Now I remembered... Dell has released info about their smbios extensions with example programs at: https://linux.dell.com/libsmbios/main/ https://linux.dell.com/cgi-bin/gitweb/gitweb.cgi?p=libsmbios.git;a=summary But there is nothing about fan control or temperature. Also I found smbios specification: http://www.dmtf.org/standards/smbios There is something written about fan and temp, but no idea if it is usefull for something... -- Pali Rohár pali.ro...@gmail.com
