There is an update on the HP website for the BIOS.
I do believe that I had updated it the last time when
I posted this problem. But I will check again, and if
it is not latest, I will indeed install it via windows 7 (on partition 1).

What I am thinking to do now is not only to gather the lmsensors
data, but also to use a fedora (20) package to reduce the frequency
(and hopefully, thus the temperature, of the cpu. Perhaps that
will go a long way to alleviate the problem.
