Compact 40 x 40 mm case fan

The CAFELE PSD1204PHB1-A is a 12 V, 2.9 W case fan built to the 40 x 40 x 15 mm footprint. It uses a three-wire connection for power and speed reporting. The small frame targets tight chassis, industrial enclosures or rack gear where larger fans cannot fit.

Replaces worn 40 mm three-wire units

Swap this fan in when an existing 4015-sized cooler becomes noisy, loses RPM or fails completely. The 12 V rating and 2.9 W draw match the original specification, so the upgrade is worthwhile only when the mounting holes and connector pinout line up with the legacy part.

Suits builders repairing small-form-factor

This unit fits maintainers who need a direct mechanical and electrical match for a 40 x 40 mm cavity. It does not serve buyers who want PWM control, higher static pressure or a larger frame for quieter airflow at lower RPM.

Questions about this item

Will the 40x40x15mm frame fit my case's 40 mm fan mount?

Yes, the fan measures 40 mm square and 15 mm thick, matching the standard 4015 mounting pattern used in many small-form-factor cases.

How do I connect the three wires to a 12 V header without reversing polarity?

Align the connector so the red wire goes to +12 V, black to ground, and the third wire to the tachometer pin; the keyed header prevents backward insertion.

When should I expect to replace the 2.9 W sleeve-bearing motor?

Sleeve bearings typically run quietly for several years; plan a swap when you hear a new rattle or see RPM drop below the rated speed.
