Over the last few week my Black macbook, 250 gb hd, 3 gigs of ram, has been running loud and hot. the second i log in the fan comes on to over 6,000 rpm after about 15 minutes it gets up to around 200 degrees F. i called Apple we did a command option p&r that did nothing ive tried reseting the smc still nothing. im kind of running out of ideas. nothing in activity monitor is above 3 percent usage of my cpu. and ideas?

EDIT: ***FIXED***
If any were wondering how i fixed this, I opened system preferences-print&fax-and clicked on each of my printers. opened the queue and found 1 document that was trying to print i deleted it and the fan stoped in a bout 30 seconds and the temp dropeed to 100 degrees
