40 mm 12 V server cooling fan

The KDE1204PFV3 is a 40 mm square DC fan rated at 12 V and 0.8 W. It spins at 3500 RPM, moves 3.26 CFM of air and produces 19 Pa of static pressure. Noise is specified between 10 and 15 dBA. The frame measures 40x40x10 mm and connects via a two-pin power lead.

Suits tight server chassis needing low-profile

Buyers who require higher airflow or greater static pressure should consider larger frame sizes. The two-pin connector does not support speed monitoring or PWM control. Units weighing 20 g each are sold in pairs.

Questions about this item

What power header does this 12 V 0.8 W fan need on my motherboard?

It uses a 2-pin connector and draws 0.065 A at 12 V, so any standard 2-pin fan header rated for at least 0.8 W will power it.

How much quieter is the 11 dB(A) running noise compared with a typical 20 dB(A) 40 mm server fan I might keep?

The 11 dB(A) rating is roughly half the perceived loudness of a 20 dB(A) unit, making it noticeably quieter in the same chassis.
