1. Are fans in Mac laptops modular and easy to remove?"
They're pretty easy to access, actually. Unlike the Pavilion dv6 in that video where they're buried underneath keyboard (which requires removing every optional part from the bottom side of the unit) AND parts of the mainboard assembly, all the fans are right under the bottom plate.
Of course, the other side to that is that the shitty Pavilion has a replaceable battery and none of its RAM is soldered in, and it costs a third of what an MBP does.
