Controller 2, Fan Thermostat and Speed Controller, Controls AIRPLATE, MULTIFAN, USB Fans and Devices, for AV Cabinet Cooling

This is a perfect well designed device. It does exactly what I needed it for and is very simple to install, configure and operate. Once in a while -- some good stuff comes along that I simply have to rave about. This is one of them. It's simply an elegant solution. I'm using it to monitor and cool when needed a CCTV power distribution box with 9 cameras at 12 volts. The box has a transformer that has a built in fan that goes on when the transformer itself reaches 80 degrees f. The problem with the box design is that the transformers fan simply circulates the hot air within the box and relies on gravity to vent the hot air. Not very effective especially with limited vent openings no where near the transformer fan. This unit, combined with 2 USB fans is perfect to force the hot air out and to keep the transformer and wires from over heating. To see what it's doing, I've extended the probe and the USB line to over 40 feet away (using cat 7 cable) which works perfectly without any performance or accuracy degradation. Now, I can see the unit at the place where the CCTV is being monitors and not have to go the CCTV system to see what's going on. The only recommendation I'd make is that it would be SOOOOO nice to have multiple probes within 1 unit. I could use another probe (and fan) for the CCTV DVR itself and, while I'm at it, for my adjacent audio equipment and refrigerator. Now -- that would be AWESOME to have 3 or 4 probes with 3 or 4 separate USB outlets to serve multiple purposes without having several of these units cluttering up the desk top. In summary -- NICE unit -- well designed from a looks, software, and operations / configuration perspective. Kudo's to the engineer and manufacturer!

I have bought other fans from AC Infinity and found the quality excellent and price point good. I have used them for example - cooling my receiver when powered on. I like the fact that they come with blade guards and ball bearings instead of sleeves. So I decided to buy the fan controller and 4 more 120mm fans for my network rack. I kind-of went back and forth on whether to buy the controller because the price seemed a little high just to control the fans but decided to give it a try. Boy am I glad I did. I have had it now for over a month and I love this little fan controller. Here is the key point why I love the controller. It turns the fans off and on at a temp set point. Instead of running the fans continuously at a particular speed, the controller spins up the fans only when the set point is reached. So the controller stops the fans when they are not needed. Therefore, with the fans stopped, the air is not continuously bringing in dust, lint, no-see-ums. By running the fans this way, the whole rack is cleaner but still cool. I attached the temp probe to the top of my GS1900-16 switch because that component runs the warmest. The controller's four degree variation buffer is also great because it prevents the fans from turning on and off too quickly. I set the temp point to 85 degrees (I live in Hawaii). The fans start at 85 and continues to run until the temp drops to about 81. They remain off until the temp rises back up to 85. I run the fans at medium speed so the temp changes are gradual. Without the fans, the temps would rise to over a hundred. The digital lighted readout is also nice so I can check the temp and know why the fans are running or not. If you are considering this controller - do it. I very glad I did. AC Infinity provides good quality products. They are an excellent source for fan needs. Thank You AC Infinity.

AC Infinity AI-ATC, Fan Thermostat and Speed Controller, for Home Theater AV Media Cabinet Cooling Review This is one of the coolest gadgets that i have gotten. We had a propane fireplace with a wood surround mantle installed and it was blowerless. So we were trying to figure out how to get the air moving without to much work or noise. This works perfect when you use any of the AC Infinity fans. We used three of the AC Infinity AIRPLATE S3, Quiet Cooling Fan System 6" with Speed Control, for Home Theater AV Cabinets and linked them all together. Set the smart mode and made sure the thermal probe was where the heat would turn it on. They turn on and off by themselves and we don't have to touch them. Pro’s • Super simple to work and when using the AC Infinity fans its the perfect compliment • Quiet running • Includes thermal probe the mounting screws and a template as well with the power adapter • Digital readout and backlite as well Con’s • Not flush mount • When the fans are on high my dogs stare at them like they are aliens Conclusion This set up with the fans is the best for getting heat away from the fireplace without bunch of 120volt wires. Plugs and play for sure. There are multiple modes so you should mess with them and see what works best for you.

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

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!

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