Great work Tator!
I had no idea that the published specs on some of these products could be so misleading. Nice to see someone taking a more scientific approach to help the rest of us educate our fan choices.
I'm dying to see more results from the 120s you have (especially the Cougar Vortex 120 pwm as they are $9 on newegg today). Some intake fans are the last few things I need to complete my quiet rig, which is also my first build in over 10 years, so I'm itching to get it finished!
I have a question that may be a little off topic... Tator and others have alluded to pwm fans actually having a different sound quality than voltage controlled fans, can someone elaborate on this or point me to some info about it?
