40×56 mm 12V 1U server fan

This 40 mm by 56 mm centrifugal fan runs on standard 12 V power with a 10.8 V to 14 V operating range. It draws 1.70 A peak and 1.4 A at nominal voltage. The counter‑rotating dual‑motor design targets 1U server chassis and industrial cooling slots.

Counter‑rotating dual motor sustained airflow

Two brushless DC motors spin opposite impellers to maintain high static pressure across the full 16200 RPM range. The carbon‑brushless construction removes brush wear as a failure point. Rated maintenance‑free life reaches 10000 hours under continuous load.

40 mm square 56 mm deep form factor

The 40 mm by 40 mm inlet and 56 mm length fix the mounting footprint for 1U enclosures. No larger frame or alternative depth is offered. Builders needing a different height or screw pattern must select another model.

Questions about this item

How loud and hot does the DFPJ0456B2S get when running continuously at 16200 RPM?

The counter-rotating dual motor runs at 12 V with a 1.4 A draw and is rated for 10000 maintenance-free hours, indicating low power consumption and sustained operation.

What connector or mounting hardware must I already have to install this 40 mm × 56 mm fan?

The fan uses a standard 12 V DC supply within 10.8–14 V; ensure your chassis provides a compatible power header and 40 mm mounting holes.

Will this 1U server fan fit alongside older 4056-size fans in the same chassis?

Its 40 mm × 40 mm × 56 mm dimensions match the 4056 form factor, so it aligns with existing mounting points for that size.
