Appetite whetted, we pluck out the Book's GPU board assembly and its attached fan.

We find a suspiciously Mac-like heat sink mounted to the base's GPU.

Wow, this is really giving off an Apple vibe.

We've always said we could use a few more fans. With the heat sink out of the picture, the base's 0.30 Amp model is ours for the taking.

That would have been a lot of work just to clean a dusty fan. Let's hope that never happens.
