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=3Dlibsmbios.git;a=3Dsumm= ary 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... =2D-=20 Pali Roh=C3=A1r pali.rohar@gmail.com --nextPart1596174.2dAsavLYgY Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iEYEABECAAYFAlN36jUACgkQi/DJPQPkQ1KBmQCfZoVo35XrffiKZutQMsJJpVbE 8CMAn1/z0sy/64jMPqbieCv6KiJ7fM3N =7hnU -----END PGP SIGNATURE----- --nextPart1596174.2dAsavLYgY--
