For games, do people's rMBP's sound like they're taking off under Windows?
I played quite a few games under boot camp in Windows using my Santa Rosa MBP with an 8600M, but I expect that contributed to the part failing two years later (though it was a known issue with that GPU). It also got terrifyingly hot.
I was thinking about using my new Haswell rMBP plugged into my TV at 1080p or even 720p with the laptop closed. Would it be detrimental to the screen having it so close to the hot metal centre of the laptop? Or can I use just the HDMI out, leave the lid open and disable the retina display?
