With the F series, Arctic offers a 120 mm fan with a classic frame design, which is used universally in housings and on coolers. The peculiarity, however, shows in the design of the fan blades. While conventional models rely on seven blades, nine fan blades are installed here . This allows a higher delivery volume at a constant speed and thus a similar volume.As a result, the 120 mm fan shovels up to 90.1 m / h (53.03 cfm) at a maximum of 1,350 rpm . It generates a volume of a maximum of 0.4 sone. The FDB bearing (Fluid Dynamic Bearing) is a hydrodynamic plain bearingand is equipped with an oil capsule. This prevents the loss of the lubricant, making the bearing as quiet as a plain bearing with a significantly longer service life.Technical details:- Dimensions: 120 x 120 x 25 mm- Weight: 105 g- Material: Plastic- Colour: Black- Volume: max. 0.3 sone / 22.5 dba- Speed: 250 - 1,350 rpm- Airflow: max. 90.1 m / h (53.03 cfm)- Static pressure: 1.00 mmH2O- Voltage: 12V- Starting voltage: 6 V- Amperage: 0.24 A.- Connection: 4-Pin (PWM + Power)- Cable length: 400 mm
