Compact 45 mm server cooling fan

The TOPLAB ADDA AP4512MX-G90 is a 45 mm square DC fan built for server and networking chassis. It runs on 12 V and draws 0.06 A through a two-wire connection. The low-profile 8 mm frame fits tight 1U or blade slots where taller fans cannot sit.

Two-wire 12 V power only

This unit has no PWM or tachometer lead, so speed control and monitoring depend on the host board supporting voltage regulation. Buyers who need four-wire PWM control or a feedback signal should choose a different model.

Questions about this item

What does the 12 V rating mean once the fan is installed in a server?

The fan runs on a 12 V DC supply, drawing 0.06 A, so it delivers its rated airflow at that voltage without needing a separate regulator.

What does the 2-wire interface cap in practice?

The two wires provide power and ground only, so speed is fixed at the rated RPM and cannot be adjusted or monitored by the motherboard.
