Compact 40 mm axial case fan
The 109P0412G3D073 is a 12 V DC axial fan measuring 40 by 40 by 28 mm. It draws 0.31 A through a three-wire connection and is designed for 1U server chassis or other space-constrained enclosures. The unit is supplied new and ready for installation.
Suited to tight 1U builds
This fan fits builds that need a low-profile 4028 frame with a standard three-wire header. Buyers who need PWM speed control or a different voltage should consider other options. Builders requiring larger frame dimensions or higher airflow ratings will need to look elsewhere.

Questions about this item
What power connector does the 109P0412G3D073 fan need?
The fan uses a 3-wire connector that plugs into a standard 12 V fan header on the motherboard or a fan controller.
Will the 40 mm square frame fit in the same 1U rack slot as my older 4028 fans?
Yes, the 40×40×28 mm dimensions match the 4028 form factor, so it occupies the same 1U space as existing fans.
