As I have already stated, changing the power management options didn't change
anything at all. Even running the "low" profile doesn't stop the fan from
cranking up to full speed under normal desktop load and never spinning down
again, even if the system is idling.

I am also most certain that my laptop has a separate GPU fan; I can, in fact,
control the CPU fan per sysfs, but whatever I do, the GPU fan keeps spinning at
the same speed, so I guess there must be separate fans for CPU and GPU.
