Apple put them on the sides (cut into the edge it’s as much on the bottom as it is on the side) as well in the center below the screen on 14“ and 16” MacBook Pro models. Works great, even though the fan doesn’t run 95% of the time anyway, there’s at least multiple spots where fresh air can get in even if one or two vents are blocked.
where else would you put them? with my laptop there’s a big vent across the bottom and you can’t really cover the whole thing with your legs
Even if you can’t cover the whole thing with your legs, I assume they’re designed for those vents to be entirely uncovered.
Also, depending on load those vents can airfry your legs.
