Review: 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. Review: 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 - Length 6 FeetPower 50W or 0.4 AInput 100 to 125V ACOutput 0 to 125V AC - Designed to control the speed of AC axial muffin fans rated at 100 to 125V AC. - Features connectors that can be attached to one muffin fan’s terminals. - Includes wallmount screws so you can secure the controller onto a flat surface. - Adjust your fan’s speed to optimize the airflow and noise for your application. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00809BQZG | | Actuator Type | Rotary | | Brand Name | AC Infinity | | Circuit Type | 1-way | | Connector Type | Screw connection | | Contact Material | Copper | | Contact Type | Normally Open | | Control Method | Touch | | Controller Type | Mechanical knob | | Current Rating | 0.4 Amps | | Customer Reviews | 4.5 4.5 out of 5 stars (1,071) | | Item Weight | 0.01 Ounces | | Manufacturer | AC Infinity | | Material Type | Copper | | Model | AI-SC72A | | Mounting Type | Surface Mount | | Number of Positions | 2 | | Operating Voltage | 125 Volts (AC) | | Operation Mode | ON-ON-ON | | Switch Type | Rotary | | Terminal | Screw | | UPC | 819137020382 075239566160 | | Unit Count | 1.0 Count | | Wattage | 50 watts | ## Product Details - **Connector type:** Screw connection - **Contact type:** Normally Open - **Current rating:** 0.4 Amps - **Operating voltage:** 125 Volts (AC) - **Operation mode:** ON-ON-ON ## Images ![AC Infinity, AI-SC72A Speed Control Cord For 100 to 125V AC Cooling Fans - Image 1](https://m.media-amazon.com/images/I/61wNZeYVULL.jpg) ![AC Infinity, AI-SC72A Speed Control Cord For 100 to 125V AC Cooling Fans - Image 2](https://m.media-amazon.com/images/I/61ojKYc2U3L.jpg) ![AC Infinity, AI-SC72A Speed Control Cord For 100 to 125V AC Cooling Fans - Image 3](https://m.media-amazon.com/images/I/41Jl-zwHZhL.jpg) ![AC Infinity, AI-SC72A Speed Control Cord For 100 to 125V AC Cooling Fans - Image 4](https://m.media-amazon.com/images/I/61FqRTNYthL.jpg) ![AC Infinity, AI-SC72A Speed Control Cord For 100 to 125V AC Cooling Fans - Image 5](https://m.media-amazon.com/images/I/61T9gngmUCL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by S***A on 7 December 2023* Short story: In this video you can hear it on the lowest level with the door open.
