heat transfer in tablet enclosure/case

Hi,

I want to ask how to make a simulation of thermal forced convection in the tablet enclosure. Attached is the screenshot of simple surface pro tablet's 3d model. What type of analysis should i use, internal or external? the problem is how can i setup cooling fan which located inside the tablet case?? can we make natural convection from this model since it has 2 unit cooling fans??

anyone who have idea or thought on how to do this, please comment.
