OEM Industries 4715FS-12T-B50 120mm CPU cooler

Industrial 120 mm AC Fan

The OEM Industries 4715FS-12T-B50 is a 120 mm square AC fan designed for equipment cooling rather than desktop CPU sockets. It runs directly from 115 V mains at 50 or 60 Hz single-phase, drawing 0.21 A at 50 Hz and 0.19 A at 60 Hz. The two-pin connector supplies line power without PWM or tachometer signals. This unit suits industrial enclosures, server racks or custom ducting where AC power is already present.

Airflow and Acoustic Limits

At 3000 to 3499 rpm the fan moves more than 80 cfm, giving strong forced convection through dense heatsinks or restricted vents. Noise sits between 40 and 45 dBA at that speed, which is audible in quiet rooms but typical for industrial airflow. Ball bearings support continuous duty, yet the fixed AC frequency means no speed control or low-noise idle mode. Builders needing variable flow or near-silent operation should look elsewhere.

Integration Requirements

Mounting uses the standard 120 mm square pattern, but the 115 V AC input demands safe wiring practices — fusing, strain relief and isolation from low-voltage circuitry. No DC supply, motherboard header or fan controller can drive this model directly. The absence of LEDs keeps the profile clean for rack fronts or ducted exhausts. Ensure the enclosure provides a grounded AC feed and enough clearance for the 38 mm thick frame.
