My laptop started to have heat issues a few months ago, but I tracked it down 
using a temperature monitor widget and to see the idle temp and watched it 
climb as I did my normal things until it froze and crashed.   I powered it off, 
then found out my canned air was empty, so I pressed my mouth to the vent and 
blew.  A stream of dust shot out the other vent all over my second display.  
Powered it back up and the idle temp stayed low and did not climb much under 
load.  Have not had a crash in months.
