Test Setup
For our tests, we used a test rig which includes the ASRock X299 Taichi motherboard, along with an Intel Core i5-7640X (Kaby Lake-X) at default clock speed of 4.0GHz (turbo boost 4.2GHz), as well as 8GB of G.Skill Trident-Z DDR4-3200 ram in dual channel mode.
All tests were conducted at turbo clock speeds of 4.2GHz at a resolution of 1920×1080. High or Ultra settings enabled.

Note: We’ve tested the board with several DDR4 memory modules and we failed to enabled XMP profiles. It could be a BIOS issue or may be my ram isn’t compatible with the board. In the end, we conducted the tests at default DDR4-2133. During overclocking we upped it to DDR4-2400.

Idle Temps
Idle temps look good at around 38 degrees Celsius. Nothing out of the ordinary.
Load Temps
Load temps however, was surprisingly high at 67 degrees Celsius. This is in fact, quite normal for a KabyLake-X with a TDP of 112W. Expect even higher temperatures for the SkyLake-X which has a TDP of 140W.
With such high temperatures, we recommend that you invest in a very good CPU cooler. Getting an all-in-one liquid cooler (AIO) is highly recommended. I think air coolers are not up to the job.
