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

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%.

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 purchased both the AC Infinity Controller 1 and 2. I prefer the Controller 2, because it shows the temperature on a small display. However, if you just need to control the temperature, and don't need the display, then this is a great solution. It's inexpensive, and very effective. It's also powered via USB, so you don't even need an AC adapter. I would highly recommend this product.

I hooked the cooling fans on my entertainment center to this thermostat and works great

Love this fan, it runs in my cabinet and cools off my NAS drive, router, and switch. The thermostat is a bit slow to respond and it drops 5 degrees before shutting off. The bottom line is it keeps the temp at a safe point, just test to see which setting to choose to have it kick on at the temp you want. The number on the temp control is not what it kicks on at, because you can place the sensor close or far away from the hot item.

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 a couple sets of fans, one set for my receiver and another for my Xbox. Both in a cabinet so air flow is important. These just work - plug the controller into power, plug a fan into this (or fans in parallel), set the temp you want, and put the probe where you care about. Allows powering these from the wall but only running the fans when the devices are actually on. Great stuff.
