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.

Questions about this item

Does my motherboard need a 4-pin PWM header and a 5V 3-pin ARGB header for each fan?

Each fan uses a single 4-pin PWM connector for speed control and a 5V 3-pin ARGB connector for lighting, so your board needs one of each per fan or a splitter hub.

Will the 115 CFM airflow and 6.82 mm H₂O pressure overwhelm a standard 120 mm radiator or filter?

The 38 mm thick frame delivers 115 CFM and 6.82 mm H₂O, which is higher than typical 25 mm fans, so it pushes through dense radiators and filters more effectively.

How can I confirm the fans are running at the 800–2500 RPM range and the ARGB is synced?

Check fan speed in BIOS or monitoring software to see it vary between 800 and 2500 RPM, and verify ARGB sync by selecting a motherboard lighting effect that changes all three fans together.
