SKU CH-140J-WZVB0

120 mm case fan runs on 24 V DC with a 4-pin PWM connector for speed control

  • 24 V DC input suits industrial and server chassis
  • 5 A draw keeps power consumption low
  • 4-pin PWM header enables precise speed control
  • 120 mm frame fits standard case mounting points

120 mm 24 V PWM case fan

The P1238B24H is a 12038 frame fan designed for 24 V DC systems. Its four-pin connector enables PWM speed control for precise airflow management. The unit draws 0.5 A at full voltage. It fits standard 120 mm mounting points in server chassis or industrial enclosures.

12 W cooling capacity and limits

At 24 V and 0.5 A the fan delivers 12 W of cooling power, suitable for moderate CPU coolers or case ventilation. It cannot satisfy high-static-pressure radiators or multi-GPU thermal loads. Systems requiring variable-voltage 12 V operation or higher airflow ratings will need a different model.

Questions about this item

Will the 24V 0.5A 4-pin connector on this 12038 fan work with my existing 12V motherboard header?

This fan requires a 24V DC supply and draws 0.5A through its 4-pin connector; a standard 12V motherboard header cannot power it correctly.

How can I confirm the P1238B24H is spinning at the intended speed after installation?

The 4-pin PWM wire reports real-time RPM to the BIOS or monitoring software so you can verify the fan is running at its specified speed.
