I have an Portege R500 series notebook with U7600 processor, and would like to know what other users average operating temperature is for normal desktop use i.e. word processing, watching DVDs/youtube, surfing the net, etc.

I'm asking because I've recently bought a second-hand dock (port replicator ii), and also upgraded the OS on the laptop. It seems to me that there may be a problem, because under heavy usage (compiling software) the performance seems to degrade on the machine - only solution seems to be to power off the machine and leave it off for a few minutes.
Even when I'm not doing anything heavy - such as typing this post, the CPU temp lingers in the high 80's (celcius).

I've seen on the forums that other people have had problems with overheating on this laptop model. My machine is about three and a half years old. I've opened it up and cleaned the fan with compressed air, and verified that it actually spins when powered on. However, I don't feel much airflow if I put my hand next to the exhaust when it's on.

Can someone confirm if the exhaust is supposed to s u c k or expel the air? Can you confirm your average CPU temps? Anyone know of issues with the dock that cause overheating?

Thanks in advance!
