Laptops overheating.

[SteveBuscemi]

For the record, I'm running a Dell Inspiron 1150.

How hot can laptops get before they overheat?
What are some signs warning that they are going to overheat?

My laptop heats up to around 70 CPU, 80-90 GPU (Celsius). That's a lot hotter than a desktop, but it's OK, laptops get hot. A good thing to do is buy a cooling pad. I have one (and to make sure, I put a bunch of case fans behind it powered by a 9V transformer) and it cools my laptop pretty well.
