Superbly robust, effective and 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!

Good purchase!
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.

Works best 1/2 and up
I am using this with a 2060 fan by the same manufacturer. It works the at 1/2 speed and up as below that the fan gets a little warm and a little noisy. The speed control is rated at 100w on the decal on the back which is different then the amazon specs. Perhaps it works better with a lower wattage fan. It still worked for my application though.

The perfect controller for AC Infinity Fans
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.

Turns my fans on
It looks good, excellent quality, will buy gain. I almost forgot what premium quality feels like. I got the 110 volt fan to go with it. I got the higher speed fan, it isn't quiet but puts out a lot of air, this keeps the noise down and tones everything to manageable degree. Not sure if this on a high speed fan is as quiet as the quiet model fan by the same company but is isn't bad at all. I can easily sleep with it on low. Switch is worth while.

AC Infinity Fan Speed Controller
Great fan controller for NAS server case. I have multiple fans running at varied times. Company has matching fans for these controllers.

It's okay
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.
