Geometric Future Squama 2503R 140mm case fan 3-pack

Three-pack reversed-blade 140mm fans

The set contains three 140mm case fans with a 25mm frame and reversed blades that can serve as intake fans while showing the front face. Hydro Dynamic Bearings and a patented Squama particle texture on the frame reduce turbulent noise while improving airflow and pressure efficiency. PWM control adjusts speed between 800 and 2400 RPM. Dual addressable RGB light loops on each fan connect to a standard 5 V 3-pin header for motherboard synchronisation.

Builders who want coordinated lighting

Suitable for systems that need matched intake or exhaust fans with addressable RGB effects and a wide speed range for quiet or high-performance curves. The reversed blade design is a specific aesthetic and functional choice; builders who prefer conventional blade orientation or single-loop lighting should look at other models. The three-fan pack also assumes enough 140mm mounting points for all units.

91.15 CFM airflow at 2.63 mm H2O static pressure

Peak airflow reaches 91.15 CFM with 2.63 mm H2O of static pressure at the maximum 2400 RPM setting, while noise stays at 34 dB(A). This single figure set determines whether the fans can move enough air through restrictive radiators or dense mesh panels for a given thermal target.
