Compact 50 mm CPU fan

The OEM Industries U50R05NS9Z7-53 is a 5015 frame DC square cooler built for tight spaces. It suits builders who need a low-profile fan to move air through small-form-factor cases or rackmount chassis.

Fits 3-pin headers and frees larger slots

The 3-pin power connector plugs directly into standard motherboard or controller headers. Its 50 by 15 mm footprint leaves surrounding expansion slots and memory modules unobstructed.

Ball bearing and no LED

The ball bearing assembly reduces friction for consistent rotation at 4.8 V and 0.11 A. Absence of lighting keeps the unit suitable for environments where illumination is unwanted.

Questions about this item

Will the 50 mm frame fit the mounting holes on my motherboard?

The fan measures 50 mm square and 15 mm thick, matching the standard 5015 footprint used on many small-form-factor boards.

How loud is the ball-bearing fan when it runs continuously at 4.8 V?

Ball bearings typically produce a steady, low-pitched hum that remains constant over long periods; no LED or PWM circuitry adds extra noise.

Does my motherboard need a 3-pin header to power this cooler?

Yes, the cooler draws 0.11 A at 4.8 V through a standard 3-pin connector, so an available 3-pin fan header is required.
