This atleast solves the problem for us, since it now no longer advertises a fake temperature. The board P4SCE/P4SCA bios version 1.2c (or higher) will soon be released officially with this bugfix. Hopefully they will include support for actual temperature readout at some time. Supermicro staff: Thank you =) Sincerly Hans K. Rosbach
