Use http://led.linear1.org/led.wiz to design your circuit
Source voltage is 12V for most computer fans
forward voltage = see spec sheet, 2-4 volts.
forward current will be on the led spec sheet - 10-20 ma
number of leds - thats up to you, probably 3 or 4 per fan.

Get some leds - scavenge or use example:

solder the leds together as per the plan from the wizard!
