etaPERF™ motor
Noctua’s new etaPERF™ motor sets new standards in energy efficiency thanks to its extremely low electric impedance and the latest NE-FD6 drive system with its integrated, ultra-sensitive Hall effect sensor that provides super-precise commutation performance. This not only enables it to convert a minimal electric input into a maximum power-output with hardly any losses, but also works in tandem with Noctua’s proven Smooth Commutation Drive 2 technology to make the etaPERF™ motor run near-inaudible.
SupraTorque™
Most fans become slightly slower when working against back pressure such as on heatsinks and radiators, which results in reduced performance. Enabled by the new NE-FD6 driver IC, Noctua’s SupraTorque™ technology allows the fan to leverage additional torque headroom when required in order to keep its RPM speed at the desired level no matter the airflow resistance, ensuring consistent performance even in the most demanding conditions.
