I don't know what is happening, but I now see that there is no question

I have YET to get it to run hot during general usage. Occationally it
gets above 70degrees. It is REALLY hot (by feeling fan exhaust) now.
Fan is running full speed; or at least that is how it sounds. What is
anaconda doing?
Well, it's installing a bunch of packages. That involves various CPU and
disk-intensive operations. It's reasonable to assume that a system
performing an installation is doing more work than an installed system
sitting at rest.
Are there any decent 'beat up the cpu' test I can run to see if I can
peg the heat?
I am doing screen off tests, so it is running nice and cool right now!
BTW, I noticed that while I was editing just the boot option to pull the
netinst from my local repo, it started running hot. And really nothing
but editing was going on?
There's no particular power management going on outside the firmware at
the bootloader menu, I mean, nothing sophisticated enough to do any is
loaded. It sounds like the firmware isn't very good at heat management
on this system, perhaps? Maybe someone more knowledgeable can correct
me, but AIUI there's really nothing we have any control over here.
There's no power management code in grub that we need to be fixing, or
something.
There is something not right about power management on this system for
sure. Thing is it is hard to find a decent 12" monitor / duo core /
keyb with pointer notebook for cheap. This is now my fourth? x120e and
as much as I dislike them, I have not found anything else that I can
afford. Particularly if I get cut at the end of the month as things now
stand. So I have to work with the 2 systems I have...
Oh, the system is a duo core and I have replaced the 320GB HD with a
240GB SSD.
are you sure you didn't mess up the internals somehow while doing that?
No. It is REALLY easy to pull the drive; that they did nicely. Getting
to the fan, for example is a real pain. Had to do that on the first one
of these I owned.
Probably just a poor design for when the unit is going full out. It
works OK if it is half-way being used, not at full CPU demand.
OK. I will have to work with that.
