Power Consumption and Temperatures

The ASRock X299 Gaming i9 did amazingly well in power-consumption testing at load, both at stock and overclocked, although reasonable results in regards to overclocked power consumption numbers are with a manual setting of 1.8V for the CPU input voltage, as the automatic 2.1V was too high and resulted in CPU throttle. The PCH cooler seems a bit underwhelming in performance, while the VRM heatsink does reasonably well with very minimal airflow. So far, these ASRock X299 boards I have tested seem to have great digital VRM designs that really pay off when it comes time to push the CPU clocks up.
