[ltp] Safe X60 temperatures?

Hi Richard,

I have no definitive answer to your question. However, I recognized similar 
temperatures on my wife's X61Tablet. This machine seems to be build for the 
sibirian market ;-) 

In the past, she actually had overheating problems as Linux enforced an 
immediate shutdown several times and she had to wait about 15 minutes 
afterwards before she was able to reboot. The situation seems to have become 
better since she did a BIOS upgrade three months ago which has modified the fan 
control algorithm according to the changelog. Maybe, this is an option for 
you, too. However, she still notices temperatures up to 80°C although no more 
overheating shutdowns. We are still investigating this issue. As the machine 
is getting three years old within the next months, it might be useful to check 
if the fans are covered with dust.

Regards,
Stephan.
