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! Review: Great Controller - Well worth the price! - 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. ## Features - Intelligent thermal fan controller with on-board processor and digital LCD display. - Controls up to six AC Infinity Cabinet and USB Fans, see below for compatibility. - Automated programming that self-adjusts cooling power in response to changing temperatures. - Features an alarm system, display lock, six fan speeds, two buffer options, and power failure memory. - Complete kit includes precision thermal probe, mounting screws, and power wall adapter ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00NG9TSG4 | | Best Sellers Rank | #277 in Computer Case Fans | | Brand Name | AC Infinity | | Color | Black | | Customer Reviews | 4.7 4.7 out of 5 stars (934) | | Display Type | LCD | | Item Dimensions L x W x H | 5.2"L x 1.1"W x 3.1"H | | Item Weight | 6.4 ounces | | Manufacturer | AC Infinity | | Material Type | Plastic | | Operating Temperature | 32 Degrees Fahrenheit | | UPC | 854759004402 | | Unit Count | 1.0 Count | | Voltage | 5 Volts | ## Product Details - **Brand:** AC Infinity - **Color:** Black - **Material:** Plastic - **Product Dimensions:** 5.2"L x 1.1"W x 3.1"H - **Voltage:** 5 Volts ## Images ![AC Infinity Controller 2, Fan Thermostat and Speed Controller, Controls AIRPLATE, MULTIFAN, USB Fans and Devices, for AV Cabinet Cooling - Image 1](https://m.media-amazon.com/images/I/51qsHxAlJOL.jpg) ![AC Infinity Controller 2, Fan Thermostat and Speed Controller, Controls AIRPLATE, MULTIFAN, USB Fans and Devices, for AV Cabinet Cooling - Image 2](https://m.media-amazon.com/images/I/61FaCX27x4L.jpg) ![AC Infinity Controller 2, Fan Thermostat and Speed Controller, Controls AIRPLATE, MULTIFAN, USB Fans and Devices, for AV Cabinet Cooling - Image 3](https://m.media-amazon.com/images/I/61-T-0x04wL.jpg) ![AC Infinity Controller 2, Fan Thermostat and Speed Controller, Controls AIRPLATE, MULTIFAN, USB Fans and Devices, for AV Cabinet Cooling - Image 4](https://m.media-amazon.com/images/I/61AGBCu9ruL.jpg) ![AC Infinity Controller 2, Fan Thermostat and Speed Controller, Controls AIRPLATE, MULTIFAN, USB Fans and Devices, for AV Cabinet Cooling - Image 5](https://m.media-amazon.com/images/I/61zG8G0sIXL.jpg) ## Questions & Answers **Q: Can you turn off the backlit LCD display?** A: Of course you can. You can turn it on permanently or off if you prefer. There are also three settings available for the brightness. **Q: What is the temperature buffer in regular operating mode - how far does the temp have to go up or down before the fan comes on or shuts off?** A: An additional note on this, AFAICT there is no temperature buffer in smart mode, it only applies in auto mode. In smart mode the fan just toggles on and off continuously as the temperature hovers around the set point, making that mode kinda useless. Reported as a bug to AC Infinity... **Q: Does the fan have auto mode to turn on automatically based on temperature?** A: It is not the fan that have an auto mode, it is the AC Infinity Controller. I leave mine on Smart program all the time so when the temperature rise up the fans start to extract the heat gradually and silently. The warmer the receiver the faster they go until the temperature comes down again ( according to your program ) and then the system turns off automatically. This is a fantastic product and seeing how hot the receivers can get I can only highly recommend AC Infinity. Before my receiver could heat up to 42 degree celsius, now the temperature never goes above 30 degree celsius. Hope that helps. **Q: What is the highest temperature you can set the fans to come on at?** A: Nvm...It looks like they've updated to a newer model than what I have. They claim the new model is: 32 to 140*F ## Customer Reviews ### ⭐⭐⭐⭐⭐ Near Perfection once in a while *by A***G on February 13, 2020* This is a perfect well designed device.

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. ## Frequently Bought Together - AC Infinity Controller 2, Fan Thermostat and Speed Controller, Controls AIRPLATE, MULTIFAN, USB Fans and Devices, for AV Cabinet Cooling - AC Infinity MULTIFAN S7, Quiet Dual 120mm USB Fan, UL-Certified for Receiver DVR PlayStation Xbox Computer Cabinet Cooling - AC Infinity MULTIFAN S5, Quiet Dual 80mm USB Fan, UL-Certified for Receiver DVR PlayStation Xbox Computer Cabinet Cooling --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/6270437-ac-infinity-controller-2-fan-thermostat-and-speed-controller-controls](https://www.desertcart.tw/products/6270437-ac-infinity-controller-2-fan-thermostat-and-speed-controller-controls) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-04-22*
