Project Information

This is a fan I made some time ago and I don't see that I posted it here. We needed fan that did not take a lot of power when we go dry camping with the motor home. I got this cheap 12v electronics cooling fan and built a case around it out of oak and put a switch and cigarette lighter plug on it. It runs good and is real quiet.

It is red oak and Z 120 stain and clear lacquered

Very cool. I wonder if you could run one of these from a USB port? I don't even know what voltage/current you can draw from a USB.

USB 2.0….5V-500mA
USB 3.0…5V-900mA

Missionworks, I'd worry about too much power drain through a USB for a motor driven item like a fan. The voltage posted would not run it anyway. They probably do that to limit it to powering miniature electronic circuits.
I amazed at what can be run through the USB all at once!!!!!!!!!!!! That must mean Universal… something or other… for all it does!...................Jim

Nicely done! I especially like that you've kept the fans in well, I ended up relying on double-stick tape 'cause I didn't plan ahead on my repurposing of computer fans.

Wow, Dan. I just looked at yours. It is whole lot cooler than the one I made. Nice job. Great minds think alike!!
You have a 3 stacker!!. I was thinking that if a guy made another one with 3 fans, they could be made to swivel to point in 3 directions at once!!............There's your challenge!!.................Jim

Nifty little cooling rig you got there!
Just a quick note for anyone wondering. USB contains a 5volt feed line that can be used to run electronic equipment. There are a number of 80mm and larger computer case cooling fans designed to operate on a 5volt circuit, so it would be pretty easy to build something like this that would plug into your USB port.

http://www.coolerguys.com/840556087908.html this fan actually moves 45.2 cfm at 5volts, it would be perfect for a computer desk fan!
Thanks for sharing.
Well done.
