It's noticeable, but easily dismissed, especially if you're actively gaming. But users will need to be aware of the air intake and exit points, just like on a PC: air flows in through the green-lined port nestled between the handles, and exits out the grille above the charging port. This was never an issue for me, but those who like to play in a horizontal position will find that their unit gets hot quickly if the intake port is blocked. It can do the same if some program is misbehaving and keeps the processor busy while the SHIELD is enclosed, as in the official carrying case.
