Delta SFB0312H 12 V blower for tight chassis

The Delta SFB0312H is a 12 V DC blower that draws 2.00 A through a three-wire connection. Its 180 mm by 38 mm by 45 mm frame fits narrow enclosures where axial fans cannot reach. The unit spins at 6400 RPM to push 30.83 CFM through restrictive paths such as GPU shrouds or rack ducts.

30.83 CFM at 6400 RPM for focused airflow

At full speed the blower delivers 30.83 CFM, enough for concentrated cooling on a single hot component or short duct run. The 2.00 A draw and high RPM mean audible noise rises quickly, so it suits industrial or server builds rather than quiet desktops. Builders needing higher static pressure or larger volume should look at wider blowers or ducted axial arrays.

Questions about this item

Will the 12V 2.00A three-wire connector work with an older motherboard that only has a four-pin header?

The fan uses a standard three-wire 12V connector which fits a four-pin header; the fourth pin for PWM control will simply remain unused.

How can I verify the blower is reaching its rated 6400 RPM and 30.83 CFM after installation?

Use BIOS hardware monitoring or a utility like HWInfo to read the fan speed sensor on the third wire and confirm it reports 6400 RPM under full load.
