Yes, I will. They have exchanged a lot of components already though 
(including the whole laptop) and so far, nothing has helped.

This box has been running FreeBSD 8 since day one. It always had trouble 
with high temperatures. But now that summer is coming and ambient 
temperatures are rising, the issue keeps getting worse.

Yes, I am afraid that may happen. Then again, Intel's data sheet clearly 
states that this CPU is designed to operate at up to 100°C.
