This is the trade off. More pressure = more noise. But more pressure means lower RPM will deliver same amount of air as lower pressure fan at higher RPM .. making CFM at dBA with resistance about the same. It's a P-Q curve thing.
Thanks for the constructive feedback , yeah its pretty much how iv always seen it , its not just RPM , as stated in last post , i knew that , just keeping it pointed and uncomplicated , there is always in most things in life a compromise , nothing is perfect , so like you say Static pressure being another aspect vs noise and perfomance, or RPM vs noise , or fan blade tip design , and to cut it short all the other things that make a good fan , Material , bearings , housing , size , manufacturer , preference , aesthetics , requirement , smell and taste , lol ok just kidding on last 2 , anyway , I fully understand what a fan is , and an airplane or jet , and silence or noise , and quite frankly i know i am an amateur compared to you guys , but i do know what is what and what the compromises are , the trade offs , and what i want from a fan and appreciate what others are expecting or are asking from a fan.
What makes the OCN so damn good is to discuss , agree or disagree , to keep an open mind and to learn from each other and be humble , and to have reason and supportive facts behind opinion and points of view ,my previous post is first time i have directly challenged a post so pointedly , i would not have bothered but it is so wrong , not even close to fact , just a n abrasive non constructive answer , that for once IMO requires a response , if the DS was Garbage then just 1 owner would say so , but not one has , that speaks volumes about what an awesome fan it is for what us users of the fan want , which speaking for myself is : Quiet , more than adequate airflow and cooling and Aesthetics , yes this was important to me or i would have chosen some other fan quite frankly, but if you want a great all rounder and a great looking fan then DS is it ! , it smokes my tyres.
