12025 Sanyo case fan for 12 V systems

This 12 cm cooling fan carries the original Sanyo 9G1212A403 designation and runs on a 12 V supply drawing 0.40 A. It is intended for desktop or server chassis that accept a standard three-wire connection. The unit is supplied new and ready for installation.

Three-wire interface limits speed control

The fan uses a three-wire header providing power, ground and tachometer signal but no PWM line. Builders who need motherboard-controlled variable speed should choose a four-wire PWM model instead.

Questions about this item

What does the 0.40 A current draw mean for my fan header?

The fan draws 0.40 A at 12 V, which is within the typical 1 A limit of most motherboard fan headers, so it can run directly from a single header without a splitter or external power.

How does the three-wire interface affect speed control?

The three-wire connector provides power, ground and a tachometer signal for RPM monitoring, but lacks a PWM wire, so speed can only be adjusted by varying the voltage supplied to the header.
