Ask FASE NUEVE ↗Nine blades that really push.
The Progressive-Bend impeller is made of Sterrox LCP and its nine blades sweep backwards near the hub and forward at the tip. It moves 155.6 m3/h - 91.58 CFM - with 2.56 mm H2O of static pressure, which is what it takes to push through a radiator or a dust filter.
From 0 to 1,500 rpm, and it stops completely.
The range starts at zero: with a PWM curve that allows it, the fan stops when the machine is idle. At full speed it stays at or below 24.8 dB(A). The SSO2 bearing is rated above 150,000 hours.
140 mm, 4 pins and everything in the box.
Standard 140 x 140 x 25 mm format and a 4-pin PWM connector at 12 V. The box carries the mounting accessories and cables Noctua includes, and the chromax.black finish is black throughout.
