Review: really nice quality, ideal for Biltong drying box! - These fans come really nicely packaged, good instruction booklet, and feel very professional. The grills look great and have a nice professional logo on. The variable speed is great - on the low setting they are silent, and barely audible on medium. on Hi you can here a feint whir if you are near, but if they are in a AV cupboard you won't notice. They shift a fair bit of air given the low USB power. I wanted a couple of fans to use on a Biltong drying box I was making. these fitted the bill perfectly. Powered by a USB wall wart I had lying around, one fan blowing in, one fan extracting, with variable flow. I removed the grills and rubber feet which are easy to do, and had to fit a different air filter, which is a shame given the nice appearance of the fans! They fill my purpose spot on, and I would highly recommend them as they are good value and nicely made/packaged. Review: Pure spectaculance - I'm very impressed with the quality of this product. It is very carefully packaged, albeit in plain cardboard, in a way that indicates a lot of thought has gone into this product from start to finish. The rubber feet work really well. The fans are smooth and quiet (but not silent - you can hear the air moving, for sure, but it's low volume). Connected to a Playstation 4 Pro, these keep the device cool in the cabinet and no noisy Playstation fans need to kick in, I have found. I might buy some more to have on my desk this summer, actually as my 6" desk fan sounds like a jumbo jet. By way of experimentation, they also worked plugged into a Panasonic TV and my laptop, as expected. I think the killer feature with these is the rubber feet, top and bottom. They work so well! ## Features - Ultra-quiet UL-certified USB fans 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. per fan | Total Airflow: 52 CFM | Total Noise: 18 dBA | Bearings: Dual Ball ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00IJ2J2K0 | | Air Flow Capacity | 52 Cubic Feet Per Minute | | Best Sellers Rank | 2,665 in Computers & Accessories ( See Top 100 in Computers & Accessories ) 9 in USB Fans | | Brand | AC Infinity | | Compatible Devices | Amplifier | | Cooling Method | Air | | Cooling method | Air | | Country Of Origin | China | | Customer Reviews | 4.6 out of 5 stars 9,961 Reviews | | Item Dimensions L x W x H | 8.1L x 2.5W x 8.1H centimetres | | Item Weight | 0.5 Pounds | | Manufacturer | AC Infinity | | Manufacturer Part Number | FBA_AI-MPF80A2 | | Material | Metal, Plastic | | Max Rotational Speed | 2.8 RPM | | Model Number | FBA_AI-MPF80A2 | | Noise Level | 18 Decibels | | Number of Items | 2 | | Power Connector Type | 2-Pin | | Power connector type | 2-Pin | | Product dimensions | 8.1L x 2.5W x 8.1H centimetres | | UPC | 854759004334 | | Unit Count | 1.0 count | | Voltage | 7.2 Volts | | Wattage | 1.1 watts | ## Product Details - **Brand:** AC Infinity - **Compatible devices:** Amplifier - **Cooling method:** Air - **Material:** Metal, Plastic - **Maximum rotational speed:** 2.8 RPM - **Noise level:** 18 Decibels - **Power connector type:** 2-Pin - **Product dimensions:** 8.1L x 2.5W x 8.1H centimetres - **Voltage:** 7.2 Volts - **Wattage:** 1.1 watts ## Images ![MULTIFAN S5, Quiet Dual 80mm USB Fan, UL-Certified - Image 1](https://m.media-amazon.com/images/I/61nvMZ0aiQL.jpg) ![MULTIFAN S5, Quiet Dual 80mm USB Fan, UL-Certified - Image 2](https://m.media-amazon.com/images/I/715TZNiNZAL.jpg) ![MULTIFAN S5, Quiet Dual 80mm USB Fan, UL-Certified - Image 3](https://m.media-amazon.com/images/I/61937PlfmYL.jpg) ![MULTIFAN S5, Quiet Dual 80mm USB Fan, UL-Certified - Image 4](https://m.media-amazon.com/images/I/71Wzh47qmHL.jpg) ![MULTIFAN S5, Quiet Dual 80mm USB Fan, UL-Certified - Image 5](https://m.media-amazon.com/images/I/61-6CgQl2iL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: If I turned one of the fans around would it act as an exhaust to remove the hot air from an enclosed cabinet? Thanks.** A: Yes indeed it would, the fans are completely reversible and can therefore be fitted either inside or outside the cabinet. I fitted mine inside as there was plenty of space behind the home cinema/DVD recorder units, and it works faultlessly on just the low speed in keeping them cool. **Q: Will these fans work for 2 consoles on the back of av cabinet as an exhaust using a usb y splitter for power? to both?** A: These fans have are hard-wired together. With the option to days chain another set as they have a female USB in lime as well. They have three speeds. **Q: I have a water cooled gaming pc under my desk and need a fan to give air flow on top of my pc is still powerful enough.** A: Providing there is somewhere for the air to go (i.e. the PC is not completely closed in) and not knowing how hot it gets on top of your PC, I would have thought so. They are great fans, especially if you get AC Infinity temp/thermostat control switch so it kicks on when the temp exceeds a preset threshold. They do bigger USB fans, I think the next one up is 120, if you want a step up. I personally think they are the best USB fans for a good balance of power and quietness. **Q: How much power do these consume?** A: sorry I really don't know, but they do work well ## Customer Reviews ### ⭐⭐⭐⭐⭐ really nice quality, ideal for Biltong drying box! *by J***N on 9 May 2017* These fans come really nicely packaged, good instruction booklet, and feel very professional.

I have one blowing air down on the power supply and the other taking the hot air up and out. They have a switch for the speed of the fan low,medium and high, low speed is very quiet the medium is quiet too but on high you can hear it on low volume tv or in between adverts when it's quiet. I set it to medium and on low volume tv or bluray or cd you cannot hear it at all. Before I bought these my amp got very hot after a few hours on a night but now with the fans on medium it's cut the heat down by half, Iv always said if an electronic product like an amp or laptop runs hot it won't be long before you start having problems with it. ## Frequently Bought Together - AC Infinity MULTIFAN S5, Quiet Dual 80mm USB Fan, UL-Certified for Receiver DVR PlayStation Xbox Computer Cabinet Cooling - AC Infinity MULTIFAN S7, Quiet Dual 120mm USB Fan, UL-Certified for Receiver DVR PlayStation Xbox Computer Cabinet Cooling - Govee Hygrometer Thermometer H5075, Bluetooth Indoor Room Temperature Monitor Thermometer with Remote App Control, Notification Alerts, 2 Years Data Storage Export(Only Supports 164ft Bluetooth Range) --- ## 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/47946707-multifan-s5-quiet-dual-80mm-usb-fan-ul-certified](https://www.desertcart.us/products/47946707-multifan-s5-quiet-dual-80mm-usb-fan-ul-certified) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-05*
