Trying to mod my heatsink fan.

[moddedmatt]

So i bought an after market cooler with my cpu and i dont need the stock heatsink fan anymore.

I though "it could be a fun preject to make a portable fan out of it.

so i cut the fan out of the plastic mount and i cut off the plug.

I have a 9v volt battery mount which has 2 wires, 1 black and 1 red which are probably + and -, but for my cpu fan, i have 4 wires.

they are identified by the following:

yellow: +
black: -
green: S
blue: C

I tried connecting the black and yellow wires to the black and red from the battery mount and nothing happens.

is it because i need to do something with the green and blue cables or does this fan requires a fan monitor in order to work?

4 wire fan is pulse width modulated, not your typical dc motor. Up your voltage to 12 and it should take off.
