I use it to cool tp link deco be85 mesh wifi. the be 85 has inbuilt fans.however those fans were no good . I has to install this unit beneath each of those satellites . now never have had any reason to restart the mesh network. the medium speed is good in summer and I guess I can switch to low speed in winter to keep everything going. I the went ahead and bought the 2 fan version from same company to place under my virgin media hub 5 or 6 and the other end behind my tv ports unit. have had them for a months and I can say this unit is good quality. the power is supplied by usb a type plug which is connected to some usb a outlet on the powerstrips I have near appliances. the airflow is restricted unless you place something under the fan to raise it above around 1 inch above its plastic pucks to achieve silence and better airflow. it can not work with the plastic pucks alone. they will not let enough air flow beneath the fan to throw upwards. it needs clearance on at least the input side of 1 to 2 inches to achieve good blowing power. the 140mm size is good for be85 as it blows inside and around the body of the unit and man oh man is the tp link deco be85 big. so you can get an idea. it is as large as a 70kg persons thigh . so you get an idea that 140mm is a bit larger then a persons thigh . power consumption is ok however I didn't test it. seems the 2 fan 120 mm works as good as the 140mm single fan version. I would have preferred the 140mm version as it was single unit in comparison to the dual 120mm versions which I now have to place 1 below and 1 on top of the other be85 deco unit. definitely buy other stuff from this company . if you need an exhaust fan this is the company. if you need electronic cooling fan this is that company. they have a huge variety of stuff that carters to that class of people who we all hate however they are the ones making all the money after other bad businesses in the world. the 4 or 6 greatest money makers businesses right now running the world . and yes it definitely isn't owing a pizza chain or a restaurant or clothing store. Review: Well built and very quiet - Note: Product purchased directly from seller AC Affinity and fulfilled by desertcart. I use this to improve the air circulation on my Xbox One, which is housed in a narrow TV cabinet. Even though the cabinet is not fully closed, the external of the Xbox can get very hot, especially during a long session. I placed this fan directly on over the Xbox's top vents, blowing away from the xbox. The build quality is solid. You can shake it about, try to bend or squeeze it, there is no rattling or even creaking noise. Around the frame, all surfaces that you can touch, it is all smooth, no hint of any sharp edges. When the fan is running it is very quiet. There is a mechanical switch built into the USB cable. This switch has 4 positions; OFF, speed 1, 2 and 3. At speed 1, you wont even know it is running. Speed 2, in a room without any other sound you can almost hear it, but it is still quieter than my external Western Digital hard drive. Speed 3, well, you can definitely hear it. Not that the motor is noisy, just the wind noise it generated, and if you have the TV speaker on, it will drown out the noise from the fan. The OFF position is very useful, because I connected to the XBox usb port, and the port is always powered, even when Xbox is in standby/sleep mode. With the OFF position I can switch off the fan when I not using the Xbox. This is so effective, speed 1 is enough to keep the Xbox cool. The fan comes with 4 rubber feet attached, it does a very good job of keeping the fan on top of the xbox. At Β£15, this us not the cheapest 120mm fan on desertcart, but I am convinced this is worth its price tag. It is certainly has done what I needed it to do and quality is great. Only question is, how long will it last, time will tell. I would highly recommend this fan to anyone looking to improve air circulation for AV devices. ## Features - Quiet UL-certified blower designed to be placed on top of various electronics to draw out heat. - Features a multi-speed controller to set the fan’s speed to optimal noise and airflow levels. - Low profile design pushes air out the rear, ideal for applications with limited clearance. - USB plug can power the blower through USB ports found behind popular AV electronics and game consoles. - Blower Size: 4.7 x 4.7 x 1 in. | Airflow: 35 CFM | Noise: 17 dBA | Bearings: Dual Ball ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B012CL2V3I | | Air Flow Capacity | 35 Cubic Metres Per Minute | | Best Sellers Rank | 4,059 in Computers & Accessories ( See Top 100 in Computers & Accessories ) 2 in USB Fans | | Brand | AC Infinity | | Compatible