Simple poll here. I though I would post this because I'm currious just to see how many macbook users here have the dreaded "moo". for those that dont know what the moo is its the fan turns itself on and off in intervals of a couple seconds, creating a on and off wirring type noise. Incase your wondering my blackbook does moo Seems to happen right when it reaches 67C. I also have the wine during idel processes but its not realy much of a wine more of a hiss sound.
