Compact 40mm server fan for dense chassis

The SXDOOL DFS402012H is a 40mm axial case fan built for server and workstation enclosures where space is limited. It runs on 12V DC power and draws 1.6W, making it suitable for 1U and blade-style systems that need directed airflow over CPU coolers or voltage regulators. The ball-bearing design targets continuous operation in rack environments.

Check 2-pin header and 20mm depth clearance

Verify that your motherboard or fan controller provides a standard 2-pin power header; the fan has no PWM wire, so speed is controlled by voltage only. Measure the mounting area to confirm 40mm square footprint and 20mm thickness fit without fouling nearby components or cables. Ensure the 12V rail can supply the 1.3W operating current for each unit installed.

Ball bearing maintains steady speed under constant

Under sustained load the ball bearing keeps rotational stability without the wear pattern seen in sleeve designs, so airflow remains consistent over long shifts. The non-LED black frame avoids light bleed in dense racks, and the 1.6W power draw stays flat during continuous 12V operation. Expect reliable thermal performance in always-on server duties.

Questions about this item

Does the 40 mm fan ship with screws or a mounting bracket, or must I supply them?

The listing only describes the fan itself — a 40 mm ball-bearing unit with a 2-pin power connector — so mounting hardware is not included and must be sourced separately.

The title shows 1.6 W but the specifications also list 1.3 W; which figure should I use when selecting a power header?

The supplier data gives both 1.6 W and 1.3 W; treat the higher 1.6 W value as the design maximum and ensure the 12 V header can supply at least that power.

Will the 12 V, 1.6 W rating deliver enough airflow for a typical 1U server chassis?

At 12 V the fan draws up to 1.6 W; actual airflow depends on the chassis restriction, but the ball-bearing motor is rated for continuous server duty at that power level.
