Actually right now I'm browsing through fans as I'm planning my WC cooling...
Came across something that just seems bizarre.72CFM
I don't know how that's possible, and at 1400RPM... 120mm... wtf?http://www.silenx.com/ixtremaprofans.asp?sku=ixp-74-14
Also, Silverstone Air Penetrator look like awesome fans. Check them out.
