Compact 45 mm fan-only cooler

The OEM Industries YW04510012BH is a 45 mm square, 10 mm thick fan unit designed for tight clearance spots such as small-form-factor cases, rackmount servers or embedded boards. It draws 0.14 A at 12 V through a standard three-pin connector and uses a ball bearing for longer life than sleeve alternatives.

Capacity and headroom

At 4.5 cm side length the fan moves enough air for low-power CPUs, chipset heatsinks or VRM zones, but it cannot sustain heavy desktop processors under prolonged load. The three-pin header provides voltage control only, so speed ramps linearly with voltage rather than offering PWM precision.

Thermals noise and power

Ball-bearing construction keeps acoustic output steady over time, while the 12 V 0.14 A draw adds minimal load to a system fan header. In typical chassis airflow the unit runs quietly at idle and remains audible but not intrusive when spun up for sustained component cooling.

Questions about this item

Will this 45mm fan fit alongside my existing 3-pin headers on an older motherboard?

Yes, it uses a standard 3-pin connector running at 12V and 0.14A, so it plugs directly into any legacy 3-pin header without adapters.

How can I confirm the ball-bearing fan is spinning correctly after installation?

Connect the 3-pin header, power on the system, and verify the fan rotates smoothly at 12V; the ball bearing should run quietly with no grinding or wobble.

Does the box include mounting screws or a heatsink, or is it only the 45x45x10mm fan unit?

The package contains only the 45mm Y.S.TECH 4510 fan itself; mounting screws, a heatsink base or any additional brackets must be sourced separately.
