It shouldn't run that hot. I suspect you have a rogue application running. Have a look see if anything to do with printers is running. I found this on mine, and about 3 seconds after I deleted the print job, it went down to 30c!

This worked for me! my macbook was running hotter than usual with the fans always going! I had disconnected my printer and somehow I hit the print button twice. I deleted the extra job and it is now nice and cool. thank you!
