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 £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 - Ultra-quiet UL-certified USB fan designed to cool various electronics and components. - Features a multi-speed controller to set the fan’s speed to optimal noise and airflow levels. - Dual-ball bearings have a lifespan of 67,000 hours and allows the fans to be laid flat or stand upright. - USB plug can power the fan through USB ports found behind popular AV electronics and game consoles. - Dimensions: 3.2 x 3.2 x 1 in. | Airflow: 26 CFM | Noise: 17 dBA | Bearings: Dual Ball ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00G059G86 | | Air Flow Capacity | 26 Cubic Feet Per Minute | | Best Sellers Rank | 4,489 in Computers & Accessories ( See Top 100 in Computers & Accessories ) 4 in USB Fans | | Brand | AC Infinity | | Compatible Devices | Desktop, Digital Video Recorder, Gaming Console, Receiver | | Cooling Method | Air | | Country Of Origin | China | | Customer Reviews | 4.5 4.5 out of 5 stars (35,130) | | Item Dimensions L x W x H | 25L x 80W x 80H millimetres | | Item Weight | 5 g | | Manufacturer | AC Infinity | | Material | Rubber | | Max Rotational Speed | 2000 RPM | | Noise Level | 17 Decibels | | Power Connector Type | USB | | UPC | 854759004327 | | Unit Count | 1.0 Count | | Voltage | 7.2 Volts | | Wattage | 1.1 watts | ## Product Details - **Brand:** AC Infinity - **Compatible devices:** Desktop, Digital Video Recorder, Gaming Console, Receiver - **Cooling method:** Air - **Material:** Rubber - **Maximum rotational speed:** 2000 RPM - **Noise level:** 17 Decibels - **Power connector type:** USB - **Product dimensions:** 25L x 80W x 80H millimetres - **Voltage:** 7.2 Volts - **Wattage:** 1.1 watts ## Images ![AC Infinity, MULTIFAN S1 Quiet USB Cooling Fan - Image 1](https://m.media-amazon.com/images/I/61yLtH6btDL.jpg) ## Questions & Answers **Q: Can this operate at low temperatures? I’m looking for a fan to circulate air in a fridge not to cool electrical equipment down.** A: I don't know but I'd imagine condensation would be a problem and if very cold, ice. I don't think the unit is sealed well enough against moisture. Maybe a unit which is meant to work underwater might be better **Q: Do I need to buy sticky feet for this product or will it remain still whilst I play on my ps4?** A: The rubber feet stop the fan's vibration through to the unit, and will stop it creeping or sliding, keeping it firm. Any further demands above this may require sticky feet. This is a great product which is close to silent in its operation. **Q: how long is the usb cable?** A: It's well over a meter. Somewhere between 1.5 and 2m. The connector to daisy chain along is about a 1/4 of the way from the fan. Good bit of kit, very quiet. Keeping my ex2 has drive at about 30 degrees, was getting really hot before. **Q: Can this be mounted easily into the back of a cabinet?** A: Depends what you mean by 'cabinet' & also on your competence level. Great little gadget and I use one of mine hung against an amplifier side vent via a hook made from a paper clip. Buy it, you will not be anything other than pleased. ## 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 S1, Quiet 80mm USB Fan, UL-Certified for Receiver DVR PlayStation Xbox Computer Cabinet Cooling - AC Infinity Turbo Fan Power Adapter, for MULTIFAN Series USB Fans - AC Infinity MULTIFAN S5, Quiet Dual 80mm USB Fan, UL-Certified for Receiver DVR PlayStation Xbox Computer Cabinet Cooling --- ## 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.pt/products/60449076-ac-infinity-multifan-s1-quiet-usb-cooling-fan](https://www.desertcart.pt/products/60449076-ac-infinity-multifan-s1-quiet-usb-cooling-fan) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-23*
