ok so after a week of using it I notice the whinning noise on my macbok there is also a loud hiss from my adapter. Besides the whinning noises my macbook is perfect. Should I get apple to look at my macbook I heard they are replacing logic boards. The whine really doesn't bother me but if I don't get it fix is it going to damage my computer....also does the whine happen because of a defective part or what? I really don't wanna exchange for another one if there is nothing PHYSICALLY wrong with my macbook.
