## Description

Dual ultra-quiet USB fans with multi-speed control and long-lasting dual ball bearings. Designed to efficiently cool electronics and components without excessive noise.

Review: Whisper quiet, very effective. - These are amazing little fans. Compact, whisper quiet, do exactly what they are designed to do. I originally wanted to buy slightly bigger versions and was concerned these wouldn't be strong enough, but they keep a 4-disk RAID and 2 other spinning disks cool, even on the lowest setting. On very hot days (e.g. 36°), I raise the speed from low to medium and that's enough to keep everything cool. Highly recommended.
Review: Chilly solution to a hot PS4 - With my PS4 in an IKEA unit ventilation has been a perpetual issue. I've even tried keeping the back of the unit facing outwards but with the new power supply on the PS4 Pro coming loose when you move the unit I needed a permanent solution that didn't require new units or major drilling of holes. For a low price I thought I'd give this unit a shot and so far I am more than impressed. Keeping it on Low or Medium my PS4 is now cool to the touch with one fan at the rear of the unit moving the air away and the other fan on top where it used to get hot. Even my wife with super hearing can't hear these two fans running when I'm playing now, and powered from the USB of the PS4 they just turn off and on with the console (check your settings to turn USB power off on standby). Definitely recommend this to any gamers with a cooling issue.

## 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

### ⭐⭐⭐⭐⭐ 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. 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.
