Delta EFB0405VHD 4020 5V case fan
The Delta EFB0405VHD is a 40 mm square case fan with a 20 mm thickness that operates on a 5 V supply drawing 0.50 A. It uses a three-wire connection for speed monitoring and is supplied in a 50-piece lot for server or workstation chassis cooling.
Check your chassis mounting pattern
Verify that the mounting holes match a 40 mm square pattern and that the chassis provides a 5 V three-pin header for each fan. Ensure the 20 mm depth clears adjacent components and cable routing. Buyers who need a different voltage, a two-wire fan, or a larger frame size should look elsewhere.
