Which MacBook doesn't have any fans? I'm looking to buy a MacBook Pro (13"), but I want it to be as quiet as possible.
So, which MacBook Pro doesn't have fan? Only the Gen-5 Broadwell CPU?
The recently announced 12 inch sized retina screen MacBook (Early 2015) will be the first fanless MacBook to ship once it goes on sale. 

The MacBook Air (11" &amp; 13") and the MacBook Pro 13" have one fan, the MacBook Pro 15" has two.
