Hmm, too bad the BIOS doesn't allow undervolting, that'd lower temps significantly. For Linux, one thing that you can do to lower temps for day-to-day use is to switch from the default ondemand/schedutil governor to powersave. Phoronix did some testing early on that showed a not-too-bad performance hit for a bunch of use-cases with a significant power savings. When I run my system w/ powersave, it pretty much parks the cores at 1.55GHz w/ no noticeable perf hit when I'm just browsing/typing/etc. Switching governors back to performance or schedutil is a simple cpupower command in the terminal. Not as nice as having Ryzen Master/software OC options, but fingers crossed that'll come in a future kernel update. (Honestly, I'd just like if AMD would publish the BIOS and Kernel Developer's Guide for Ryzen so that CPU lm_sensors support can be added.)


BTW, for motherboard sensors, the MSI boards use a Nuvoton chip and can be supported w/ the nct6775 module. Gigabyte boards seem to use it87 modules.
