Unlike the CPU, the GPU does not throttle its speed automatically when it
reaches high temperatures.
Set up GPU cooling by throttling the GPU speed
when reaching 105°C.

Sure, let me update.

Why don't we keep both passive and hot trip points?
Need guidance here, we are keeping passive at low temp so still hot trip
is needed for such cases.
