Fanspeed files not found !!

[Kooothor]

Hey folks,

I need some help before my macbook burns !!

Everything used to be fine, my fan used to go at 3000 RPM
But this morning I accidently booted into osX, and now with the command "sensors" I can't get any fanspeed output !
The cause is certainly because I have no more fan* files into my /sys/devices/platform/applesmc.768/ folder....

and I can't create them as I see : No such file or directory

HELP pls !

a ls -a of this applesmc.768 directory shows this :

ls -a
.          key_at_index              modalias      temp1_input  temp7_input
..         key_at_index_data         name          temp2_input  temp8_input
calibrate  key_at_index_data_length  position      temp3_input  temp9_input
driver     key_at_index_name         power         temp4_input  uevent
hwmon      key_at_index_type         subsystem     temp5_input
input      key_count                 temp10_input  temp6_input

Any help appreciated !
