ok, i've been pondering about this for awhile, without even trying it, as i don't have anything setup currently.

when people use a shroud with a radiator, are they elevating their fan above the radiator so it doesn't physically touch? the advantages to this would be, less noise, and eliminating the dead spot from the fan motor.

if we let the fans sit directly on the radiator pulling air through the radiator and out the fan (sucking), you would be almost creating a vaccum type effect on it. disadvantages: louder, dead spot from fan motor is taking up space on the radiator fins, and what is the advantage?

i think, that since the fans sit directly on the radiator, more air would pull up through it and would be more turbulent, instead of using a shroud to try to get rid of that dead spot...

don't you think? it's logical, and i think would probably only pertain to sucking air through a radiator, and not pushing air through. when pushing air through, that is when a shroud could be most useful.

speculation: fans sitting directly on top of a radiator, sucking air through it, performs better than using a shroud in which the fans are elevated above.
