- Pre=applied thermal paste
- Pre-applied thermal paste
- New mfr part number sticker... remanufactured heatsink?
- the main design change is the kapton tape here
- There's a little bit of glue here that holds the cables in place along the heatsink. Upon examination of some failed heatsinks, it appears this is where the short occurs
- Heatpipe thermisistor
- heatsink thermisistor, mounted vertically on the last fin of the heatsink
old and new
the new heatsinks also come with pre-applied thermal paste, which is awesome. no muss, no fuss, wipe it, squish it, and go.
here you can see the main difference between old and new: the old one has the thermisistor cables glued to the gray metal near that little tab, whereas the redesign mainly is the cables being held in place with a small strip of kapton tape

Interesting to see pictures of those! I've had my MacBook fixed for Random Shutdowns not long ago and it seems to have been fitted with a heat sink bearing the same part number as in the photo: 607-0142
Full list of the part numbers used in my repair here.
Do you know if this was the fix used by Apple right from the start or is this new? I find it odd that a lot of MacBooks that were initially repaired for that problem actually had shutdowns only days (in cases hours) after the repair in many cases.

FYI - for anyone looking at this image, these are two different heat sinks and you'll need to make sure to get the correct one. The top one is a 3-wall heat sink, the bottom one is a 4-wall heat sink. I wish I knew this before I bought the 3-wall when in fact I needed the 4-wall.
