have to here with 4 120mm models, Corsair and you can hear it even through the headset by if you do not fully turning up ... for have GPU and CPU (970 and i5) always less than 45 ° and that without wk I let them first drinne. .. SpeedFan does not work with my mb so would ne fan control advisable but since it was previously with 3 standard fans just as I do not care: D may also be that it is on the MB but even for 100% rpm which is loud but what I expect at 7 fans XD
