The Grand Flex PWM is the latest, new creation in the Scythe line-up. Forget old, although proven engineering - every major component was re-developed at its' core. The Grand Flex is equipped with a closed-up liquid bearing (Sealed Precision FDB) where the rotor shaft rotates on an oil-film created by dynamic pressure. This technique greatly reduces running noise and friction, which again slows down wear and tear of the bearing. The newly designed fan blades focus the airstream to the desired cooling area to optimize cooling efficiency.
