While highly effective for privacy, this physical arrangement naturally traps a significant amount of heat around the equipment. I needed a robust, reliable cooling solution to prevent thermal throttling, and the AC Infinity MULTIFAN S1 has completely exceeded my expectations. Here is a breakdown of why this fan stands out: Build Quality & Material: Right out of the box, you can immediately tell this is a heavy-duty piece of hardware. It doesn't feel like a cheap, flimsy plastic PC fan. The housing is incredibly solid, and the dual-ball bearings give it a premium, durable feel that reassures you it can run 24/7 without burning out. Whisper-Quiet Operation: I am extremely happy with how quiet this fan is. A major contributing factor is the pre-installed silicone rubber feet on all four corners. They act as excellent vibration dampeners, meaning there is absolutely no annoying rattling or humming against the desk or the router itself. Airflow & Customizability: Despite its compact 80mm size, it moves a highly effective amount of air, easily flushing out the trapped heat and keeping my Wi-Fi equipment perfectly cool. The inline USB speed controller is a fantastic, convenient touch. Being able to toggle between High, Medium, Low, and Off without having to unplug the USB cord gives you total control over the noise-to-cooling ratio. Installation: It’s strictly plug-and-play. You just plug the USB into a standard power brick or an open port on your equipment, set it down, and you are good to go. The Verdict: If you have enclosed electronics, A/V receivers, or specialized networking setups that tend to run hot, this is a must-have. It’s a reliable, exceptionally quiet, and well-constructed fan that does exactly what it advertises. Highly recommended Review: Excellent fan, very quiet, fixed my slow/overheated PC issues - Excellent product. I was honestly not expecting something that works so well for so cheap. I have my surface pro 4 and dock stuffed into a slim drawer at work, it powers 2 4k monitors and does a LOT of heavy computing so it gets very hot, even the dock gets hot. Of course it doesn't help that it's stuffed into a drawer. It was to the point where the CPU was being throttled and everything was running slow as molasses, and probably causing long term damage as well. I cut out a hole the size of the fan, got some #8 32 2" machine bolts and lock nuts and attached it to the bottom of my drawer. The long bolts were so I could use the rubber mounts. The fan blows outward, there is plenty of air coming in around the drawer. I immediately saw a difference in performance, PC ran as it should be running. In terms of noise, there is none. My office is fairly quiet, but I can't say it's funeral parlor quiet, but still I can't hear any noise at all. The fan is solid, no rattling, no ball bearing noise, and this is at full speed. Air output seems excellent, I can feel a strong output at about 4 inches or so away. My surface pro is cool to the touch so I know it's doing it's job. I also like that it comes with a daisy chain output USB port, so you can daisy chain multiple fans. I initially thought it was a USB bypass, but it doesn't work with peripherals such as a usb mouse. In the instructions it only references it as a fan daisy chain. I'm completely happy, but if I had a wish list I'd say consider making this a usb bypass because usb spaces are highly limited on my surface pro/dock setup. My only caveat, but this isn't the hardware's fault, is that when my PC is locked the fan stays on. That's just how USB works. I'm in search of a program that can allow me to change the hours the fan runs, as I don't need it to run when the PC is locked as it's not being used heavily. I also cannot put the PC to sleep because I need remote access to it, although I have considered wake on LAN as an option. My concern is I don't know how long the fan will last being used 24/7 like this, but even if I replace it once a year it's cheap enough. ## 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 cfm | | Best Sellers Rank | #2 in Computer Case Fans | | Brand | AC Infinity | | Brand Name | AC Infinity | | Compatible Devices | Amplifier | | Cooling Method | Air | | Customer Reviews | 4.7 out of 5 stars 5,882 Reviews | | Item Dimensions L x W x H | 3.2"L x 1"W x 3.2"H | | Item Weight | 4.54 g | | Manufacturer | AC Infinity | | Material Type | Rubber | | Maximum Rotational Speed | 2000 rpm | | Model | AI-MPF80A | | Noise Level | 17 db | | Number of Items | 1 | | Part Number | AI-MPF80A | | Power Connector Type | USB | | Product Dimensions | 3.2"L x 1"W x 3.2"H | | UPC | 854759004327 | | Unit Count | 1 Count | | Voltage | 7.2 volts | | Wattage | 1.1 watts | ## Product Details - **Brand:** AC Infinity - **Compatible Devices:** Amplifier - **Cooling Method:** Air - **Material:** Rubber - **Maximum Rotational Speed:** 2000 RPM - **Noise Level:** 17 Decibels - **Power Connector Type:** USB - **Product Dimensions:** 3.2"L x 1"W x 3.2"H - **Voltage:** 7.2 Volts - **Wattage:** 1.1 watts ## Images ![AC Infinity MULTIFAN S1, Quiet 80mm USB Fan - Image 1](https://m.media-amazon.com/images/I/61CEC6Qw7yL.jpg) ![AC Infinity MULTIFAN S1, Quiet 80mm USB Fan - Image 2](https://m.media-amazon.com/images/I/715TZNiNZAL.jpg) ![AC Infinity MULTIFAN S1, Quiet 80mm USB Fan - Image 3](https://m.media-amazon.com/images/I/61937PlfmYL.jpg) ![AC Infinity MULTIFAN S1, Quiet 80mm USB Fan - Image 4](https://m.media-amazon.com/images/I/71Wzh47qmHL.jpg) ![AC Infinity MULTIFAN S1, Quiet 80mm USB Fan - Image 5](https://m.media-amazon.com/images/I/61-6CgQl2iL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent, Heavy-Duty Cooling Solution for Enclosed Network Gear *by S***_ on July 16, 2026* My home network setup includes a custom copper shield around my Xfinity router to minimize my wireless footprint.

The noise level is also quite good, on low its almost inaudible, on medium it is audible but realistically you won't hear it at even a short distance (a foot or two) high however is audible and can be heard from a distance, but audible does not mean loud, its still just a mild low hum, not annoying. As for feel in the hands it does not feel cheap, the plastic housing is thick and the grills are solid metal, even the rubber feet don't feel bad. They also have the ability to daisy chain so that you don't have to use up a bunch of usb ports if you use multiple (like me.) Overall these seem to be a great product, quiet, reliable, and well built. I do have one complaint though, they don't move a lot of air, yes the fan is small but an 80mm fan can easily move more air than this, however the amount of air it can move will usually be enough to cool something, as excessive heat is normally caused by stagnant air and this fixes that even on the lowest setting (for reference my tube amp ran at roughly 130-140 degrees F and even on low it drops temps to around 100 degrees F.) If you need a fan that moves a lot of air to cool an especially hot item, this is not what you should get, look elsewhere, otherwise 5/5. ## 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.sk/products/1168395-ac-infinity-multifan-s1-quiet-80mm-usb-fan](https://www.desertcart.sk/products/1168395-ac-infinity-multifan-s1-quiet-80mm-usb-fan) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-07-28*
