40 mm 12 V case fan for tight spaces

The Fans AFB0412LB is a 40 mm square frame fan with a 15 mm thickness. It runs on 12 V and draws 0.09 A through a three-wire connection. The compact footprint suits server inverter units or small-form-factor chassis where larger fans cannot fit.

Suits builds needing a single 40 mm replacement

This fan serves technicians restoring original cooling in legacy server gear or compact enclosures designed around the 4015 form factor. Builders who require higher airflow, PWM speed control or a larger frame should look elsewhere.

Questions about this item

What voltage header does the AFB0412LB 40 mm fan need on my motherboard or controller?

The AFB0412LB runs on 12 V DC, so it requires a standard 12 V fan header or a 12 V power source with a matching three-pin connector.

Will the 40 mm frame and 15 mm thickness fit in the same mounting holes as my existing 40 mm fans?

Yes, the fan measures 40 mm square by 15 mm thick (4015 form factor), matching the standard 40 mm mounting pattern used on most server and inverter chassis.
