UPDATE:

I changed my web browser away from Epiphany, and this had a radical impact - system runs much cooler.

Also, try hdparm -B 1 /dev/sd* (or be specific which discs you want to power down).

Using powertop could also help.

The installation instructions stated to install Windows 2000 or better.
