Five 97 mm PWM blower fans for server chassis

This pack supplies five 12 V blower-style fans measuring 97 by 97 by 33 mm. Each unit draws 4.50 A through a four-wire PWM connector for speed control. The blower layout pushes air through restricted pathways typical of rackmount servers. Buyers needing quiet, low-pressure case fans for open desktop towers should look elsewhere.

Four-wire PWM control enables motherboard speed

The 4-wire interface lets the system adjust fan speed automatically based on temperature. Without PWM the fans would run at full voltage continuously. No other control method or voltage option is included in this pack.

Questions about this item

How much current does the 4.50 A rating actually draw when the fan runs at full speed in a live system?

The 4.50 A figure is the maximum rated current at 12 V, so each fan can pull up to that amount when the PWM signal commands 100 % duty cycle.

What does the 4-wire PWM interface control and what limits it in practice?

The fourth wire carries a PWM signal that tells the fan its target speed; the motherboard or fan controller sets the duty cycle, and the fan’s internal circuit caps the current at the 4.50 A rating.
