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

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!

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.

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.

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.

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

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.

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.

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.

Short story: In this video you can hear it on the lowest level with the door open. When I put it on the highest level and close the door. You can definitely hear it. It works great so far. Long story: I bought the AC Infinity AXIAL fan not realizing it didnt have a speed controller. So I bought the controller separately instead. I’m pretty sure you can find the fan and controller together for a reasonable price. I just didn’t want to go through the hassle of returning the fan and then buying the two things together. Anyway, I kept it on the lowest level all night. The cabinet door was closed - I barely heard it. I’m a light sleeper so I need this to be as quiet as possible if it is on overnight. Works great! I created my own FABRIKOR greenhouse cabinet this summer for my tropical plants that need moderate to high levels of humidity. I had everything I needed except for a fan for ventilation. So, I bought portable fans thinking those would do the trick. I was wrong. The two that I bought lowered the temperature and humidity levels. I decided leave it a without a ventilation fan. However, after 6-7 months the cabinet started to smell a little musty. I needed something quiet and small. Something that wouldn’t change the temperature or humidity inside the cabinet. Not sure if it’s a coincidence but it somehow increased the humidity. The mounting piece is not included. I bought it on Etsy - CADJungle.

Does exactly what it says it does. Built well. Finish was great. No burrs on the plastic. Yay!

This unit will allow speed control over AC Infinity AC powered fans, but the tradeoff is that at lower speeds, when you might hope for much quieter fan noise, there is some audible whine present because of how the fan speed is reduced. Bottom line is you can control the speed and the fan I'm using is quieter at lower settings, but it's nowhere near as quiet as the AC Infinity USB powered fans. That said, for my application, I frequently need the fan at full speed and appreciate the ability to control speed when desired.

I purchased this speed controller to help control a 10" Hurricane axial fan installed on a wood-burning furnace that is powered by an off-grid, solar-powered battery bank. I wasn't sure how loud the fan would be (if at all) and wanted the ability to control the speed and output if necessary. Installed the Hurricane fan and speed controller over the holidays. Both worked out wonderfully.

Used this to control the fan in my AV equipment It is from the same manufacturer so it eliminate the need for extra wits. It plugs directly into the fan base.
