Hi, Are there any i2c buses available on your card? e.g. # ls /sys/devices/pci*/*/*02:00.0 On an 8800GT I can access thermal sensors and fan speed settings via: # modprobe adt7473 # modprobe adt7475 # ls /sys/devices/pci0000:00/0000:00:0f.0/0000:18:00.0/i2c-4/4-002e Regards, -- Steven Chamberlain steven@pyro.eu.org
