With lower ripple at +12V (<20mV), the Phanteks unit could reach the performance of the ROG Strix model, which uses the same platform.

Unfortunately, the fan speed profile is aggressive, so the overall noise output exceeds 30 dB(A). The difference with the Phanteks unit and the Corsair and the Asus ROG models is vast.
