I found a REAL and SIMPLE solution to my
HIGH-TEMPERATURE problems in Notebooks:
200°F / 93°C was reached when I really got nervous.
At first I thought, my new harddisk or even Linux
is to blame (my first Linux installation in years),
but then the same problem occured in Windows, too.
My \"test\" was simple, I compressed 4GB of files
(a copied XP installation) from an external drive
into a ZIP file on the built-in harddisk
- that heats up the harddisk AND the CPU.
The only way to lower the CPU temperature was to
decrease the CPU-speed to 25%/50% - but that also
decreased the fan-speed. Then I downloaded several
fan/CPU-manipulators, none of them was able to
decrease CPU-speed while increasing fan-speed.
When I read about someone who renewed the \"toasted\"
thermal compound between heatsink and processor,
I actually opened my notebook (after switching OFF!!!),
and tryed to unscrew everything. Fortunately, one screw
refused! I would have broken the waranty seal later...
Then the idea: Blow IN air!
From the outside, INTO the opened notebook bottom.
The fan started to turn with a rather beautiful sound
(turning backwards), and a HUGE amount of dust came
out. 20 months of usage pressed so much dust into the
grating, that the fan could not push out air anymore!
I repeated the above test.
63°C / 145°F is the maximum at which CPU temp stagnates now.
30 degrees Celsius less! The easiest \"repair\" of my life.
I guess I have just prolonged the life of my notebook.
Haaaappppyyy! I am a genius :-)
So now, please repeat this test with your (well used) notebook.
By how much can you decrease its temperature?
bye :-)
