I love my black macbook so far-- except for one issue. When I peg both cores at 100%, the CPU speed drops to 1.83 Ghz once the temperature hits 80 C. It then oscillates between 2.0 and 1.83 (but mostly stays at 1.83). Occasionally it drops even lower (1.66, 1.5 or 1.0). Changing the energy saver settings doesn't seem to have an effect.
Does anyone have a cooler runing macbook that actually maintains 2.0 Ghz under full load?
