rotational speed) meet the ETSI standard and the fans meet heat
dissipation requirements of a fully configured system.
Linear variation The fan speed is adjusted smoothly in linear mode,
without a sharp increase in noises.
High speed (100% Fans rotate at high speed to meet heat dissipation
rotational speed) requirements.
