Geometric Future Squama 3805 ARGB PWM 120×38mm 3-pack

120 mm triple-fan kit

The Geometric Future Squama 3805 kit contains three 120 mm case fans with a 38 mm frame depth. Each unit uses a ball bearing and 4-pin PWM control to spin between 800 rpm and 2500 rpm. Addressable RGB lighting on a 5 V 3-pin header lets the system synchronise colours, and a supplied controller adds seven preset modes plus eight static colours for boards without an ARGB header.

Builders who want high static pressure

The 6.82 mm H₂O pressure rating suits dense radiator stacks or restrictive front panels where airflow must push through tight fins. Anti-vibration rubber pads reduce transmitted noise at higher speeds. Users who prefer slimmer 25 mm fans for standard chassis clearance or who need a single fan rather than a three-pack should consider other options.

Sustained-load behaviour

The revised curve blade design and patented Squama particles on the frame smooth turbulent flow, keeping the 115 CFM airflow figure stable during prolonged operation. Dynamic balancing minimises vibration as the motor settles into its running range. The combination maintains consistent cooling throughput without the drop-off seen in short-burst tests.
