Kaze Flex 120 ARGB PWM

ARGB version based on the award-winning Kaze Flex PWM fans. The translucent fan blades are illuminated by individually controllable, addressable RGB LEDs, which offer a breathtaking visual accent with continuously changing light effects and colors. The effects can be controlled directly via standard 3-pin 5V controls from various manufacturers. Thanks to the unique Sealed Precision FDB bearing, the fans run particularly smoothly and have a long service life of over 120 000 hours. Rubber decouplers installed in the fan frame minimize the transmission of vibrations and thus ensure a pleasantly low operating noise. The fan frame and decoupler are completely black. The Kaze Flex 120 ARGB PWM fans are suitable for use both as case fans and for active cooling of CPU coolers or radiators. Two different models with a fan speed of 1200 or 1800 rpm cover a wide range of applications.


Adressable RGB Design

Ten individually controllable LEDs illuminate the translucent fan blades and enable complex color effects and gradients.

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 250°C / 480°F. This drastically reduces friction, ensuring smooth operation and minimized wear, which results in an average life-span of 120 000 hours.

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.
