Description
<3:0>
Normal/Min
Spd 1
Read/Write
This nibble contains the normal speed value for Fan 1. When in automatic fan speed control mode,
this nibble contains the minimum speed at which Fan 1 runs. Default is 0x05 for 33% PWM duty
cycle.
<7:4>
Normal/Min
Spd 2
Read/Write
This nibble contains the normal speed value for Fan 2. When in automatic fan speed control mode,
this nibble contains the minimum speed at which Fan 2 runs. Default is 0x05 for 33% PWM duty
cycle.
