So I've asked some friends and searched this forums trying to figure out how to wire my fans to some old adapters I have lying around.
Based on what I know, there are 6 possible combinations for having a computer fan with a red, black, and yellow wire; as well as an adapter with a positive (non-marked) and negative (white marked) wire.
The combinations are as follows:
1. negative red + positive black
2. negative red/yellow + positive black
3. negative red + positive black/yellow
4. negative black + positive red
5. negative black/yellow + positive red
6. negative black + positive red/yellow
I've done this numerous times and each time with a 12v adapter and a 9v (the fans require 12v but I've heard that having less v just means it will run slower) and each time it hasn't worked at a all.
Can anyone help me? Are there any alternatives?
