Compact 40 mm server-grade fan

The SXDOOL TFB0412EHN is a 40 mm case fan built for tight server and workstation chassis. Double ball bearings and a 12 V, 0.87 A PWM motor target 1U racks, CPU radiators and power-supply retrofits where space is at a premium. Buyers needing larger airflow volumes or silent desktop operation should look elsewhere.

Thermals, noise and power

At 15 000 RPM the fan moves 26.03 CFM while drawing 0.87 A from a 12 V rail. Measured acoustics reach 58.00 dB(A), reflecting the high-speed profile required for dense heat loads. Rated continuous running time is 10 000 hours under load.

Build integration

The 4-pin PWM connector plugs directly into standard motherboard headers for speed control. Physical footprint is 40×40×28 mm with no LEDs, keeping cable routing simple in cramped enclosures. The supplier offers free re-termination to 2-wire, 3-pin or 2-pin interfaces on request.

Perguntas sobre este artigo

How do I install the 40mm 4-pin fan and what step is often missed?

Mount the 40 by 40 by 28 millimetre frame with four screws, plug the 4-pin connector into a PWM header, and enable PWM control in BIOS so the 15000 RPM maximum speed can be reached.

What maintenance or replacement will the double ball bearing fan need later?

The double ball bearings are rated maintenance-free for 10.0000 hours of continuous running; after that interval plan to replace the fan.

What limit appears first during sustained use at full speed?

At 15000 RPM the noise reaches 58.00 dB(A) and airflow is 26.03 CFM, so acoustic level is the first practical limit.
