AC Infinity, Fan Speed Controller for 100 to 125V AC Axial Muffin Cooling Fans, Single Connector, for DIY Cooling Ventilation Exhaust Projects

Using with a 120MM axial low speed fan on propane heater, Very quiet

I searched a good deal for a fan I could use at 18V or more, had trouble finding something to suit my parameters. Then I stumbled across the AC Infinity fan with the control box... VOILA! Problem solved! My power supply was having issues running my project AND my fan, this completely solved the issue by having the fan run on AC power from the wall, with a control box to regulate fan speed and thereby control my projects thermal issue and also keep it on the down low noise wise. I have to say, the robust aluminum construction is welcome, and the noise level, well, What Noise? It's so much quieter than the name brand computer fan I had tried that I'm "blown" away! :) Great work! Excellent fan, exactly what I needed. Thank You!

This is a great product that works well and is especially matched to Infinity fans.I was so impressed with the quality that is made into this control. The speed controller allows the smallest changes to fan speed allow the user to dial in a specific RPM to the attached fan. Worked so well for my project I am going to pick up another for a project in my RV.

It's alright. It's a basic fan speed controller, nothing special. A little over priced. I would have hoped for more. It does not do any kind of voltage regulation, and it's also kinda big.

I teamed this up with a two prong connector 120mm industrial fan that I repurposed from an IT cabinet. I then added a carbon filter to the front of the fan. I now have a variable speed soldering fume extractor that saved me a junk ton of money, and because of the free 120mm fan I acquired, works even better than any of the generic ones you find on Amazon.

I'm in the process of making a media cabinet. I know that some things lef off more heat and so I needed a way to remove the heat. I first picked up the Axial 1225 fan. I hooked it up and I found that while silent alone, mounting it to a wooden cabinet i build and then placing it in a wall there's a little hum from sligh vibration running full speed. So I picked this controller up. It fits perfect. There's enough wire on both ends (about 3' on both sides of the controller). I was able to hook this up, run the wire behind my box and back inside. Now the cabinet is silent and will be perfect.

Purchased a fan to install in a piece of furniture that we are using as a tv stand / stereo component cabinet. Needed the fan for heat buildup, but the fan is not tiny and was running full steam and quickly realized I should have purchased the controller when I got the fan. Controller arrived quickly, took less than a min to install and so far has been keeping the fan at a low rotation and it is therefore much quieter (can't hear the fan at all unless you get very close). Very happy with the purchase and have had no issues with variance in speeds as others have mentioned...mine has been holding steady for months now.

The Quality was good and looks like it will hold up well. Using it to cool an A/V system cabinet that gets hot. Works well, quietly and the variable speed adjuster allows you to turn the fan on and adjust the speed. I use it at half speed and it is nearly silent and pushes enough air for the job.
