Not necessarily. If the fan just sounds like a jet engine, it's probably 
just a small fan spinning relatively fast. You may be able to get a 
quieter fan, or if your case has a spot for it, a larger fan.

Yup. Thank goodness for automatic thermal shutdown.

Heh. The other day my wife's computer (a notebook) shut down 
automatically, and she couldn't get it to come on again. I picked it up, 
and noticed two things immediately. The bottom was scorching hot, and a 
receipt flitted away as I picked up the computer.

Yeah, a receipt blocked the fan's input port. What really worried me was 
the fact that the computer had gotten so hot that even the pins on the 
VGA connector were too hot to touch! Scary... no permanent damage that I 
can determine was done to the computer.
