Further to verifying things are actually clean, as someone who worked in a warranty depot servicing toshiba/hp/acer machines predominently, the way you blow out your fans and grates is also important! :) Always always best to blow through the grates toward the fan ports, basically making sure air you blow is going opposite to the direction the fans blow. Lots of people force air through the fans, see some dust come out the grates, and call it a day. In actual fact, they have now severely lodged dust bunnies into the inside of the grates, requiring a full teardown to properly clean it. Finally, on my thinkpads, my last t41p i had to take apart 3-4 times in its final years to reapply grease before the gpu finally bit the bucket, that being said I have a feeling Brad has already done all this.
