SKU CH-B0KH-QRXKR

A 40 mm 12 V case fan drawing 1.3 W for compact chassis cooling

  • Compact 40 mm frame fits tight builds
  • 12 V operation matches standard PC headers
  • Low 1.3 W draw keeps power budget light
  • High airflow design moves more heat per revolution

Compact 40 mm 12 V case fan

The Fans KD1204PFS1 is a 40 mm square frame fan designed for tight spaces in small-form-factor builds or industrial enclosures. It runs on a 12 V supply and draws 1.3 W, offering a low-power option for targeted airflow where larger fans cannot fit.

1.3 W power draw defines its cooling ceiling

At 1.3 W the motor delivers modest static pressure suitable for ventilating a mini-ITX chassis, a network switch or a compact power supply. It will not move enough air for high-wattage CPUs or multi-GPU setups, so builders needing substantial heat removal should look for higher-wattage or larger-frame alternatives.

Questions about this item

Will the KD1204PFS1 12V 1.3W fan fit the 4010 mounting holes on my older case?

The 4010 designation matches the standard 40 mm × 10 mm frame, so it aligns with existing 4010 mounting points.

How can I confirm the KD1204PFS1 is spinning correctly after installation?

Check that the fan rotates smoothly and moves noticeable airflow at its rated 12 V / 1.3 W; a tachometer or motherboard RPM readout will show a steady speed.
