140 mm PWM case fan with addressable RGB

The Geometric Future Squama 2503 is a 140 mm fan built for builders who want a single unit that fits standard mounting points and adds addressable lighting. It connects via a 4-pin PWM header and a 5 V 3-pin ARGB header for motherboard synchronisation. The white finish suits light-themed builds.

Hydro Dynamic Bearing thermals

Hydro Dynamic Bearings support a speed range of 800 to 2400 rpm, delivering 91.15 CFM airflow and 2.63 mm H₂O static pressure. At maximum speed the fan reaches 34 dB(A). Anti-vibration rubber pads reduce transmitted vibration to the chassis.

Squama frame particles sustain airflow under load

The patented Squama particles on the frame reduce turbulent flow noise while maintaining airflow and pressure efficiency during prolonged operation. PWM control adjusts speed dynamically so the fan balances cooling performance and acoustic output over extended workloads.

Questions about this item

How do I install the 140mm fan with the 4-pin PWM connector and the 5V 3-pin ARGB header, and what step do people often miss?

Mount the fan using the four screw holes, connect the 4-pin PWM cable to the motherboard fan header and the 5V 3-pin ARGB cable to a 5V 3-pin addressable RGB header; the step often missed is plugging in the ARGB cable so the dual light loop can synchronise with motherboard software.

What maintenance or replacement will the hydro dynamic bearing fan need later?

The hydro dynamic bearing is sealed and requires no lubrication; over time dust can accumulate on the blades and the squama particle frame, so periodic cleaning with compressed air keeps airflow at 91.15 CFM and noise at 34 dB(A).

What limit appears first when the fan runs at 2400 RPM for long periods?

At the maximum 2400 RPM the noise level reaches 34 dB(A), which is the first noticeable limit under sustained use; the 4-pin PWM curve will reduce speed when thermal headroom allows.
