Grand Flex

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.

Features

Sealed Precision FDB
This newly developed bearing is a closed-up (sealed) system, in which the rotor shaft smoothly runs on an oil film. Compared to conventional sleeve bearings, sealed precision FDB works more quietly and results in slower wear and tear of the bearing.The applied lubricant oil can take temperatures of up to 250°C.

 


Fan Blade Design
The new fan blade design reduces turbulence and guides the airflow to the desired area. This effect is further enchanced by the angled shape of the blades towards the hub.

 

 

Vibration-Free Mounting
Enclosed with the Grand Flex are optional insulation rubbers to prevent the passing on of possible vibrations to the PC case, contributing to a more quiet operation.

 

4-Pin Molex Adaptor
The 500 mm length, 3-pin cable enables direct hooking up to the mainboard, or alternatively, a fan controller unit. If direct connection to the power supply unit is preferred, the included 3-pin to 4-pin molex adaptor is at hand.
