NMB 80mm four-wire server fan

The NMB 3110KL-04W-B56 is an 80 mm case fan built for Dell server chassis. It runs on 12 V and draws 0.3 A through a four-wire connector that supports speed reporting and PWM control. The 8025 frame size fits standard 80 mm mounting points in rack enclosures. This unit suits administrators who need a direct replacement for the original Dell cooling module.

Four-wire PWM limits

The four-wire interface allows the motherboard or fan controller to adjust speed and monitor RPM, but it requires a compatible PWM header to operate automatically. Without a PWM signal the fan will typically run at full speed, which may increase noise in quiet environments. Buyers who need voltage-only control or a three-pin connector cannot use this model without an adapter. The 0.3 A current rating also limits daisy-chaining multiple fans on a single header.
