"for both coolers combined with one or two fans the sound levels are just not an issue. With the lwo RPM fans both the NH-U12S and NH-U14S under normal operation are silent, even more silent then liquid cooling. I can write an entire paragraph about this fact, but let's just call it what it is and get it over with, the noise levels are darn good and thus extremely silent, even with two fans in push-pull configuration noise should not be an issue whatsoever."
