Case Fans and MOBO

[azeem40]

My case is a HAF 912 and my MOBO is an Extreme4 Gen3 Z68. How many fans could I use depending on this?

The board would appear to have space for 6 fans(4 pwm fans and 2 3-pin fans. PWM fans will work on 3 pin headers and 4 in pwm fans will work on 3 pin headers. PWM adds better speed control).
You can use other fans connected to the power supply, The limit for fans on the power supply will be the limit of fans you can fit in the case
