It gets hot on the bottom, as i can tell on touch, eventually it shuts down.
Also three temperatures are displayed on the panel by 'kima' (kde applet),
i guess from acpi. As far as i have noticed, those temperatures
never reach 50 C.

I do not know how repliable are those acpi temps. They change a little (as
far i have notice), but some times my laptop is almost cold on touch, as 
i rarely use for intesive computation. Most of the time i spend with it is
for reading, writing or web browsing. 
Yet, after hours, quiet and cold, the bottom starts warming up, after more
hours, in a few minutes, fan starts running at the highest speed,  a
writing shows up on the screen: 'critical temp reached' (over 100 C) and the
machine shuts down.

i have checked: fan is running, i can tell by the air jet on my hand

So it the cpu that is overheating
 
Thank you for your suggestions about laptop-mode-tools and hdparm
