If you bothered reading other threads here then you would know bit-tech don't have a good reputation here..so as far as I'm concerned there results don't matter as they can't be trusted.So it's fair to say you're the one that needs to be doing some reading..
Also what nonsense are you talking about fans, I have an xilence rated at 20 cfm which blows air that you can feel and also other various fans that aren't 60 CFM but you can feel the air been moved..
So I'm not sure where you're gathering your thoughts from but I suggest you gain some real knowledge before you provide information because at the moment it's inaccurate.
