AMD is quite obviously benefiting from the
Shitstorm around the voltage transformer cooling on the X299 motherboards with Intel's socket 2066. Asrock, Asus, Gigabyte and MSI showed their first TR4-boards with X399 chip AMD's webinar "Meet the Experts" In cooling partly differ significantly from the shown patterns on the Computex in late May, early June.
Gigabyte has split the voltage converter range over the Ryen threadripper CPU and to the left of the RAM banks. Both parts now have larger heat sinks with apparently more slats (difficult to see from above). At least on the rendered pictures the heat sink above even briefly covers the bolt hole for fastening in the housing. A heatpipe for the even distribution of waste heat completes the reworked design. This is also the case with the Asrock models X399 Fat1lity Professional Gaming and X399 Taichi. In order to prepare the space for the heat pipe, the layout was somewhat adapted by exchanging the eight- and four-pole EPS power connector.
For the first time, MSI has now shown the X399 Gaming Pro Carbon, which is the only mainboard to realize all voltage converters and their complete cooling over the TR4 socket. The heat sink is already a small tower, which comes with plenty of slats. It could only be a problem with the CPU cooler, whose space is limited.