Devices | Electronic components, Desktop computers | | Cooling Method | Air | | Country Of Origin | China | | Customer Reviews | 4.6 4.6 out of 5 stars (35,161) | | Item Dimensions L x W x H | 25L x 120W x 120H millimetres | | Item Weight | 8 Ounces | | Manufacturer | AC Infinity | | Material | Plastic Metal | | Max Rotational Speed | 2.5 RPM | | Noise Level | 17 Decibels | | Power Connector Type | 4-Pin | | UPC | 854759004495 | | Unit Count | 1.0 count | | Voltage | 5 Volts | | Wattage | 1.2 watts | ## Product Details - **Brand:** AC Infinity - **Compatible devices:** Electronic components, Desktop computers - **Cooling method:** Air - **Material:** Plastic Metal - **Maximum rotational speed:** 2.5 RPM - **Noise level:** 17 Decibels - **Power connector type:** 4-Pin - **Product dimensions:** 25L x 120W x 120H millimetres - **Voltage:** 5 Volts - **Wattage:** 1.2 watts ## Images ![MULTIFAN S2, Quiet 120mm USB Blower Fan with Speed Control, UL-Certified for Receiver DVR Xbox Modem AV Cabinet Cooling - Image 1](https://m.media-amazon.com/images/I/61Sa6CQkayL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: My S2 centrifugal fan is too noisy even on the lowest speed, I can hear a constant note from it. How can I run it slower than low?** A: You might be able to rig up a second speed switch in series with the first, which will have a subtractive effect on the voltage. I have two S2 fans in series, each with a speed setting switch, and the first switch affects both fans, the second affects only the second fan, which did indeed run slower as it stopped on lowest setting and is running (slower) on the mid setting. If it runs slower though, it may stop and it won`t be cooling much at all. Maybe the fan is in need of some TLC? Have you tried applying some lubricant to the fan, such as WD40 with added silicon? I am running 3 of these fans, on mid speed, and can`t hear them from 10 feet away. If the fan is just annoying you when whatever it is cooling is not on, then try plugging it into a USB that switches off when the gear is off. My TV and amplifier do that, only the Sky box leaves the USB power on all the time. Getting a second fan might allow you to run them in series with one running slower, or may demonstrate that your current fan is unusually noisy, in which case you already have a replacement. **Q: Do you get 1 or 2 fans in the pack?** A: This is a single fan in the S2 pack (I agree there are a couple of misleading photos showing use of 2 of them). Looks like there's a pair of fans in the S7 pack if you want two connected together from one power source. I have 2 S2 fans daisy-chained together powered by one amplifier`s USB outlet to cool itself and a separate power amp, so they only come on when the amplifier is on. **Q: How long is the usb cable?** A: Looking at it its 2M **Q: Which way is airflow** A: The fan picture shows the top of the fan. The S2 sits flat on the top of what you want to cool and it sucks air up out of what it is sitting on and blows the air out the rectangular port on one side. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The Real Deal 5/5 *by T***L on 14 July 2025* bought is companies stuff as it is designed for high end consumers. not us regular , rather the breaking bad type of high end consumers. hope you understand the analogy. so what is great. its quiet and high quality it will continue working without supervision especially if you are locked in or doing time. it will continue to work flawlessly behind your back and you don't have to worry about it. its silent and yes there is going to be some wind noise however there isn't going to be any whining noise.

I got this size for a specific cooling purpose, as it turns out it wasn`t needed but kept the fan anyway as it can be usd anywhere and for any reason. So useful - just plug it into any USB port or adapter and place wherever you need it. The rubber "all round" feet prevent vibration and movement, it can be used in any orientation and has 3 speeds + OFF altogether. Permanent or temporary placement - if you need something cooling, this is a very useful item to have. It`s reasonably quiet as well even on full - on low almost silent - at which I was a little surprised especially for the smaller 8cm size which can be a bit noisy. Cool a TV box, or portable hard drive, inside a PC for extra spot cooling, circulate the air in a cabinet.... you could even cool a hot pie off straight out of the oven if you wanted ! :) ## Frequently Bought Together - AC Infinity MULTIFAN S2, Quiet 120mm USB Blower Fan with Speed Control, UL-Certified for Receiver DVR Xbox Modem AV Cabinet Cooling - AC Infinity Controller 1, Thermal Trigger for AIRPLATE, MULTIFAN, USB Fans and Devices.
