Compact 50mm case fan

The OEM Industries CF-12520B is a 50 by 50 by 20 millimetre axial fan designed for tight chassis spaces. It runs on twelve volts DC at zero point three seven amps and uses a three pin power connector. The black frame houses a ball bearing for durable rotation without LED lighting.

Three pin 12V power interface

This fan draws power through a standard three wire three pin header supplying twelve volts at zero point three seven amps. The connector matches common motherboard or fan controller headers. No PWM wire is present so speed control depends on voltage regulation by the header.

Suits small form factor builds needing a 50mm

Builders repairing or upgrading compact cases, industrial enclosures or legacy coolers that accept a fifty millimetre frame will find a direct fit. Buyers who need PWM speed signalling larger airflow or RGB illumination should look at other models.

Questions about this item

What does 0.37 A at 12 V mean for airflow in my case?

The motor draws 0.37 A from a 12 V rail, so the fan moves air through its 50 × 50 × 20 mm frame using a ball-bearing spindle.

What does the 3-pin connector limit for speed control?

The 3-pin header supplies constant 12 V power and a tachometer signal; voltage regulation from the motherboard is the only way to change speed.

Will the 50 × 50 × 20 mm frame fit my chassis fan slot?

The fan measures 50 mm square by 20 mm thick with standard mounting holes, so it fits any 50 mm case opening.
