SKU CH-5ZNV-524MW

A 40 mm square, 20 mm thick case fan with a three-wire connector and 1.4 W power draw

  • Compact 40×40 mm footprint fits tight builds
  • 3-wire connection enables speed monitoring
  • Low 1.4 W draw reduces power load
  • 20 mm slim profile suits shallow chassis

Compact 40 mm Case Fan

This 40 x 40 x 20 mm case fan uses a three-wire connection and draws 1.4 W. The KDE1204PKVX model is built for tight spaces where a standard 120 mm unit will not fit. It suits small-form-factor builds, rackmount chassis or replacement cooling in legacy hardware.

Direct 4020 Replacement

The fan matches the 4020 form factor so it drops into existing mounts without modification. The jump is worth it when a worn or noisy 40 mm unit needs a new, original replacement. Builders who need higher airflow or larger frame sizes should look elsewhere.

Highlights

  • Compact 40×40 mm footprint fits tight builds
  • 3-wire connection enables speed monitoring
  • Low 1.4 W draw reduces power load
  • 20 mm slim profile suits shallow chassis

Questions about this item

Will the 40 mm square frame with 20 mm depth fit my 4020 mounting holes?

The fan measures 40 by 40 mm and is 20 mm thick, matching the standard 4020 mounting pattern.

How do I connect the three-wire lead without reversing polarity?

Align the keyed 3-wire connector so the yellow signal wire sits on the motherboard header pin marked PWM or sense.
