We have a heat wave in Portland. It is 100 degrees and I turned my computer off when it's fan started running continuosly. I killed a similar computer earlier this summer under like circumstances. Is there a danger zone when computers will overheat?

Usually the problem is the internal fans overheat (removing excess heat from the CPU, video card and motherboard, etc.).
Easiest solution is to remove the cover so the airflow can cool the internals. You can always point a room fan at the computer to move more airflow. Also make sure you have emough room around the computer case for air to circulate and that the intakes are NOT dusty (a very BAD sign).

My real-life job is actually as a computer support specialist. I have to kindly disagree with some of agitprop's advice. There was a time with early computer designs where it might have been true. However... with most modern computers, the casing is actually an integral part of the cooling system. The components are placed strategically within the casing so that the fan, and heat sinks can work efficiently. Removing the casing simply makes the fan work harder in most cases.
However... his suggestion to make sure that there is room on all sides of the case for circulation is a very good one... along with his recommendation to make sure that the intakes are not dusty. In fact... I'd take that a step further. Open up the case, and use canned air to blow out ALL the dust from the internal components. (especially the fan). The fan typically has a thick layer of dust on it... and by removing this, you're taking weight off the fan, reducing the strain on the fan's motor. Plus, if there is dust on the heat sink(s) removing the dust there will make them work more efficiently.
