I have been using this cooling fan model for several years to keep me cool while I pedal on my bike desk (www.pedalpc.com). It's performed flawless, putting out a lot of CFM without a lot of noise for several hours a day, 7 days a weekA. I ordered two more for some other desks I am building, and was pleased to find the power cable is now longer, so I no longer need an extension cable!
