Delta 40 mm high-speed case fan

The SXDOOL TFB0412EHN is a 40 mm case fan built by Delta Electronics for server and workstation chassis. It targets builders who need concentrated airflow in tight spaces such as 1U enclosures, GPU coolers or small-form-factor power supplies. The three-pin connector provides basic speed reporting without PWM control.

26.03 CFM at 15000 RPM with 58.00 dBA

Double ball bearings sustain the rated speed while delivering 26.03 CFM of air volume for dense heatsink fins or restricted vent paths. Noise exceeds 50 dBA at full speed so the fan suits environments where acoustic comfort is secondary to thermal headroom. Continuous operation is rated for 10.0000 hours before bearing wear becomes a concern.

40×40×28 mm frame fits standard 4028 mounts

The 28 mm thick frame matches the common 4028 mounting pattern used in server blades and compact radiators. A 12 V 0.87 A draw requires a header or fan controller capable of supplying the current without voltage sag. No LED lighting or PWM wire is present, leaving the third pin for RPM monitoring only.

Questions about this item

Will the 3-pin connector on this 40mm fan work with my older motherboard that only has 3-pin headers?

Yes, the 3-pin connector fits standard 3-pin motherboard headers and draws 0.87 A at 12 V.

How can I verify the fan is running at the rated 15000 RPM after installation?

Use BIOS hardware monitoring or software such as HWMonitor to read the tachometer signal from the third wire and confirm speed.

Does the package include mounting screws or do I need to buy them separately for a 40 mm case opening?

The fan ships as a bare unit; four 40 mm mounting screws must be purchased separately.
