Quiet 80mm USB Fan, 5V USB Portable Cooling Fan for Flat Panel Xbox DVR PlayStation Router TV Receiver Computer Cabinet Cooler

I use it to get the heating of my wifi under control, it is good that I can connect it directly on the USB of the wifi and it work.

I zip tied it to to bottom of the upper rack in my RV refrigerator. Works perfectly, quiet, keeps food and drinks much cooler, and I don't lose valuable shelf space. Very pleased.

Just the thing! Had a router running hot, this little fan fit right underneath it and works like a charm! It arrived before expected in minimal packaging (a good," keeper" little box too). All good on this seller and this item.noise level less than the ceiling fan. Installation consisted of easily plugging it in to a cube, no vibration noticed, size is ideal, quality seems good as well.

I just bought a second one of these. I use it to cool an embedded server box I develop software for, that has to live beside my desk. The speed control is very helpful, when I am running a test on the system, I turn the fan speed up, then turn it down for normal idle operations so it isn't driving me crazy. At the medium speed, it does a fine job of keeping this box cool under all but the most CPU-intensive workloads and is barely noticeable.

I've had this fan running for awhile without any issues. Works great.

Arrived overnight. Wow !..got startred on my modification project right away in the morning. .turned out beautiful. The fan is as described. 3 speeds. Built actually pretty solid for a little fan..high speed moves a reasonable amount of air .I have mine set on low speed to start my heat tests. Installed the fan over 2 smaller heat sinks on top of a 100 watt led driver. It was running hot. Only using 80 watts . Would purchase again !

Very powerful little fan. I wish the cord was a bit longer but a great product.

Everyone says their fans are quiet, but these SCCCF fans are not. They are SILENT!I bought two, a 120mm fan for cooling a couple of 3.5 inch hard drives in RSHTech enclosures sitting on my desk, and an 80mm fan for cooling the flash drives plugged into an RSHTech 7-port hub also sitting on my desk. Since they sit on my desk, fan noise is annoying. Seated in my chair, I can't hear either one.Until I found these I had tried several fans by Gaiatop, Amken, and Sweetfull, searching for silence, to no avail.All of the fans have three speeds plus "off," however all but the SCCCF made audible noise even on the lowest speed. I operate both SCCCF fans on the middle speed.The SCCCF fans are no more expensive than any of the others, but have other advantages in addition to silence:1. All of the other fans must be manually restarted if power is interrupted. My computer powers them down at night, and these come right back up running when I reboot the computer.2. They claim to have "double" ball bearings with a service life of 65,000 hours (about 7 years). The other guys don't mention their bearings or service life, so they're probably just sleeve bearings.Disadvantage: The SCCCF fans are not really made for desktop use, so they have no tilt or pivot mechanisms. They just sit there on their quiet little rubber feet, blowing forward at my disks and flash drives. Not a disadvantage in my case.All of the fans require 5V USB power, and none of them come with a USB power supply.
