I recently added a crapload of fans to my case, and I ended up with two Akasa Viper fans on my H90 radiator, which rocks, and because I didn't feel like spending $20 each for 9 other fans, I bought Rosewill Hyperborea fans from new egg, which are rebranded Akasa Apache fans. I have zero complaints about them. They're quiet, no clicking notable from any distance past 1 foot, long cables with PWM, they're black (I'm not a big fan of orange, gray, yellow, etc, but I got the vipers because they appeared to be the best fan for radiators in 140mm).
I am disappointed that my case intakes with honeycomb mesh are pretty loud when there is a significant amount of airflow, but that's case design and definitely not the fans fault (unless you fault the fans for having too much airflow). I never realized how badly regular fans blow air every which way until I got these, they blow air in a linear fashion, straight at whatever they're pointed at.
I used to "splurge" and buy Yate Loons for every new build, but now that I see such a quality difference in construction and performance, I don't think I'll ever use a Yate Loon in my main performance PC again. I may use the few I have laying around in a computer I really don't care about, but my opinion of them has changed significantly.
