## Description

desertcart.com: AC Infinity Controller 1, Thermal Trigger for AIRPLATE, MULTIFAN, USB Fans and Devices. Computer, AV Cabinet, Home Theater Cooling.

Review: Unit is great, but be sure your USB power supply is of reasonable quality - Thermal trigger worked perfectly for my application, controlling two 1W USB fans to cool a mini PC inside a wooden cabinet that was getting hot. Initially I thought the trigger was faulty because after cycling once it would power off and remain off. BUT I put a meter on it and found that my cheap USB power supply voltage was dropping to ~2v when the load cycled on, so the trigger would power down. I upgraded my power supply and the thermal trigger now works exactly as described. AC Infinity's tech support was responsive and helpful.
Review: Works as described.Tiny. - This is a great thermal temperature control trigger unit it's very efficient and accurate as per the temperature settings You set. It's also very small tiny it's approximately "1" W X 2 1/2 inches long much smaller than the specs provided here on the product page information. This little unit does a great job controlling my AC infinity fan that I'm using to keep a Wall plug power distributor that I have plugged into a surge protector cool from overheating. I use the digital version for my other AC infinity fans that are keeping my Denon AVR unit cool. Both of these thermal temperature control units do a fantastic job controlling the fans by the selected temperature settings it's a great investment to keep your expensive electronics cool. If you're debating about purchasing this product or any product from AC Infinity please be assured that they have very fine reliable products that are worth the money you pay for them, they're all of great build quality that's made to last. I highly recommend this thermal temperature control unit 100%.

### ⭐⭐⭐⭐⭐ Expensive, but does exactly what it is supposed to, and is utterly reliable
*by T***. on April 29, 2024*

Some background - I've been using AC Infinity products for 5 years (as of April 2024). They're great because the build great products that excel for the market they're intended to be used for. While the price is higher than their competitors, it is worth it. I purchased this temperature sensor for a niche purpose. I have a La-Z-Boy double recliner with a built-in armrest storage unit w/ AC outlets inside. It also has dual trays which are perfect for laptops. But I feared putting a 250 watt gaming laptop power supply in the storage unit due to the heat that it makes. To combat the heat, I purchased The AC Infinity Controller 1, and connected it to a set of dual 40mm fans. I also modified the back of the storage unit to accommodate the fans and am exhausting the air out of the back of the storage unit, instead of blowing air into it. This design is cool and efficient, and the Controller handles turning the fans on and off as desired. I also appreciate they programmed hysteresis into the controller so it doesn't constantly turn on and off at the target temperature. I don't have the # in front of me but I want to say it's 2-3 degrees F below the selected temperature. I'm incredibly happy with its design. It has worked as desired for about 2 months now, and I anticipate it will continue to do so for the foreseeable future.
