(Whole Product) PDF Review: 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. Review: 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! ## Features - Designed to control the speed of AC axial muffin fans rated at 100 to 125V AC. - Adjust your fan’s speed to optimize the airflow and noise for your application. - Features connectors that can be attached to one muffin fan’s terminals. - Includes wall-mount screws so you can secure the controller onto a flat surface. - Length: 6 Feet | Power: 50W or 0.4 A | Input: 100 to 125V AC | Output: 0 to 125V AC ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #310,352 in Home & Kitchen ( See Top 100 in Home & Kitchen ) #11 in Replacement Parts (Home & Kitchen) #2,196 in Household Fans | | Customer Reviews | 4.6 out of 5 stars 1,126 Reviews | ## Product Details - **Brand:** AC Infinity - **Circuit Type:** 1-way - **Connector Type:** Screws - **Contact Type:** Normally Open - **Current Rating:** 0.4 Amps - **Material:** Copper - **Operating Voltage:** 125 Volts - **Operation Mode:** manual - **Switch Type:** Rotary - **Terminal:** 2-pin ## Images ![Fan Speed Controller for 100-125V AC Axial Muffin Cooling Fans | Single Connector, for DIY Cooling Ventilation Exhaust Projects - Image 1](https://m.media-amazon.com/images/I/61wNZeYVULL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good purchase! *by J***G on January 3, 2019* Purchased a fan to install in a piece of furniture that we are using as a tv stand / stereo component cabinet.

Thank You! ### ⭐⭐⭐⭐⭐ Plug and play ready. *by M***E on December 30, 2019* I bought this unit with an infinity fan as well so I mount controller an extended distance from the fan and be able to turn it on/off without having to plug in and out of a socket. I could have spliced the wires to an extension cord with the switch or button but that seemed a little to ghetto for me when this was available. The controller plugs direct into the fan easily and your ready to go. It's also variable speed Low Med and High although the difference between them is very little. Overall it works for what I want it to do so I'm happy. ## Frequently Bought Together - AC Infinity, Fan Speed Controller for 100 to 125V AC Axial Muffin Cooling Fans, Single Connector, for DIY Cooling Ventilation Exhaust Projects - AC Infinity AXIAL 1238, Muffin Fan, 120V AC 120mm x 38mm High Speed, UL-Certified for DIY Cooling Ventilation Exhaust Projects - AC Infinity AXIAL 1225, Quiet Muffin Fan, 120V AC 120mm x 25mm Low Speed, UL-Certified for DIY Cooling Ventilation Exhaust Projects --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/4518324-fan-speed-controller-for-100-125v-ac-axial-muffin-cooling](https://www.desertcart.us/products/4518324-fan-speed-controller-for-100-125v-ac-axial-muffin-cooling) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-06*
