Single 120 mm PWM fan for high static pressure

This single 120 mm case fan uses a 4 pin PWM connector to deliver 500 to 2000 rpm and 70.8 CFM airflow at 22.6 dB‑A. The second‑generation hydraulic bearing and liquid crystal polymer blades are engineered for radiator and chassis cooling where strong static pressure matters.

PWM range and low‑noise adapter limit maximum speed

Without the supplied low‑noise cable the fan runs 500 to 2000 rpm producing 70.8 CFM at 22.6 dB‑A. With the adapter fitted the range drops to 500 to 1500 rpm, reducing airflow to 49.13 CFM and noise to 18.3 dB‑A. Static pressure peaks at 3.19 mm H₂O only at full PWM speed.

Check motherboard header

Your board must provide a standard 4 pin PWM header to control the fan curve. The frame is 25 mm thick so verify that your case, radiator or heatsink allows that depth and that the 120 mm mounting holes line up. Anti‑vibration pads are included but require four clear screw positions.

Questions about this item

One fan or two — which pack should I pick?

This listing is the single-fan pack (CL-F139-PL12BL-A). A two-fan version exists under a different part number (CL-F159-PL12BL-A) if you need a pair.

What does 70.8 CFM actually deliver inside my case?

At full PWM speed the fan moves 70.8 CFM with 3.19 mm H₂O static pressure at 22.6 dB-A, giving strong airflow through radiators or restrictive meshes.

How does the 4-pin PWM connector limit control?

The 4-pin PWM header lets the motherboard vary speed from 500 to 2000 rpm; with low-noise cable fitted the range drops to 500–1500 rpm and 18.3 dB-A.
