this system of fans will be blowing randomly on a piece of white silk with color full LED lights with the fans behind the silk. i want them to work from a computer power supply, although i would be open to other ideas(thank you for answering my poorly written question.)I need a lot of little computer fans for a sculpture,they need to be cheep what should i get and where?
A fan takes from 1 to 3 Watts. So any DC power supply would work, including just a plain old set of flashlight batteries. Red is hot or "+" on the wiring.
My suggestion is for you to go to a local mom and pop computer store where they fix computers and buy some generic fans made in Taiwan. They will run you about $2 a piece. If you don't want to do that, then you can pick from a thousand different choices on the net - here is an example from Newegg - note, they are more expensive, but there are tons of choices:
