The OptimX A240B 2-fan case fan set, 240x120, provides PWM-controlled cooling and ARGB lighting for your PC build. The rotation speed can be adjusted between 1000–2200 RPM ±10%, and airflow reaches up to 47.5 CFM. The black finish and customizable lighting complement the look of the case.

The OptimX A240B set combines PWM cooling with ARGB lighting

PWM control adjusts the rotation speed to the system’s needs, while ARGB lighting adds a visual element to the build. The hydraulic bearing supports smooth operation, and the noise level is 18.3–28.8 dBA.

• Set of 2 fans, model A240B
• Dimensions: 243.8 × 120 × 25 mm
• Rotation speed: 1000–2200 RPM ±10%
• Airflow: up to 47.5 CFM; static pressure: up to 1.95 mmH₂O
• Separate connectors: 4-pin PWM and 3-pin ARGB
• Rated voltage: 12 V; rated current: 0.15 A ±0.04 A (max.); power consumption: 3.2 W

The connectors separate rotation adjustment from case lighting

Connect power and speed control through the 4-pin PWM connector, and lighting through the 3-pin ARGB connector. This separation lets you manage the cooling function and lighting effect through their respective connections.

The 243.8 × 120 × 25 mm format fits compatible builds

Each fan measures 243.8 × 120 × 25 mm, and the set is intended for use in PC cases compatible with this format. Before installation, check that the available space and system connections match the fans’ dimensions and connectors.

Rated service life is 4,000 hours

The Hydraulic Bearing and 4,000-hour service life are relevant features when choosing a set for case cooling. The fans operate at 12 V, with a rated current of 0.15 A ±0.04 A (max.), offering PWM control and ARGB lighting in a black design.
