Dual 140mm USB Speed Control Fan, 5V Portable Cooling Fan for Flat-Screen TV Receiver Router DVR Playstation Xbox Computer Cabinet Cooler

Hooked them up to keep our sever rack cool.So far been running great and keeping stuff cool and air moving.

Have two of this dual set fan and likely to buy another in near future. Excellent keep you router or pc cool.

Moves air well. Could be a bit more powerful but it does the job.

My desk uses a tower compartment for the PC. It didn't have any air ventilation except the front door of the compartment. It would get so hot that I was worried it would melt stuff in the drawer right above it.I already had one small fan set with a temp controller that came from a different manufacturer. I was worried that they wouldn't move enough air to get the cooling I was after, so I bought these fans for additional flow.I removed the rubber feet, cut the proper hole, and mounted them to the desk. They daisy-chained right into my other fans and work great. My desk is cool once again and the stuff in my drawer is at room temperature at last.Oh, and these are very quiet too. I hardly notice them running and I have them set to HI.

Quiet is key on these. Installed in a cabinet in a conference room cooling an amplifier, and you can't hear them once you close the cabinet door. Can't hardly hear them unless you know what to listen for while the door is open. Made a HUGE difference in the heat dissipating off the amp. And no one can hear a thing during the conference calls!

This was the most minimal and effective way to make a cooling stand for an XPS 13. The USB powered, double fan connects to any USB power source. I connect to my dock and powers off automatically when disconnecting the laptop. There are two black brackets included to create a join between the two fans. I only used one at the front and at the back I used a zip tie. I also had some spare feet that I used to make it slightly taller. This creates space beneath to improve airflow as well as ability to use the space underneath the laptop if needed. You'll notice that I made mine a tripod / three legged design. This is mainly because the laptop is at the corner of the desk and that was what worked the best in my case. The other thing that has worked out nicely is that I now have the effect of the fans blowing across my desk, so keeps me cool too!

I use them outside on the patio for my receiver & i mounted one behind my tv since im in texas its get 5000 degrees down here in the summer. I plugged them into my tv usb so They come on when i turn my tv on.

This set was awesome and what I needed for a trip quality is good did what I needed to do..

Easily the best external fans I've ever purchased.They are quite and feel very high quality with their sturdy construction and considerations of a power supply and micro screw driver.

Los use en un gabinete donde tengo varios dispositivos electronicos y funcionan muy bien, no hacen mucho ruido incluso en la velocidad máxima, tienen buen flujo de aire.

VERY WEAK NOT I'M PRESSED AT ALL ON THE HIGHEST SETTING, It's VERY WEAK
