Next, we mine for copper, extracting the shiny heat sink. A tall standoff spacer, reminiscent of those found in 27" iMacs, holds this beast in place.

The heat sink offers quite a bit of cooling power in a tiny package:

Heat pipes coming off of each processor (CPU and GPU) flow out to exhaust radiators, each of which has a dedicated fan to blow all that hot air out of the system.

The CPU fan, being positioned not-quite over the radiator, blows down a plastic channel.

The GPU fan is the larger of the two, and its radiator gets a bonus heat pipe that runs from both the CPU and GPU, which may allow for some thermal load leveling.

It looks like Microsoft is getting quite a bit cooler than its late 2000s reputation, if you know what we mean.
