Scythe Grand Flex SM1225GF12L

The Grand Flex PWM is the latest development from Scythe. Instead of relying on traditional techniques, the core components have been completely re-engineered from the ground up. The bearing is based on a sealed liquid bearing (Sealed Precision FDB). The rotor shaft rotates on an oil film generated by dynamic pressure, which reduces operational noise, friction, and wear on the bearing. The newly designed shape of the fan blades focuses the airflow towards the areas that need cooling, enhancing cooling performance.

This newly developed bearing is a closed system. The rotor shaft itself runs on an oil film. As a result, this fan bearing operates more quietly and with less wear compared to conventional sliding bearings. The special oil used for lubrication, which is temperature resistant up to 250 °C, supports these positive characteristics.

The unique design of the fan blades minimizes turbulence and directs the generated airflow directly to the areas that need cooling. This effect is further enhanced by the angled shape of the fan blades in the inner area.

The Grand Flex comes with vibration dampers for the installation of the fan. These effectively prevent the transmission of any vibrations that may occur to the PC case, actively increasing the smooth operation of the fan.

The fan can be connected directly to the motherboard or a fan controller via the 500 mm long 3-pin connection cable. If this is not possible or desired, a 3-pin to 4-pin Molex adapter is included for direct connection to the power supply.
