Compact 50 mm case fan

The OEM Industries BS501012H is a 50 mm square fan designed for tight spaces inside a PC chassis. It runs on 12 V and draws 0.16 A through a standard three-pin power connector. The ball bearing and black frame suit general case airflow or small CPU cooler replacements.

Replaces noisy or failed 50 mm fans

Swap this unit in when an existing 5010-size fan becomes loud, develops bearing rattle or stops spinning. The 12 V 0.16 A rating matches the original spec, so the jump is worth it when the old fan no longer moves enough air through a compact heatsink or chassis vent.

Simple three-pin installation

The three-wire connector plugs directly onto a motherboard or fan-controller header keyed for 501012 pinout. Alignment is the only common issue — forcing the plug offset by one pin bends the header and leaves the fan unpowered.

Questions about this item

Will the 50mm square frame with 10mm thickness fit my case fan slot?

The fan measures 50mm by 50mm and is 10mm thick, so it fits any standard 50mm mounting hole pattern.

How do I connect the 3‑pin connector so the motherboard reads speed correctly?

Align the three pins with the motherboard header — ground, 12V, and tach — and press straight in; forcing it sideways bends pins and loses RPM reporting.

When should I replace the ball‑bearing fan?

Replace it once the bearing noise becomes audible or the rotor stops spinning at 12V 0.16A, as ball bearings cannot be relubricated.
