I don't think so. Heat from the CPU is going to flow out into the heat
sink, and be picked up by the moving air. Once the air is heated, you want
it to flow out of the case -- not back down onto the CPU!
(The case I'm using for my latest project includes a duct that almost
touches the top of the fan assembly and carries that air away to a vent in
the back of the case so it can't heat up anything else.)
