They have some of the highest CFM ratings I've seen out of a fan. I've never actually measured out the rad, so I really don't know what can fit on them.

A high CFM rating does not guarantee that they will suddenly result in better performance than the stock fan setup. A fan's efficiency rating can drop precipitously once mounted close to a radiator; most manufacturer's CFM ratings are gained in an open cylinder without any obstructions.
