AC Infinity CONTROLLER 2, Fan Thermostat and Speed Controller, for Home Theater AV Media Cabinet Cooling

I use this to control 4 fans that keep the temperature down in a sideboard that houses my AV equipment. The sideboard is a mid-century G Plan thing that looks great but isn’t really suited to having a load of heat-producing boxes inside. I’d cut a sizeable hole in the back already but with the AV amp and an XBox running it soon got toasty in there. So I added a couple of 80mm fans... which helped, by it still got a little too hot. Next I added a couple of 120mm fans and this little controller. One of the bigger fans was cut into the rear of the sideboard and the other sits inside. Now the temperature perfectly controlled - the fans fire up when needed and the temp soon drops. The 120mm fans aren’t AC Infinity branded but work fine. The smaller fans are AC Infinity ones and noticeably better quality. Overall I’m very pleased with this - and the fans. A great bit of kit and a decent price. Top work!

This is a great fan controller with a good set of features. The text is white on a black background. Mine looked just like the one in the picture. I have connected 2 AC Infinity Fans to it and the system works great but plan oñ adding a 3rd which I have ordered. I have mine set to smart mode and have the temperature showing C not F. I set the temperature I want to maintain and put the controller into smart mode and it just works. I would highly recommend this controller.

Purchased this in conjunction with the S2 rear exhaust multi fans I got for my AV system. Although this is not fully compatible with the smart feature on this controller (for that you would need the S7 multifan top exhaust model) it will still run the fans and essentially shows the ambient temperature of your unit from using the built in sensor probe which has a fair amount of length to get to the desired resting place for the probe. My 250W mono block amps and processor was reading between 40-50 Celsius before I turned them on and after a while they controller unit was showing only 23 Celsius. Really happy with this control unit with it's great build and design, packaging and clear instructions manual not to mention the great customer service I received when trying to decide on certain factors of my set up at the time. Makes a refreshing change to find a product that is well thought out from start to finish and will be getting some more multi fans (S7 model that works with the smart mode on this controller) soon with another control unit to finish cooling down the rest of my system. keep up the good work AC Infinity!...

Superb controller. Mine is used in an AV cabinet on the lowest speed, which works perfectly and is near silent. Unable to obtain AC Infinity fans at a sensible price, but the coolerguys fans work fine. This is a much better controller than the CG version and cheaper.

Mine didn't come with USA to UK plug adaptor, you may wish to double-check with the supplier that they send this or a compatible PSU before purchasing as this will bump the cost up if you don't already have a spare adaptor. The unit itself does the job intended, but I question the cost when an equivalent PC fan controller costs a fraction of this price, though again you would need to spend additional money on a power source for that.

Mine looks different to the one in image but works well, I have 4 fans linked up to this controller and works perfectly. Nice and quiet too

great product , use it to keep my AV receiver cool in a bdi av cabinet , great features like smart mode that monitor temp and varies the fan speeds to maintain a constant temp in the cabinet, a great overall product and highly recommenced

Works perfectly with the AC S3 fans x2. Looks very smart and does the job well. I keep it on the smart function so it only engages the fans when the thermometer reaches my defined limit

Wonderful Design and silent. Though after many years I had to replace the unity as the LED backlight died Also this unit comes with USA plug only! The price is good in USA but once you add transport cost is too high for Europe

Works perfect!

almost great but one of the buttons for switching off the display has gone bad in a year

Excellent, running 6 small fans inside PC unit using this control. PC running most of the day for work and gaming.

AC Infinity hat ein sehr gutes Produktportfolio für die Kühlung von Geräten und Geräteschränken. Der Controller lässt sich so programmieren, dass er als P-Regler arbeitet, d.h. die Lüfterdrehzahl steigt langsam und proportional zur Innentemperatur im Geräteschrank an. Leider ist es aber keine PI-Regelung, was dazu führt dass sich in der Praxis ein Schwingen ergeben kann und der Lüfter immer wieder mal kurz anläuft. Bei niedrigster Drehzahl ist das aber nur hörbar, wenn es im Raum völlig still ist. Eine PI-Regelung wäre prinzipbedingt besser geeignet dieses Schwingungsverhalten zu vermeiden. Vom Design und der Verarbeitung her machen die AC Infinity Produkte einen sehr guten Eindruck. Leider gibt es viele Komponenten zur Zeit nur direkt in den USA (zum Beispiel über Amazon.com) zu bestellen, hoffentlich ändert sich dies bald. Es lohnt sich aber in jedem Fall die Preise in den USA zum Vergleich heranzuziehen, die Lieferung von dort ging eigentlich recht schnell und die Kosten sind überschaubar. Nur eine Rücklieferung ist unwirtschaftlich. Von mir für Design und Funktion die volle Punktzahl. Empfehlenswert!
