Lots of talk about fanless MBAs. I don't see how it's possible. I have a new 2014 11.6" MBA which has the lowest power CPU/GPU of the range. Normally it runs very cool and it might be able to run without the fan. But if I run a compute-heavy task, the CPU gets up to 80C in about 10-15 seconds and it hits 90C and the fan spins up to a pretty good clip after ~60 seconds. Now, Broadwell is supposed to decrease power consumption by 30% over Haswell. That's great, but surely the current MBA's fan improves cooling by at least 30%. (Remember, it always runs at 1200 RPM or more.) So I would expect a fanless MBA with Broadwell to hit the same CPU temperatures as the current MBA. Might be fine for light use, but under heavy use there's no fan to spin up, so it would have to resort to major CPU throttling. Which basically means crap performance if you're doing anything serious. I can't see Apple going down that route for one of its nice, expensive laptops.
