Because Scougar want it to sound like a PC!....Not a F15 on the number 1 catapult!
You can actually get to the stage were no matter how much air you blast at it ...cooling differential doesn't move much any more. OLDFART!...Your mouth in gear first comment of "I'm afraid you have it all wrong" did make me laugh!...Let me explain..... All the laws that apply to fluid dynamics , apply to air, the property's and characteristics are the same. Forgetting about maximum critical flow limits for a given tube/hole size.......The difference between a 1" tube and a 2" tubes ability to deliver a fluid is 8 times.....that is, a 2" tube has the ability to deliver or exhaust 8 times more fluid/air. "FACT!"
Of course a 180mm fan will eat a 120mm fan for breakfast......It's not rocket science!!!
But when you change a fans characteristics to perform a given task (Penetrator) regardless of size......there has to be a design trade off....Better focus of air stream means you have to take a hit on DBA (noise) or CFM (volume) or even both. The golden approach is be to make (pick) the heatsink that's more efficient for the air to act upon..........And the magic bullet is getting the hot air "OUT" as quickly and efficiently as possible, not making a computerized hovercraft
