(Whole Product) PDF 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! Review: 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. ## 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 | |---------------|-------| | Customer Reviews | 4.6 out of 5 stars 1,124 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 ![AC Infinity, Speed Controller for One AXIAL Series Muffin Fan - Image 1](https://m.media-amazon.com/images/I/61wNZeYVULL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Superbly robust, effective and quiet *by D***M on November 23, 2018* I searched a good deal for a fan I could use at 18V or more, had trouble finding something to suit my parameters.

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.

Switch is worth while. ### ⭐⭐⭐⭐ Works best 1/2 and up *by T***N on January 27, 2024* 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. ## 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.de/products/4518324-ac-infinity-speed-controller-for-one-axial-series-muffin-fan](https://www.desertcart.de/products/4518324-ac-infinity-speed-controller-for-one-axial-series-muffin-fan) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-07-08*
