Thanks Karl for your reply.

The Thinkpad T420 laptop is an ex-government disposal unit which I've 
owned for 4 years, it's actually 11 years old, and it's overheated form 
the start. As I say, there is no dust inside (it's just a matter of 
removing the keyboard, and the cooling section is very easy to clean). I 
have increased the RAM from 3GB to 4GB and the fan runs at what I judge 
to be a normal speed although it doesn't seem to increase in speed as 
the temperature increases. I have also tried different desktop 
environments with very little noticeable effect. I'm currently using XFCE.

Backups and watching YouTube videos cause the laptop to run so hot that 
I cannot hold my hand in front of the vent, I normally cease watching 
YouTube before then.

Closing Thunderbird does extend the time before the temperature 
increases to a dangerous level but even so I can only watch Youtube 
videos for no more that half an hour (I download longer videos and watch 
them on the TV).

I'm about to install lmsensors again so that I can check if the fan 
speed does increase with the temperature.
