Ocypus Sigma F12 ARGB 120mm PWM Case Fan, Black, Hydraulic Bearing, 65 CFM, Addressable RGB

Push up to 65 CFM of airflow with the Ocypus Sigma F12 ARGB, a 120mm PWM case fan that pairs hydraulic bearing durability with vibrant addressable RGB lighting. The 4-pin PWM connector allows precise speed control from 800 to 1800 RPM, while the 3-pin ARGB header syncs lighting effects with your motherboard. With a maximum noise level of 30 dBA and a static pressure of 1.8 mmH2O, it is suitable for both unrestricted airflow and radiator or heatsink use. The black frame and translucent fan blades create a clean look that lets the lighting shine through.

Overview

The Sigma F12 ARGB is built around a hydraulic bearing rated for 40,000 hours, providing long-term reliability. Its 120mm size fits standard case fan mounts, and the PWM control ensures the fan speed adjusts dynamically based on system temperatures. The ARGB lighting uses a 5V 3-pin connection, compatible with most modern motherboards and controllers. Rated at 12V DC for the fan and 5V DC for the LEDs, the fan draws 0.15A and the LEDs 0.35A.
