We have in the house now 2 macbooks (white & black) and a MacBook Pro. All three machines are 2ghz Core Duo - 2gb Ram The white macbook seems to hover around 55c and can rise to 75c when on full load. The black macbook fares a little cooler with temp hovering around 51c and can also rise to 68-72c on full load The macbook pro is so much cooler. It seems to hover around 40c and rises to 55c on full load. And to add to this - my macbook pro is additionaly inside a clear speck shield case which would increase heat you would have thought. Even with SMC fan control 2 - my macbook pro at 1000rpm remains around 40c whilst surfing etc, and yet the macbooks are 50c + and are at 2000-3000rpm So my question is WHY ? Is the cooling solution in the macbook pro so much better, or is the macbook a simply a very flawed design.
