SMART FAN
Concept
SMART FAN
W83627EHF/EHG controls the fan speed so that the temperature could meet the target temperature
set in the BIOS or software.
W83627EHF/EHG support SMART FAN
while Pin120 (CPUFANOUT1) pairs with Pin104 (SYSTIN), Pin103 (CPUTIN), or Pin102 (AUXTIN),
which is defined in Bank0 Index 4Ah.bit7~6.
