Wanted to show a short video I made when re-assembling my case after the AF120s arrived to serve as case fans. I was impressed when I got them working, they move a good amount of air and produce almost no noise. But one thing still got me thinking... the CM R4 fan I had on the CPU cooler produces even lower noise than the AF120s, has more static pressure and just by feeling the air moving it looks like it moves more air too! Then I ran a homemade crappy test to figure things out: video The CM R4 fan performed so well compared to the AF120, and everyone seems to hate CM fans for wtv reason, calling them cheap, crappy fans which don't suck much air at all, going in an opposite direction from my experience with this particular fan (~ 1 year old). The CM fan I am using is this one, rated at 90CFM (doubtful). Am I seeing things wrong? What you guys think?
