Jamicon 40mm micro server fan

The Jamicon KF0410B2H-R is a 40 by 10 millimetre axial fan built for 24 volt server and inverter chassis. It draws 1.2 watts through a two pin connector and uses a ball bearing for continuous duty in compact rack environments.

Replaces noisy 40mm sleeve bearing fans

Swapping a worn sleeve bearing unit for this ball bearing model removes rattling and extends service life in always on infrastructure. The upgrade is worth it when the existing fan develops vibration or fails to spin at full speed under load.

Two pin plug fits standard headers

Installation requires matching the red and black leads to the board header; reversing polarity will stop the motor. The 10 millimetre thickness fits most 40mm mounts but verify clearance against tall heatsinks or cable looms before securing the screws.

Questions about this item

Will the 40 mm by 10 mm frame fit my server cooler slot?

The fan measures 40 mm square and 10 mm thick, so it fits any standard 40 mm mounting pattern.

How do I connect the 2-pin 24 V lead without reversing polarity?

Align the red wire to the positive pin and the black wire to the negative pin on the 2-pin header; the connector is keyed to prevent reverse insertion.

When should I plan to replace the ball-bearing fan?

Ball bearings typically run for tens of thousands of hours; replace the fan if noise increases or airflow drops noticeably.
