I just got 2 new case fans (2xultra kaze 120mm) that are rather loud (45dba) so I bought the NZXT Sentry 2 fan control and the lowest speed % I can get on any of the fans is 40%speed (I suspect 25-30dba).
I figured 40% would of been fine but another 10-20% lower while not really needed would be nice anyway of lower it without buying a new fan control? Guess I could plug them into the mother board (3pin) I'll try that if nothing else will work.
"The fans did not run below 40% speed. This is directly proportionate to voltage. On a 12v scale you'll have 1.2v per 10% that's 4.8v at 40% and most fans will not run below that."
