  • Wide voltage range from 7.0 V to 13.6 V DC

40×40×28 mm Server Fan

The Delta FFB0412SHN-ROO is a 12 V DC axial fan built for server and workstation chassis. Its 4028 frame and double ball bearings target system integrators who need reliable spot cooling in dense 1U or blade enclosures. The three-wire PWM interface with stall alarm suits managed thermal loops.

43 CFM at 8700 RPM

Rated airflow reaches 43 CFM at 8700 RPM with a static pressure of 110 Pa, enough for restrictive heatsinks or tightly packed drive cages. Headroom narrows above 70 °C ambient or below 7.0 V input, where speed and pressure drop sharply. The 0.6 A draw limits use to 12 V rails with sufficient current capacity.

40 dB(A) with Stall Protection

Operational noise is specified at 40 dB(A) under normal load. The motor includes overload, reverse-voltage and rotor-lock protection, while the stall alarm signals failure before temperatures rise. L10 life is rated at 50,000 hours at 25 °C, supported by glass-fibre reinforced PBT housing and PA blades.

Questions about this item

Will the 40×40×28 mm frame and three-wire PWM connector fit the 12 V header on my older server board?

The fan uses a standard three-wire PWM interface and operates from 7.0 V to 13.6 V, so it will connect to a 12 V header and report speed via the tach wire.

How can I confirm the 8700 RPM speed and stall alarm are functioning once installed?

Monitor the tachometer signal through your server management software; a steady 8700 RPM reading and no stall-alert flag indicate normal operation.

Does the package include mounting screws or a power adapter, or must I source them separately?

Only the fan unit is supplied; mounting hardware and any wiring adapters are not included and must be obtained separately.
