This doesnt really mean much, cause fan noise varies wildly from PS4 to PS4. You could luck out or get a silent one (which happened in this case, and is very rare), or you could get an embarassingly noisy one (which is also somewhat rare).
Bet with Intrinsic:
The Switch will outsell 3DS (based on VGchartz numbers), according to me, while Intrinsic thinks the opposite will hold true. One month avatar control for the loser's avatar.
