I'm posing this question because my current Late '11 machine has really begun to annoy me. 80% of the time I use it docked to my Thunderbolt Display, and the fans are running on full blast. I remember when the rMBP was released, it was talked about how the fans were differently designed to be quieter. Is this true, and are the fans notable, at least when compared to an older Unibody Pro? I looked online last night and my local Best Buy has a 512/16GB model open box. If it really makes a lot of difference, I may purchase it. Thanks!
