AC InfinityMULTIFAN S1, Quiet 80mm USB Fan, UL-Certified for Receiver DVR Playstation Xbox Computer Cabinet Cooling

I purchased this item to use with a WD 8TB My Cloud EX2 Personal Cloud Storage NAS with WD RED inside NAS drive as I was worried about the temperature readouts even whilst idle. On the medium setting it has reduced the temperature of the two drives inside by an impressive 20 degrees. At this level the fan is just about audible but the noise is low and, importantly, not annoying in any way as many fans are prone to be. The fan is suitably powered using just one of the USB ports from the back of the unit.The fan arrived well packaged, appears to be extremely professionally manufactured and initial impressions suggest it offers great value at the price I paid.Will update in the future if anything changes.

Super little gadget that I`m surprised hadn`t been made available a LONG time ago.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 ! :)

I was actually a bit surprised by the quality of the item when I received it. I hadn't been expecting much since stuff like this is usually cheaply made but this is actually nice. The blade guards are metal, as is the central logo on each side. The rubber feet look like they will last and even act a but as suction cups on a flat surface. The lowest speed is more or less silent and the high speed is still fairly quiet. The thing even comes with a user manual. I'll also add that the controller stays relatively cool and the cable is nice and long.There is a USB extension for daisy chaining additional fans. It comes after the speed controller so those fans don't necessarily need a controller and, if they do have one, it won't be very useful.The blade guards and feet are removable, as one would expect.

I needed this to cool a cabinet which it does very well.. it's not totally silent - it's definitely audible even on low and I would have preferred a more linear control that let me go a bit slower. It's not unpleasant.. it's well designed.. just a minor niggle.It comes with 8 rubber feet that I couldn't see the use of (they're no use when the fan is attached to anything.. the screws aren't long enough to leave them on).

What a marvelous little fan. I use it under my 10gbe adapter which gets too hot to touch, and it keeps it completely cool on just the low setting.It is silent and very well made.You can't go wrong for a tenner.I'll be getting a few more of these in various sizes.

Nice to have three-speed options as the weather warms up I can adjust accordingly.Low and medium settings very quiet with high still acceptable. Nicely packaged and with a two-year warranty good value for a tenner. Get the feeling it might be working still in 10 years time ( let you know )

This is used in a camper van to assist in the extraction of heat and circulation of air around the pump as the internal fan has failed.It’s quiet enough to have running at night without impacting on sleep and is so much better than the original fan.Very well made and solid unit.

Works well on my Skywatcher 10'' Dobsonian telescope to cool down the primary mirror. Better value than Celstron's offering.
