DC 12V 3-wire server cooling fan

This Nidec A34861-58 GAMMA26 fan operates at 12 volts and draws 0.16 amps. It measures 50 by 50 by 15 millimetres and uses a three-wire connection. The unit is designed for server chassis airflow. It arrives in new condition.

Three-wire power limits speed control

The three-wire interface supplies power and a tachometer signal but does not accept a PWM control line. Voltage regulation is the only way to adjust fan speed. Builders needing four-wire PWM control cannot use this model. The 12V rating fixes the operating voltage.

Questions about this item

Should I pick the 12 V .16 A version or a different voltage for my server fan?

This cable is built for the Nidec A34861-58 GAMMA26 fan that runs on 12 V at 0.16 A, so match those ratings exactly.

What does the 3-wire layout actually do once the fan is installed?

The three wires carry 12 V power, ground and a tachometer signal so the motherboard can monitor the fan's 26 mm speed in real time.
