After the remodel we wanted a better solution than using an older Dell PC which was using up precious desk space. We purchased an Intel W5 Pro with an Atom x5-z8350 & 2GB of Ram running Windows 10 Pro. As we just needed it to display a web browser we felt this solution which would free up space as well should do the job.After a few months of 24/7 operation I noticed the fan was starting to fail and temps started to rise. Finding the actual replacement fan didn't seem to be an option due to how proprietary the little fan was. Looking for a USB powered alternative I stumbled across this, took off the case on the W5 and strapped it to the top.Ugly? Sure, but as you can see adding the fan brought temps down from 70/80c to 36c!! With averaging around 55 or so with a moderate work load. As far as acoustics it's fairly silent on the lowest fan speed setting. I experimented with turning the speed up but didn't make that much of a difference. So keeping it on the lowest setting is best.The monitor has a USB port where it pulls power and the nice thing is that it will go to sleep when the monitor does. It is not connected to the compute stick as I didn't want to stress the little device any further.So... great little fan for 10 bucks. Moves a good amount of air, is quiet and has 3 speed settings. I highly recommend it. ### ⭐⭐⭐⭐⭐ This Fan Will Make Your Electronics Last Longer! *by on Reviewed in the United States September 26, 2018* This isn't the first AC Infinity fan I've bought. On electronics that put out alot of heat, quite often the manufacturer doesn't provide for adequate ventalation so you have to replace your equipment more often, and they make more money. These fans help to remove that electronic destroying heat and extend the life of your investment! I used this particular fan to cool my D-Link Router, which puts out alot of heat, but yet has no cooling fans. Because of the small size of this AC Infinity fan, it is perfect for the improved removal of heat from the router. Plus, since it sets adjacent to my computer, there are plenty of USB ports handy. In the past I have also used AC Infinity fans for cooling my TiVo Bolt and my television. The fan is described as ultra quiet, which I feel is an exaggeration. It's quiet, but not ultra quiet. If I had one complaint, it would be that the cord is so long for MY router application. It would be nice if the cord length was adjustable. This item is designed in California, but it's MADE IN Communist CHINA. Despite being made in China however, the quality seems to be very good. I recommend this item. ### ⭐⭐⭐⭐ If you mount these to eyeglass frames your eyes don't sweat. *by on Reviewed in the United States February 24, 2019* OK the serious stuff. They provide a cooling solution for NVMe external enclosure heatsinks. Also they work other vented storage enclosures you can find on Amazon.com that lack active cooling. They work well as do all of the AC Infinity Cooling solutions. They are high quality compared to other choices. The fan impeller is quiet and you can adjust the speed for near silent running characteristics.Test Images:40mm AC Infinity fan unit set to High.Raid Mini enclosure with two Seagate FireCuda 2 TB hardrives.Acoustic emissions very close field measurement. Rating: Office environment and below normal conversation levels.Second measurement-Relative Ambient sound levels about four feet away from test rig and two feet from four-120mm case fans. Rating-Quiet living room.Differential Acoustic Results:17.3 db...of course who sits with their ear on the fan except people whom mounted their fans to eyeglass frames.I think the inline stringing feature which allows you to chain additional fans together is just too cumbersome in this instance due to the weight of the fan itself. Instead it would be nice if this portion of cabling came terminated at each end so you could remove it and plug it back inline as needed. Also when using a USB Hub as a power source where the device that needs cooling is close, 8"-18" max inch's in lead length would work better than the wire bundling requirement with the current configuration. ## Frequently Bought Together - AC Infinity MULTIFAN Mini, Compact 40mm x 20mm USB Fan, UL-Certified for VR Gear, Aquarium, Roku, Router, Raspberry Pi, Cosplay, Helmet Cooling Ventilation - 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 --- ## 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.com.my/products/63275470-ac-infinity-multifan-mini-compact-40mm-x-20mm-usb-fan](https://www.desertcart.com.my/products/63275470-ac-infinity-multifan-mini-compact-40mm-x-20mm-usb-fan) --- *Product available on Desertcart Malaysia* *Store origin: MY* *Last updated: 2026-08-15*
