The outer shroud is only needed for the directional flow of the outlet air. It will suck just as fine without it.
In essence they are not all that different to a turbo-impeller, which is great for sucking air in.

Humm, what if you used a good Heat Sink on the CPU and somehoe duckted the "suck" part of the blower to the HS to pull air through it and have the other end ducted out of the case? Basically like a vacum cleaner sucking air through the HS. Seems to me that would pull fresh cooler air around the socket and mosfet area's aswell..... Maybe a better idea for a Air cooled TEC...
