How To Make a Computer Fan Run On Batteries Without a Computer

To power a computer cooling fan, using batteries, all you need is:

*A 9 volt battery
*Insulation tape
*9 volt battery snap, to hold the battery in place
*A wire stripper

1)Using the wire stripper, remove a sensible amount of insulation, from the wires on the computer cooling fan.

2)Once you have removed the insulation off the wires that are on the computer fan, twist the red coloured wire, from the fan, with the red wire, from the 9 volt battery snap. Apply this method for the negative wire as well, but instead twisting the black wires together.

3)Wrap the wires you have just connected, with insulation tape, to make connections more safer and secure.

4)Connect your 9 volt battery, to your battery snap and you computer cooling fan will operate.
