I have reset the SMC twice on my iMac 24" (early 2009) and my fans still run at full speed, but only after I've been away from my computer for a while.  It never happens while I'm using it.  Any suggestions?  My Apple Care plan ran out a few weeks ago and so I can't call in without paying. 

iMac, Mac OS X (10.7.3)
