I have an MBA 2012 (i7/8GB/256) and have to admit I have been pretty disappointed with the fan noise since I received it around a year ago. Doesn't take a whole lot of work on from a simple running program or two before the fan starts kicking in. And it keeps on going. In a lot of the the threads here there are mentions of speed, but not so much about heat and fan noise. Since the MBA 2012 i7 was noisy like a jet, I'm wondering how the new Haswell 2013 MBA would do. - Are they running cooler than the 2012 MBAs? - Is there any difference with fan speed with the Haswell i5 and i7? - Anyone noticing fans kicking in with their new MBA?
