Today, Apple released SMC version 1.1 for MacBook Pro machines that especially Retina owners will like: it fixes their fan issue that has been present for months, but caused some stir lately.
Apple rushed this update. In fact, it is so new, not even EFI and SMC firmware updates for Intel-based Macs lists it.
It affects both mid 2012 and early 2013 models.
This is how to update:
I had the same problem with the basic installation. Just do the OSX updates from the App Store and the problem will disappear.
Lots of users are reporting the below SMC update fixes the fan issue.
