Hwinfo reading the ite sensor is what is causing the fan problems. Hwinfo author posted about this on his forum and said he's been in contact with Asus to get this fixed. ETA next bios update. Meanwhile you can disable ite monitoring from Hwinfo. Or just sell your board xD
Yes, I tried 4011 but not as stable or able to get RAM to full speed. As both have AGESA 22.214.171.124a code I suspect it's the vulnerability protection (SMU 43.18) that is problematic. 4008 now and it's fine.
