New MacBook heatsinks exposed

We all know about the MacBook's Random Shutdown Syndrome and how it has made many an Apple customer angry. But what is causing all this sadness? Well, a little birdy pointed me to this Flickrstream which contains a few very interesting, and well annotated, photos that expose the truth.

As this photo clearly shows (mostly thanks to the notes) the heatsinks are the culprit here. Originally Apple was replacing both the logic board and the heatsinks of ailing MacBooks, but now they only replace the heat sinks, speeding up the repairs greatly (in theory).
