40mm 12V SANYO 4056 Fan

The OEM Industries 9CRD0412P5K03 is a 40mm square fan built around the SANYO 4056 platform. It draws 1.2A at 12V and connects through an 8-wire interface. The black housing uses a ball bearing for rotation. This unit suits technicians replacing a failed cooler fan or integrating targeted airflow into tight industrial enclosures.

Sustained 8-Wire Operation

The 8-wire connection enables continuous speed reporting and PWM control without signal loss during long runs. Ball bearing construction maintains consistent torque and acoustic profile when the fan operates at fixed or variable duty cycles for extended periods. The 12V 1.2A rating delivers stable current draw under load, preventing voltage sag that can stall smaller 2-wire alternatives.

Direct SANYO 4056 Replacement

This model matches the original SANYO 4056 form factor and 8-wire pin-out, so it drops into existing mounts without bracket changes. The upgrade is worth it when the original sleeve-bearing unit develops rattle or fails to report RPM to the controller. Builders needing a 3-wire or 4-wire connector, or a larger frame size, should look elsewhere.

Questions about this item

How much heat and noise does the 9CRD0412P5K03 generate when running continuously at 12V 1.2A?

The 40mm ball-bearing fan draws 1.2A at 12V, so sustained operation produces a steady airflow with typical ball-bearing acoustics; actual noise and surface temperature depend on the heatsink it is mounted to and the case airflow around it.

What connector or header must my motherboard provide for the 8-wire lead on this 4056 fan?

The 8-wire cable requires a matching 8-pin PWM or control header; verify your board has that exact pinout before installation.

Will the 40mm 9CRD0412P5K03 clear the taller VRM heatsinks on my older socket 412 board?

At 40mm square the fan sits low, but clearance depends on the specific cooler base and motherboard layout; measure the gap between the CPU socket and the nearest VRM heatsink before fitting.
