[R] R and computer heat

I noticed the temperature of my laptop rises sharply during execution of a 
long R script that generates several hundred plots, all of them saved to 
files. No screen output. Temps reached above 90 Celsius degrees in the box 
and above 80 C deg in the processor. The machine turns on cooler at maximum 
speed and exhaled air is really hot. Tried similar operations (batch 
graphic and music format conversion) and temp rises were usual.

System: laptop, Turion 64, Kubuntu Linux, Xorg X server, KDE 3.5.9, 
R 2.7.2 compiled with MBCS, PCRE, etc.

Could it be fake due to an interaction of some R piece with system monitors?
