CFM

I've been looking a some fans online, and I was wondering; what exactly is CFM? I know it has something to do with the amount of air it moves, but how high does it have to be to provide effective cooling (i.e. for a 1.4Ghz T-Bird)?

It's an abbreviation for cubic feet per minute. For a typical Tbird 1.4GHz CPU with a 60mm fan on a good heatsink, you'd want 20cfm or more, in my way of thinking anyways.

Thanks.
So 100 CFM is pretty good then?

100cfm moves the fan from the catagory of cooling device, into propulsion system
