40 mm SANYO 12 V fan

The OEM Industries 109P0412G3D073 is a 40 mm square cooling fan built by SANYO for 12 V operation. It draws 0.31 A through a standard three-pin connector and carries no LED lighting. The unit is sold as a fan only, without heatsink or mounting hardware. It suits technicians replacing a failed 4028-size fan in compact chassis or legacy CPU coolers.

Three-pin power connector

The three-wire interface supplies power, ground and a tachometer signal so the motherboard can monitor rotational speed. No PWM wire is present, so voltage control is the only speed-regulation method available. Because the package contains only the fan itself, installers must reuse existing screws, brackets or retention clips from the original cooler assembly.

Repairers needing a 4028 replacement

This fan fits builds that specifically require a 40 mm by 28 mm frame with 12 V 0.31 A ratings and a three-pin header. It does not suit systems that demand PWM control, larger frame dimensions, higher airflow specifications or integrated RGB illumination. Buyers needing a complete cooler kit with heatsink and mounting parts should look elsewhere.

이 상품에 대한 질문

Will the 109P0412G3D073 sleeve bearing need relubrication or replacement?

The 40 mm sleeve-bearing fan is not user-serviceable; when noise or speed drops, replace the whole 109P0412G3D073 unit.

What limits continuous operation of the 12 V 0.31 A motor?

The 12 V 0.31 A rating is the thermal ceiling; sustained load at that current will hit the motor’s temperature limit first.

How loud and warm does the 4028 fan get running all day?

The 4028 12 V 0.31 A fan runs at a modest current, producing a low hum and slight warmth that case airflow disperses.
