When I contacted the Rosewill rep about sending fans for review she was a bit hesitant, but I wasn't convinced there wasn't something good hiding out in their lineup. Rosewill often provides good products at reasonable prices, so I felt like their lines were worth investigating.

The Silent Wings 2 is be quiet!'s top of the line fan. While our rep (who amusingly enough is my predecessor here for case reviews) wasn't super bullish on it as a radiator fan, the staggeringly low decibel rating and decent airflow and static pressure at least make the Silent Wings 2 a compelling entrant worth checking out. be quiet! as a company has been slowly making waves lately so I've been anxious to test some of their products.

be quiet! is still young yet and like BitFenix they're very slowly making inroads in American markets. As a result the Silent Wings 2 isn't widely available yet, but a quick visit to Google Shopping can find the Silent Wings 2 for a healthy $40.
