"Tripled" a 4-pin mainboard contact with a cable, the signal for the revolution of the fan there infected on the board returns. Have so the CPU fan in combination with 2x 12 cm (front and rear) and 2x 14 cm (up to a Corsair 200 housing) Arctic PWM fans, which can also pass the control signal up and running. Interestingly, "bring" the two 14er top of the housing the most. They run nice and slow and quiet and shovel the warm air out. After I installed the top, the rear fan had considerably less to do and everything is calmer. Absolutely silent the whole thing is of course not, but provides excellent cooling and idle it roars only very little. At full load `s louder, but adheres completely under.
