A: These are pull fans (suppose you could turn it upside down to make it a push fan) the intake is on the bottom.  Imagine 2 fans in a rectangular chassis intake on one side exhaust on the other.

**Q: Is this supplied with a standard UK three-pin plug ?**
A: Hello,

Unit includes 110-220v AC/DC adapter (12v outlet) with US-style two-prong plug. The cord is about 4 ft long. The cooling fan will work fine if you plug into your system a UK 3-prong adapter for 220v 50hz mains.

Best Regards

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.

### ⭐⭐⭐⭐⭐ Perfect for cooling my Marantz pm7000n amplifier
*by M***R on 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!
