Cooler Master Masterfan MF140 Halo2 (MFL-B4DN-16NP2-R2)

The Cooler Master Masterfan MF140 Halo2 (MFL-B4DN-16NP2-R2) is a 140 mm case fan designed to combine striking RGB lighting with solid performance. The model works well for general airflow or mounting on radiators with moderate air resistance. The fan operates via 4-pin PWM, supports a rotation range from 0 to 1600 RPM, and delivers airflow of up to 59.5 CFM with static pressure up to 2.53 mm H2O. Maximum noise level reaches 27 dB(A). The lighting uses a 3-pin 5V ARGB Gen 2 connector, allowing the fan to sync with compatible motherboards and RGB controllers. Key design features include blades that are 10% larger, a hybrid frame construction, and an updated IC driver—all engineered to balance performance with acoustic output. Dimensions are 140 × 140 × 25 mm and weight is approximately 210 g. The black finish makes this fan a versatile choice for dark PC builds with transparent side panels.
