arctic cooling F12 is a decent all-rounder fan. silent, decent cooling (unless youre into those 1800rpm above fans), decent airflow, and its less than 10usd a piece. not sure if white/black color scheme would fit your case.
i use those overpriced scythe kama flow 2 or s-flex (both 1800rpm) because i got it in an ancient computer store for very cheap. they are noisy at 1800 rpm though, im guessing its the motor/bearing is causing the noise. if i lower the RPM to 1200/1400 they are quiet enough for me.
the hyper212 evo dual fan is great, but note that the stock fans from it are noisy as well. it is even noisier than the scythe fans that i have if i use it at 1800rpm. the fans are not as noisy as the stock cpu cooler though!
