I've seen AUXTIN have values of -9.5, -9, -8.5 (changes with no restart 
needed).

Yesterday I watched the fan speed while compressing, and it switched 
from being auto-controlled (~4000-4300) to full-speed after temp1 shown 
68째C (then compression ended). The temperatures went down quickly, but 
the fan speed seemed to never go below 4800 after that (unless I missed 
another heat-up).

Since I turned C6 on in UEFI, Vcore in sensors is about 0.5-0.6 V when 
idle (that is mentioned in a Russian review with a screenshot: 
<http://www.overclockers.ua/motherboard/amd-apu-zacate/).

So, is it dangerous with the table maximum for the APU being 90째, and 
with the MSI E350IA-E45 auto mode starting the fan at 70 (same review, 
page 3)?
