Review: Great fans that work with a great customer service. - To start of with I done my research after stumbling upon these cooling fans to cool down my AV system consisting of 250W mono block amps a dual processor which runs as hot as the amps as well a Sky box and PS 3&4 that run hot. I still had unanswered questions though so contacted AC Infinity's customer service to determine which type of fans suited my needs best. What can I say the customer service and helpful punctual reply's are second to none and wish all company's had this level of helpfulness & patience with all the questions I kept asking over several emails! Thanks Tommy for the invaluable advice anyway ; ) As for the product in hand that I purchased I went with the rear exhaust blowing S2 fan unit as my shelf gaps are quite narrow between each other so could not have the top exhausting S7 fan units the way my system is set up. Got to say the packaging is simple, yet smart with well thought out packing design and protection. Once open it comes with a clear and concise instructions manual that has been written by a human who knows his stuff and not a robot that has then translated from Chinese to English. The fan unit it self is well built and has a great feature of been able to daisy chain these fans together so less usb ports are used to power them. The fan unit itself is fairly quite unless on the highest speed you can detect the sound but is only noticeable when it is quite in the room, I say this but have to note I am running Four of these in tandem at the moment so the noise is a cumulative sound of all four fans running on highest speed. I have also purchased the Fan thermostat thermal & speed controller AI-ATC which has a temperature sensor probe attached and which measures your hottest area of a piece of kit and my amps were running at around 40-50 celsius in fairly warm ambient temperature has been quite a hot summer anyway and with the fans in place has cooled my amps and processor down to between 21 & 24 Celsius which makes the top of the units feel nice and cool. before the arrival of having these fans my amps and processor felt so hot to touch It felt like I could cook some bacon and eggs on top of them but with the S2 fans they are almost cold to the touch. Only note for these S2 Rear blowing models is unfortunately they are not fully compatible with the smart mode of the thermostat & speed controller like the S7 top blower fans are but does still work and can be adjusted manually on the controller. Over all the S2 fan does what it says on the tin or cardboard packaging in this case and cools my Hifi equipment right down to a sensible temperature that is not going to frazzle the electronics. Can't rate these enough from the fan itself with the build and design to the great customer advice I had from these guys. Looking forward to getting an Aircom T8 next and some more mutltifans soon from AC Infinity.
Review: Great Cooler - Has cooled my AVR to acceptable levels. Have added the 2nd to increase the cooling by even more. Used the blower fan as limited top space on my Denon X3800H. the sides do have space around them and the cooler air that gets sucked in through the sides (as the fans suck out the hot air over the heat sinks) has cooled the rest of the AVR.

## Features

- Quiet UL-certified blower designed to be placed on top of various electronics to draw out heat.
- Features a multi-speed controller to set the fan’s speed to optimal noise and airflow levels.
- Low profile design pushes air out the rear, ideal for applications with limited clearance.
- USB plug can power the blower through USB ports found behind popular AV electronics and game consoles.

## Questions & Answers

**Q: Can this operate at low temperatures? I’m looking for a fan to circulate air in a fridge not to cool electrical equipment down.**
A: I don't know but I'd imagine condensation would be a problem and if very cold, ice. I don't think the unit is sealed well enough against moisture. Maybe a unit which is meant to work underwater might be better

**Q: Do I need to buy sticky feet for this product or will it  remain still whilst I play on my ps4?**
A: The rubber feet stop the fan's vibration through to the unit, and will stop it creeping or sliding, keeping it firm. Any further demands above this may require sticky feet. This is a great product which is close to silent in its operation.

**Q: how long is the usb cable?**
A: It's well over a meter. Somewhere between 1.5 and 2m.  The connector to daisy chain along is about a 1/4 of the way from the fan.  Good bit of kit, very quiet. Keeping my ex2 has drive at about 30 degrees, was getting really hot before.

**Q: Can this be mounted easily into the back of a cabinet?**
A: Depends what you mean by 'cabinet' & also on your competence level. Great little gadget and I use one of mine hung against an amplifier side vent via a hook made from a paper clip. Buy it, you will not be anything other than pleased.
