Zyvpee AD0412UB-C56 40mm 12V 0.14A 3 Pin case fan

Compact 40 mm case fan

The Zyvpee AD0412UB-C56 is a 40 mm square frame fan with a 20 mm thickness designed for tight chassis spaces. It runs on 12 V power and draws 0.14 A through a standard three-pin connector. The ball-bearing motor targets CPU cooling duties in small-form-factor builds. No LED lighting is fitted.

Check connector and clearance

Verify that your motherboard or fan controller offers a free three-pin header before ordering. Confirm the mounting holes match a 40 mm by 40 mm pattern and that at least 20 mm of depth is available inside the case. The fan has no PWM wire so speed control depends on voltage regulation from the header.

Fits small-form-factor cooling

This unit slots directly into compact CPU coolers or tight case vents where larger fans cannot reach. The three-pin plug connects to standard headers without adapters. Ball bearings handle continuous operation in restricted airflow paths. It frees up space around dense component layouts while providing targeted airflow.
