4 Pin Male to Female CPU Fan PWM Deceleration Cable Temperature Control Drop Speed Cord, Length: 10cm

1. Heat-shrink-wrapped package, 47Ohm resistance, all-copper high quality wire, environmental plug 2. Slow down the principle and effect: the fan in the power supply 12V DC series resistance, increase the size of the resistance in the circuit, to reduce the size of the current goal, to reduce the speed of the fan, concrete to reduce the numerical, according to the fan itself resistance is different, there will be different 3. 4 needle temperature control fan, use this speed line, can reduce fan speed, still can support PWM temperature control
