Hi Phil,

imagine you are an expert in the area. Then imagine someone sends you this
e-mail. Do you think you would be able to help based on the information in the
e-mail ?

Or, in other words, please provide sufficient information for people to actually
be able to help. Kernel version, lm-sensors version, complete sensors command
output, and all relevant configuration (including pwm configuration) would be
a start.

Thanks,
Guenter
