Controller 2, Fan Thermostat & Speed Controller for USB Fans

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.

It does well to control the 6 fans I have running to cool my Xbox series x inside a small cabinet. I have 4 fans pushing air in the bottom of the cabinet and 2 fans running at the top. This keeps that cabinet under positive pressure and allows me to filter the intake so little to no dust enters the cabinet with my xbox. I also run the modem for my internet in this cabinet and the exhaust cools my router. I have smart settings adjusted so the fans kick on at 95 degrees F, and they run full blast at 105. This means the fans aren't on unless I have my Xbox running, and they don't ramp up until I am running a game that pushes the Xbox. For instance the fans never leave their lowest setting while I play my old school favorites, such as the original FFVII, and they begin pushing full capacity for new gen games. The temperature probe seems to be doing a great job hovering over the xbox's exhaust, and sends the right signals to allow my xbox to run full tilt, where I witness far less thermal throttling when pushing the xbox at peak settings. Placing the xbox in the cabinet with 4 fans below and 2 above has proven to be a significant upgrade to the xbox as it performs better than ever, and this controller is the heart of the whole system. Everything was simple to understand and this is a plug and play unit. As a bonus, the digital read out on top of my cabinet, serves to demonstrate I take my electronics, their functionality, and longevity seriously. I couldn't be happier with a basic order and a simple install that's made my xbox not only cool better, but allowed me to condition the air at the same time.

I recently upgraded my house to 10 Gb/s ethernet, and I discovered that high-speed networking equipment runs very hot. One of my Thunderbolt ethernet adapters kept overheating. I started looking into other adapters that might work, but I found Amazon reviews for nearly all of them that mentioned overheating. Apparently it's a common problem with 10 Gb/s ethernet adapters. Then someone in one of the reviews mentioned AC Infinity fans as a solution. I decided to buy the AC Infinity Controller 2 along with a 140mm fan. Wow this works great! I placed the fan next to my Thunderbolt ethernet adapter, and attached the AC Infinity temperature probe to the top of the adapter with some thermal tape. Now the fan turns on whenever the adapter reaches 90 degrees. I have the fan set to the lowest setting, and it's so quiet that I can't tell when it's running. I'm very sensitive to sound, and this doesn't bother me at all. However, it lowers the temperature quickly. What a perfect solution! Anyway, if you have hot electronics on your desk that need cooling, this is a perfect solution!

Installed this fan controller and two fan units to cool a cabinet containing a Denon AVR for a home theater. This was to replace a macgyver'ed PC fan system which was no longer getting the job done. The controller works very well - easy to set up and more eco-friendly than my previous setup. The screen is bright (but robo-dims when not in use) and in auto mode the fan shuts off when the temp in the cabinet drops to a configured threshold. Only wish is that the fans had a little more power - seems like the usb connection lowers the max speed. But I used two 80mm fan units (so four fans) and it does the job. The fans themselves fit well into the cabinet after cutting holes for the fans (template is provided) and the cables. They run quiet and the install looks professional. After this success, will be adding a similar setup to a second cabinet containing a Playstation.

I ordered two each of the double 6" fans, two each of the single 6" fans and two Thermostat controllers. One of the single fans and one of the double fans developed a sound that made me think they had a bad bearing. It was loud and obnoxious. So, you look at my 5 star rating and ask "Why 5 stars"? The reason is I called AC Infinity and they immediately took care of me, with apology. I ordered replacements off of Amazon and they promised to reimburse me. Moreover, they wanted the old fans back to try to figure out what root cause of the problem was. This curiosity means they care about quality. Thus far, I've had zero problems with the two other fans or the replacement fans. The controller units are very well designed and functionally work very well. The fans are also just as quiet as advertised (obviously once I got the bad ones replaced). One thing to keep in mind though when ordering fans though: Don't under order the number of fans. In a regular stereo (12 cubic feet) cabinet, I have a beefy receiver, cable box and blue ray player, I needed a 6" fan for every 4 cubic feet of cabinet space for the fans to keep up with the heat. A fan for every 3 cubic feet of cabinet space would probably have been even better. I don't blame the fans because in order for them to be silent, they can really only spin at a certain RPM. And, as I mentioned, they are silent. I'm a happy customer. If I have a problem develop with another bad fan, I'll update my review. Also, I have a product enhancement suggestion: It would be helpful to have a remote control that turns the back light on and off and allows me to adjust the temperature range. I would have paid extra for this capability.

Well, let me begin by saying that I typically try buy things from companies that I have had good experience with in the past. This is another example that where I’ve acquired this AC Infinity controller to install in my A/V media component cabinet to improve ventilation. I recently installed a few expensive A/V components and a media sever (NAS) in my cabinet. With the new arrangement, I noticed my NAS was reporting temps in mid-50 degrees Celsius, which was warmer than I had hoped. I then decided to install AC Infinity Fan controller and fans in the cabinet hoping the results would yield improved air flow. It looks very professional and worked very well. but not as much as I would like. I purchased the fan controller and 4 dual intake/exhaust fans. Positioned the two dual exhaust fans near the bottom on each side of the A/V media cabinet and two dual intake fans near the top on each side of the cabinet. I installed the controller on the top of the cabinet on the right side. This setup worked perfectly. Have a look at the pictures for the installation as well as at the temperature monitoring results of the NAS, which runs throughout the day and night. I am very please with the look and the performance.

Works perfect!

This is a very precise thermostat that adds to the complete set of blower options offered by AC Infinity. Very high quality built offered at a reasonable price. If you have a closed component rack, I highly recommend this brand of fan blowers for all your needs. I purchased their component style fans as well as some top or side mounted fans, all of which perform flawlesly. Noise levels are all dependent on the speed you use. I for one use them all at low speed and since they're thermostat controled, they will run a little more often but keep the noise to a level that won't protrude through the cabinet and into the room (during low level music passages for instance) If you found my review useful, please select yes below.

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.
