This one is what I am talking about. According to its spec, from 20CFM@17dB up to 52CFM@43dB. And it is only 5 bucks. It seems like it does have good feature compare to other adjustable fan, like YS-Tech(10.2CFM@18dB~48.7CFM@39.5dB) or Enermax Whisper(18CFM@18dB~31CFM@34dB), and it's only about half price.
Is it just a kidding by SVC, or a fact? Has anyone used it?
