kded was using 90%-95% of total usage.

http://processorfinder.intel.com/details.aspx?sSpec=SL79L is probably my CPU,
with a design spec of 69.1C.

Comparing AMD to Intel regarding temps is pointless.

The box only runs SUSE. I don't play games on any box, and don't know
anything about Doom.

I built kernels on it a while back. IIRC it never touched that level of
temperature or CPU usage. Kernel building is a lot more disk I/O dependent
than I imagine kded is.

They're not all the same. The one I have (Prescott @ 3.0GHz) is one of the
most effective heat generators of them all.

Months or a year ago it had a problem with heat generation, and I
underclocked it several weeks to solve the problem pending a new CPU cooler,
which stopped the beeps and stopped the random BIOS overtemp-forced shutdowns.

The cooler is supposed to be good enough for 3.6GHz. The fans are all working
as designed. The problem does not occur under normal usage, only when a
runaway process works the CPU intensively.
http://lists.kde.org/?l=kde-linux&m=122904262017936&w=2 is a reply to my same
question on the kde-linux list that offers an apparent solution.

The ultimate solution is system replacement. I already built it weeks ago. I
just have to get an OS chosen and installed, the former of which has been
proving difficult due to my mandatory requirement for X to have functioning
panning virtual desktops, AFAICT missing from openSUSE 11.0 & 11.1 and other
xrandr distros released in the past year or more.
