14mm low ,Measuring only 14mm in thickness, the -A9x14 is much slimmer than standard 92x25mm fans. This makes it ideal for all applications where standard fans would take up too much space, such as low profile CPU coolers in HTPC builds or server environments Flow Acceleration Channels,The -A9x14 impeller features suction side Flow Acceleration Channels. By speeding up the airflow at the crucial outer blade regions, this measure reduces suction side flow separation and thus leads to better efficiency and lower noise Stepped Inlet Design 's Stepped Inlet Design adds turbulence to the influx in order to facilitate the transition from laminar flow to turbulent flow, which reduces intake noise, improves flow attachment and increases suction capacity, especially in space-restricted environments Low-Noise Adaptor The -A9x14 is supplied with a (L.A.) that reduces the maximum fan speed from 2200 to 1700rpm. The L.A. can be used either to run the fan at a fixed speed of 1200rpm or to cap the maximum speed when using automatic PWM control Featuring frame and sophisticated aerodynamic design measures such as Flow Acceleration Channels, the -A9x14 is a highly optimised, premium quality quiet fan in 92x14mm size. Due to its thickness of only 14mm, the -A9x14 is a perfect match for low profile CPU coolers and all other applications that require slimmer fans. PWM IC for fully automatic speed control and reference class SSO2 bearings superb running smoothness and excellent long-term stability (The product printed words depending on the batch, but this does not affect use) Color: As Shown Material: plastic Package Contents: 1 * PWM PC Fan Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
