First I would like to share that I am rather user of a computer than someone 
who is into the very depth of it. Installed by chance Kubuntu some 2-3 yera 
ago and by far I found it much more user-friendly, adjustable and less 
consuming by any other OS I've tried before.  I did a fresh install on my main 
machine that was upgraded only sice the times of 8.04.  The same reason -- 
thought that after some years of using (and also trying things) it started to 
run not so smoothly.  Got now some of the issue you are observing.

This I have noticed by the more often switch on of the fan.

This is particularly annoying.  I attributed it to the visual effects that are 
enabled and some people of this list advised to use different ones.  Indeed 
worked,but I lost some of the beauty of the KDE.  Now the effects are on and I 
have to scroll up and down several times before being able to see what is on 
the screen...

Don't use that as I primarily need .doc format for documents.
