Can someone tell me how to connect 12v computer case fans directly to a external wall mount power supply in UK? Answered
I am building a laptop cooler/stand/usb hub for my GCSE product design coursework, and I am planning on using 2 of http://www.maplin.co.uk/Module.aspx?ModuleNo=45438 fans (12v). I want to connect them both to an external power supply, but the problem is that it uses a 4 pin connection if i'm right, I think it is molex? If I am not wrong, it has 4 cables, probably 2 black,1 yellow, 1 red. Which cables should I wire to where of an external power supply, an wall mountable would be the easiest. I live in UK so if anyone can give me any insight on where I can buy an external 12v power supply for the fan, please tell me!
