I've been using boinc with my macbook pro classic. boinc basically keeps the processor occupied solving problems for drug discovery. While the Macbook Pro classic was a quiet computer compared to my old PC, i recently listened to a new macbook running boinc. I was amazed at how quiet it was - almost as quiet as my own macbook pro WITHOUT a processor load! What I'd like to know is: Are the new Macbook Pro's similar to the new Macbook's or the Macbook Pro Classics in terms of noise?
