Controller 1, Thermal Trigger for AIRPLATE, MULTIFAN, USB Fans and Devices. Computer, AV Cabinet, Home Theater Cooling.

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.

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%.

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.

My AV receiver is located on the top shelf of a wooden built-in media cabinet. I have no doors on the cabinet, and any heat emanating from my AV equipment must vent through the front. My receiver sits on the top shelf and has about 4 inches of clearance above the cooling vents. However, heat used to get trapped between the top of the receiver and the top of the cabinet. Not anymore though! I placed a AC Infinity MULTIFAN S2 on top of the receiver vent and it blows all heat out the front of the cabinet. What I like about this fan is (i) it is well made, (ii) it has insulated rubber feet to isolate itself acoustically from the receiver, (iii) it has three fan speeds, (iv) its a blower configuration that blows the air forward vs. upwards, and best of all (v) it is very quiet. In the "Low" setting - which is sufficient for my needs - the fan's noise level is barely a whisper and cannot be heard across the room when all music is off. The fan is powered by USB or optional AC adapter. To mine I added a compatible thermal switch (the AC INFINITY CONTROLLER 1, Thermal Trigger) that activates the fan only when heat build-up exceeds a set point set by me. Once the receiver cools down after turning it off, the thermal switch turns the fan off via a small sensor placed on top of the cooling vents. The fan and thermal switch are connected by USB, and installation is straightforward and very easy. I highly recommend the fan, AC adapter, and thermal switch - the link for the fan follows: https://www.amazon.com/gp/product/B012CL2V3I/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1

I have purchased this multiple times because it is very simple to use. One button push configuration to determine one of 3 temperature settings with the 4th setting being on. I have not gone as far as checking the air temperature near the thermometer but it seems to work based simply on ambient temperature in the room where I have the device set-up. Of the three I have in use, they are still working and the oldest one is more than three years old in a home build electronics cabinet managing 4 fans. The second one is in a custom battery / solar generator managing a single fan and the third is mounted in a large solar generator managing 2 fans. I have had zero electronics failures.

nice to control s7 fan

I coupled this thing with a USB powered fan I installed in my media cabinet. My xbox was turning the cabinet into an oven. I was hoping the USB port on the game console would power on and off with the machine. This was not the case. not wanting to have the fan running 24-7, I bought this gadget. The way this works is you plug this into your USB port, you then place the thermostat wherever you want the temperature to be sensed, you plug your USB fan into the female USB port on the device, select a trigger temperature and then enjoy a nice and cool cabinet. The device is very well made feeling nice and solid. The temperature selection is done by press button which is nice and easy. It's working great and I'm quite impressed with it.

I am assembling a stereo system and required a cooling fan for a custom cabinet I built. My concern was cutting the hole into the cabinet without ruining the finish or showing any distress signs. I ordered the AC Infinity Controller 1, thermal trigger and AC Airplate S2 which fit best in the cabinet design. From opening the box to final installation, these products are first class. The boxing reminded me of when I bought my first Apple product - well packaged, insulated and a custom look that from first appearance made me feel happy about the purchase. Once opened, the instructions were detailed, clear and complete. Then I saw the clear plastic template provided for the cut-out. This isn't one of those dotted line, cut this out of the instructions template, but a separate plastic template for the cut out hole and face template for the Airplate S2 which made it EXTREMELY EASY to both mark the required cut out hole and place the face template exactly where I wanted it in the cabinet. First class engineering, thinking with the eyes of the customer. After installation, the Airplate S2 fan and thermal switch worked perfectly as described. The engineering of this product also allows for 3 additional fans to be added to the system and daisy chained to the original wiring via USB connection integrated into the fan design. I HIGHLY RECOMMEND these products, and if they are any indication of how AC Infinity designs all of their products, they would be recommended too.
