This is great news for people who want to clean their PS4 Pro from time to time. The entire top protective shell is not held together by any screw, you just need to carefully un-snap it from the main body of the console. Removing the top protection gives user full access to cleaning entire fan.
This was shown in the official Sony PS4 Pro teardown video:

And confirmed again by iFixit during their teardown:
- "With the beast on its back, the opposite panel pops off after some prodigious prying—but no "warranty void" stickers!"
- "While you can't remove the fan, you could certainly clean it from here—maybe that's why we're granted this non-warranty-voiding access zone."
Changing the termal paste is another story of course. Full disassembly is needed for that.
