What's more, they'll arguably move it more efficiently (less turbulence).
However, depending on the design of the cooling system, less turbulence
might not be what you want.

(OK, so I doubt many - if any - manufacturers actually intentionally
design for entrained flow to augment cooling, but what the hell.)
