Thanks for the replies! That scares me deeply that they aren't even listing CFM in their official documentation of the case. I tried to do a comparable search on Newegg of CM fans that had the same RPM and DBA and all of those are listed in the 40s for CFM, but something tells me these don't match that. I'll definitely be upgrading at least one of them to a higher CFM soon. Thanks for the help!
I bought a CM 690 case that comes with 3 stock 120mm fans. For the life of me I can't find anywhere online or in any documentation that tells me what the CFM and DBA of these stock fans is. I'm thinking off adding/upgrading my fans and I want to make sure I get something better than what is there. Any info is appreciated, thank you! E
