I have also a P4 2.8 GHz in my Medion Laptop...
When I just sit on the PC and work (with quite some programs open), the
temperature stays at about 46 degree and everything is ok.
But when I start some bigger compiles, the processor gets very hot.
After 5 minutes I have more than 70° and the highest I saw was 75°
The critical point isn't yet reached according to acpi:

cat /proc/acpi/thermal_zone/THM0/trip_points
critical (S5): 85 C

But I don't like it anyhow (the laptop is really hot in this area where
the cpu is...)
So I throttle my cpu when I do any compiles so that the temperature
stays at about 65° (I think it's a lot better for the lifetime of the
processor...)
I wrote a small script to make things a little bit more easy (and
configured sudo so that I can throttle my laptop as user):

cat /usr/local/bin/throttle
# !/bin/bash
if [ ! -n "$1" ]
then
echo "To set throttling state, type: throttle [0-7]"
cat /proc/acpi/processor/CPU0/throttling
else
echo "$1" >> /proc/acpi/processor/CPU0/throttling
fi

And then I configured gkrellm2 to run this script automatically when 70°
are reached (additionally my laptop begins to beep at 68°) - very useful
feature.
When I compile at night, speed isn't that important and you can still
work with 50% throttling (but you'll of course notice it), but I
consider buying a notebook cooling pad (if it can cool about 8-10 degrees)
It's okay for me now, but I don't think I will buy a laptop with a
desktop processor once more...
