Don't know but,
It would be hard to test. The elicent (never heard of them) is a centrifugal, and the can max is axial hybrid type. It would be different in different scenarios. Centrifugals are better under higher pressure.
After looking on the can website they make a q max 12 inch fan that has a built in silencer. It flows less, and I don't know if its a gimmick or not.
I'm partial to vortex fans, they have a website and post there ratings with graphs and air flow under pressure and post Decibel ratings.
