    2323Pick a divisor so that the nominal RPM is about 50% 
    2424above the minimum. This is a good compromise between 
    25 margin and accuracy. 
     25margin and accuracy. Note that most chips only support 
     26fan divisors of 1, 2, 4, and 8.

     39- How to change fan divisors: 
     40 
     41  Method 1: "echo x y z > /proc/sys/dev/sensors/...../fan_div" 
     42  where 'x y z' are the fan divisors for the three fans and '...' 
     43  is the sensor in question. 
     44 
     45  Method 2: Put an entry "set fanx_div y" in the appropriate section 
     46  of /etc/sensors.conf and rerun 'sensors -s'. 
     47  (x is the number of the fan 1-3 and y is the divisor).
