Well, on my machine, fan is an empty directory.
The ls command gives:

msb01:/proc/acpi# ls -la
totale 0
dr-xr-xr-x  10 root root 0 2007-11-08 07:15 .
dr-xr-xr-x 181 root root 0 2007-11-08 08:14 ..
dr-xr-xr-x   3 root root 0 2007-11-08 09:15 ac_adapter
dr-xr-xr-x   3 root root 0 2007-11-08 07:16 battery
dr-xr-xr-x   4 root root 0 2007-11-08 09:15 button

-rw-r--r--   1 root root 0 2007-11-08 09:15 wakeup
msb01:/proc/acpi#          

And for fan:

msb01:/proc/acpi# cd fan
msb01:/proc/acpi/fan# ls -la
totale 0
dr-xr-xr-x  2 root root 0 2007-11-08 07:16 .
dr-xr-xr-x 10 root root 0 2007-11-08 07:15 ..

Please can you send the content of your fan directory?

Thanks
