Hi, I am considering to get a 27 Inch iMac, 3.5 Ghz i7, 16 GB, 512 SSD, 780M GPU. What I am not sure about and difficult to test in a store: how loud does the comp get under continous 100% CPU load, like for 30 minutes? There is also no GPU load that might cause heat, just 100% on CPU. My issue is twofold: the noise would irritate me, but in addition really loud noise (like from my current Windows Notebook) would be bad for the sound of the recordings I make. You really hear the fans spinning up and whirring with my current machine. Note that I only record my voice, no other sound. I have read a couple reviews but it did not provide me with a clear answer. Do you have any experience with it? If the noise is too much of a problem, the new Mac Pro might be an option, as it seems to be really quiet according to all reviews.
