I run a MacBook Pro (15-inch Unibody, Mid 2012, 2.6GHz Core i7, 16GB, SSD, GT 650M 1GB) on an external 1080p display. The computer runs quite hot while doing light tasks like watching 1080p 60fps youtube video. I like it silent and the fans' noise bother me.
I have always taken great care of this fine piece of machinery. Thermal paste application is renewed, fans are dust free and I use the Rain Design mStand.
I bought a spare bottom case to drill some holes to better feed cool air into the fans. It's easy to find the center of the fans on the bottom case with the help of geometry. You can take the mesures directly on the mobo with a compass between the pogo pins and the centre of the fans. Then report the mesures with the compass in order to build a triangle from the marks left by the pogo pins on the bottom case. I uploaded the holes template as well.
The drill bit is 3,2 mm in size and made for metal/aluminium. I drilled them inside out to prevent scratching the exterior. I will see in the future if a dust filter is mandatory or not.
I'm very pleased with the results (temperatures in C°) :
CPU Temperatures stock bottom :
Idle : 60° fans : 2000 rpm

I hope this helps someone.
