but what should core temps be? trying to monitor all the temps now.

Having the same issue, bought mine in Sept 12, it was fine for a few months but since Dec. I've been having the same problem.

Sounds like a dust issue try getting some compressed air and blowing out all the fans if this does not work try getting some good thermal paste and applying it to the cpu under the heat synch after cleaning off the old thermal paste using rubbing alcohol and a lint free cloth
