If anything, it's a bonus to have the fan so your can have prolonged boost performance while the MBA chip will throttle under continuous load.
I think I would rather take a small performance hit and some heat than have Apple quick to pull the trigger with a fan blasting noise as I’m trying to focus (if yield comparable stats).
Will wait for more info. If this chip is really that much more efficient hopefully we are back to the good old days where MBP fan is tolerable. Otherwise I’m all in on Air
"Make it thicker and heavier" is apparently not the answer that Apple was looking for from Intel.
Thin and light Wintel PCs are known for having a lot of thermal issues too.
