Zyvpee EFB0412MD 40mm 12V 0.15A 4020 Ball Bearing Case Fan

40 mm ball-bearing case fan

The Zyvpee EFB0412MD is a 40 mm square case fan with a 20 mm thickness designed for tight chassis locations. It uses a ball bearing for durable rotation and a three-pin power connector for direct motherboard or controller attachment. The non-LED black frame suits builds that prefer no lighting.

12 V 0.15 A power specification

This fan operates at 12 volts and draws 0.15 amperes, making the electrical profile the single figure that decides compatibility with a given header or device. Matching both voltage and current to the target equipment ensures correct start-up and steady speed.

Fits 4020 mount patterns in network gear

The 40 by 20 mm footprint matches the 4020 mounting pattern used in Huawei H3C 3600 and 5600 series switches. It provides adequate airflow for those specific appliances but lacks the dimensions or connector options for larger server or desktop chassis.
