Focused Flow frame for pressure demanding applications such as heatsinks and radiators. Advanced aerodynamic design measures improve efficiency and make the fan's sound pattern more agreeable to the human ear. Integrated Anti-Vibration Pads minimise the transmission of minute vibrations. SSO2 Bearing and a metal bearing shell guarantee superior long-term stability. Low-Noise Adaptor reduces the maximum fan speed from 1500 to 1200rpm.
