Compact 40 mm cooling for tight builds

The SXDOOL KDE1204PKVX is a 40 mm case fan built for small-form-factor enclosures, rack-mount gear or embedded boards where a standard 120 mm unit simply will not fit. It draws 1.4 W at 12 V and connects through a three-pin header.

Magnetic-bearing motor rated for 10 000 hours

The double ball bearing design runs at 8 200 RPM and delivers 10.8 CFM at a measured 27.5 dBA, so the single figure that decides fit is the 40 × 40 × 20 mm footprint — anything larger blocks adjacent slots or cables.

Short 8 cm lead keeps cabling tidy

The 8 cm cable reaches nearby headers without excess slack, and the bare three-pin connector works with any 12 V fan header that supplies speed sensing. No lighting, no controller and no adapters are included.

Questions about this item

How does the 8200 RPM speed translate to airflow inside a case?

The fan moves 10.8 CFM at 8200 RPM, delivering focused cooling for tight spaces like small-form-factor builds or component spot-cooling.

What does the 3-pin connector allow for speed control?

The 3-pin connector supports voltage-based speed regulation, so the fan can run quieter at lower voltages or at full 12 V for maximum airflow.

Will the 40×40×20 mm frame fit my mounting points?

It uses standard 40 mm square mounting holes with a 20 mm thickness, matching typical 4020 fan cut-outs on cases, heatsinks and GPU shrouds.
