Potentially silly question, but have you changed the thermal paste? The stock paste used on these machines isn't very good, and if it hasn't been changed, it's almost certainly flaky and brittle by now. A fresh blob of Arctic Silver should improve thermal performance. Also, consider cleaning out any dust from the innards!
