OEM Industries 2004KL-04W-B59 50mm 12V 3-Wire CPU Cooler

Compact 50 mm 12 V fan for tight builds

The OEM Industries 2004KL-04W-B59 is a 50 mm square DC cooler that draws 0.14 A at 12 V. It suits small-form-factor PCs, embedded boards or replacement jobs where a low-profile airflow source is required. The three-wire connector reports speed to the motherboard for basic monitoring.

Three-wire power and ball-bearing reliability

A standard three-wire header supplies power and tachometer feedback without PWM control. The ball bearing reduces wear compared with sleeve designs, helping the fan maintain consistent rotation in continuously running systems. No LED lighting keeps the unit visually neutral inside any chassis.

Steady airflow under constant load

Ball-bearing construction and a fixed 12 V supply let the cooler sustain its rated speed during extended operation. Without PWM the fan runs at full voltage continuously, so thermal performance remains predictable during long compute sessions. Builders needing variable speed or higher static pressure should consider a four-wire alternative.
