Japanese CPU cooler and case fan expert Scythe proudly presents its new
top-notch Grand Flex 120 mm fan series. These new axial fans surprise with the
aggressive design and are set to be the successor of the incredibly successful
S-FLEX series, taking it to the next level in terms of design and
"Sealed Precision FDB" was newly developed from scratch as the core for its
Grand Flex 120 mm series. This bearing is based on the "Fluid Dynamic Bearing"
technology that has served Scythe well for several popular high-end series in
the past and is now being used as a very solid and reliable foundation for the
new design. Scythe’s Fluid Dynamic Bearing utilizes lubricantoil between the
shaft and the bearing, resulting in excellent lubrication and silent operation.
The used high-grade lubricant oil can withstand high temperatures of up to 250
degree Celsius, and are additionally of special interest for industrial use.
Grand Flex 120 case fans are made for long time silent operation and are rated
with MTTF (Mean Time To Failure) of 120.000 hours (at 25 degree Celsius).
Another highlight is the completely new design of the 9 blades of the Grand
Flex 120 and Grand Flex 120 PWM models. Each fan blade is made especially robust
and is equipped with an indentation close to the center-hub. Hence allows much
more focused and more concentrated airflow towards the cooling area, resulting
in better performance when used with cooler heatsinks. In order to reduce the
vibration transferred to PC chassis, a set of vibration dampers is supplied with
each Grand Flex 120 case fan. In addition, all Grand Flex 120 case fans come
with a 500 mm long cable, which is sleeved – allowing it to be conveniently used
even in big tower chassis.
To match every users taste, Scythe Grand Flex 120 axial fans are available in
five different variations. For users seeking constant airflow at fixed speed,
total of four models are available, including 800 rpm, 1.200 rpm, 1.600 rpm and
2.000 rpm. Users seeking a fan with PWM support, can rely on the Grand Flex 120
PWM model, which offers a very wide fan speed range from 600 up to 2.400
