RW +There is a third case where trip points are associated to both PWM output +channels and temperature channels: the PWM values are associated to PWM +output channels while the temperature values are associated to temperature +channels.

When several temperature inputs are +mapped to a given PWM output, this leads to several candidate PWM values. +The actual result is up to the chip, but in general the highest candidate +value (fastest fan speed) wins. + **************** * Temperatures * |
