Japanese PC cooling expert Scythe unveiled its brand new high-performance PC fan series, the Grand Flex. The company started off with its 28 mm-thick 120 mm variants, among which are four fixed-speed variants, including the Grand Flex 800 RPM (SM1225GF12SL), 1,200 RPM (SM1225GF12L), 1,600 RPM (SM1225GF12M), and 2,000 RPM (SM1225GF12H). All four of these feature 3-pin connectors. Scythe also unveiled the Grand Flex PWM (SM1225GF12SH-P), which spins at 600 to 2,500 RPM, and features 4-pin PWM fan control.
The Grand Flex series feature a unique new impeller design that maximizes air-flow at the given speeds, resulting in good airflow-to-noise ratios. The 800 RPM variant pushes 30.5 CFM at 18 dBA noise output; the 1,200 RPM variant does 45.8 CFM at 23.5 dBA; the 1,600 RPM does 61.1 CFM at 28.5 dBA; and the 2,000 RPM variant pushes 76.6 CFM at 34.5 dBA. The Grand Flex PWM pushes 24.2 to 98.6 CFM, with a noise output ranging between 13.5 to 39.5 dBA. Its head features fluid-dynamic bearing, with a lubricant that can withstand temperatures as high as 250°C. Scythe didn't release pricing, but announced it would begin shipping these fans by July 3.
