Just wanted to give an FYI on a product I just purchased that turned out to be total crap and to keep other people from making an wasteful purchase like I did. I wanted to replace the stock fan on my Dark Knight HSF as it was making a high pitched buzzing sound that I was getting tired of hearing. After some newegg searching I found these new fans from Xigmatek and decided to give one a try.

BAD idea. The fan even at low RPM makes a terrible and loud "wooshing" noise while on my HSF and when the RPM ramps up during loads, the fan sounds like a horrid jet engine, far far worse then my stock Xigmatek fan ever sounded. It must be due to the stupid new fan blade design or something, but I claim total false advertising on Xigmateks part because this fan IS NOT quiet by any shape or means and is a total waste of money if your looking for a quiet all purpose fan. Just pass on this one, you have been warned.
