Kaze Flex 120 Slim PWM

The Kaze Flex 120 Slim PWM have a height of only 17 mm and are particularly suitable for use on CPU Coolers that would no longer fit into the system due to the limited space, due to the form factor of the case or the expansive mainboard components. Despite the reduced dimensions, the technical advantages of the Kaze Flex series are retained. Thanks to the unique Sealed Precision Fluid Dynamic Bearing (FDB), the fans run particularly smoothly and have an average service life of over 100,000 hours. The decouplers installed in the fan frame minimize the transmission of vibrations and thus ensure a pleasantly low operating noise. The Kaze Flex 120 Slim PWM with 300 – 1800 rpm is also used on the compact Big Shuriken 3 CPU Cooler. Unregulated versions with a fixed rpm as well as a RGB-LED version are also available.


Sealed Precision FDB

In order to guarantee an exceptionally high level of stability and durability, the fans from the Kaze Flex Series are equipped with a self-contained fluid dynamic bearing (Sealed Precision FDB). The bearing and the spindle are made entirely of high quality compressed metal and lubricated by a special oil film resistant to temperatures of up to 250C° / 480F°. This drastically reduces friction, ensuring smooth operation and minimized wear, which results in an average life-span of 100 000 hours.

Reduced Height

Space-saving design with a frame height of just 17 mm. The height can be reduced further to 15 mm by removing the decouplers.

Integrated Anti-Vibration Sytem

The Kaze Flex fan series is equipped with vibration- and shock absorbing rubber pads which cover the tunnelless mounting holes. These decouplers effectively eliminate possible vibrations and allow low-noise operation.
