Compact 40 mm server fan

The OEM Industries 4028 1611FT-D4W-B86 is a 40 mm turbo fan built for server and workstation environments where space is tight. It targets system integrators and IT professionals who need a direct replacement for legacy NMB 4028 coolers in 1U chassis or dense rack units.

Ball-bearing thermals and 12 V 1.2 A draw

A ball bearing supports continuous rotation while the 4-pin PWM connector allows the motherboard to regulate speed based on temperature. At 12 V the unit draws 1.2 A, delivering focused airflow without LED lighting or extra wiring.

Sustained load in restricted airflow

Under prolonged load the turbo impeller maintains pressure across restricted fin stacks typical of compact heatsinks. The absence of a heatsink in the package means builders must pair it with a compatible cold plate, and the 40 mm footprint limits use to boards with matching mounting holes.

Questions sur cet article

How do I mount the 40 mm NMB 4028 turbo fan with its 4-pin connector?

Align the four screw holes on the 40 mm frame, secure the fan, then plug the 4-pin connector into the motherboard or server fan header so the PWM signal controls speed.

What maintenance will the ball-bearing 4028 fan need over time?

Ball bearings are sealed; expect only occasional dust removal from the blades and heatsink fins using compressed air.

At what point does the 1.2 A current draw become the limiting factor during continuous operation?

The 12 V, 1.2 A rating sets the maximum power envelope; sustained loads that demand more current will hit this electrical limit first.
