Again – the HE01 was tested in both Q and P modes throughout the overclocked testing too. During Q mode, the fan ran at 1200RPM whilst in P mode 2000RPM. Performance from this fan is exceptional, it manages to single-handedly repel unwanted heat – projected it above other popular rivals. Noise was an issue however, especially so at 2000RPM (100%). For testing purposes this is bearable but for general usage, some may want to fix fan speed to a lower setting.
