I'm looking into quieting down my system and obviously I first turn to replacing those noisy POS fans. I see Panaflos have readings of low, medium, and high... despite the fact they r panaflos are the highs or even mediums even audible? I"m looking to have a 80mm intake, 120mm outtake and 92mm on HSF all panaflos. I want the system to be near silent but I want good cooling since I overclock.
