Heh, almost knew that answer but the problem is that i have 2 of these beasts and 1 is connected to CPU fan and other is connected to CHA 1 fan. They both work from CPU header, but i need to control them individually.
These things take power from 4-pin molex and control from pwm. This could be a problem as its just 2 wires, Fan PWM and Fan IN. it does not draw any current from Fan header.
12 Volts DC convenience: plugs into the computer power supply
Variable speed control via PWM thru the motherboard, from 1300 rpm for completely silent operation, to 4500 rpm for ultra high flow performance;
