SKU CH-E0F5-9C1R5 MPN EFB0412HHD

A 4020 12V case fan with double ball bearings, 8200RPM speed, 9.43CFM airflow and 30.5dBA noise

  • 12 V DC power with 0.15 A draw keeps energy use low
  • 8 200 RPM double ball bearing spins for strong airflow
  • 43 CFM air volume clears heat from tight switch chassis
  • 5 dBA noise level runs quietly in rack environments
  • 10 000 hour rated life at 25 °C reduces replacement frequency

40×40×20 mm 12 V case fan

The SXDOOL EFB0412HHD is a 4020-size DC fan rated at 12 V and 0.15 A. Double ball bearings and a stall-alarm signal wire target network switches, firewalls and similar rack-mount gear that monitor fan health. It delivers 9.43 CFM at 8 200 RPM while drawing 1.8 W.

Replaces failed OEM 4020 fans

Designed as a drop-in replacement for H3C 3600, 5600, S3100-52P and comparable Delta-equipped units where a dead fan triggers an "F" status or "Fan 1 Failed" log entry. Swapping the unit restores normal status indication without firmware changes. The three-wire connector matches the original pin-out; re-pinning is only needed for non-standard headers.

Sustained 10 000-hour rating at 25 °C

Rated for 10 000 hours of continuous operation at 25 °C and 45–85 % relative humidity. Double ball bearings maintain consistent speed and noise (30.5 dBA) over that period without lubrication intervals. The stall alarm provides early warning if airflow degrades under prolonged load.

Questions about this item

Will the 40x40x20 mm frame fit the fan tray of an H3C 3600 or 5600 switch?

The 4020 dimensions match the original Delta fan used in H3C 3600, 5600 and S3100-52P units, so it slides into the same mounting holes.

Which wire goes to which pin when I swap the connector for the stall-alarm header?

Black is negative, red is 12 V positive, and white carries the stall-alarm signal; match them to the board's pin-out before powering on.

How long before the double ball bearings need replacement in a 25 °C rack?

Rated service life is 10.0000 hours at 25 °C and 45-85 % humidity, so plan a swap around that interval.
