AsRock Extreme 4 Z77 Fan headers

I am planning on buying a AsRock Extreme 4 Z77 and the problem is I am not sure if it has headers for PWM fans. I have tried searching for information about this but I could not find any.

So I want to know if it has PWM support or not? If so how many fans can it take?

The fan I am planning on using; 140mm

Help would be nice.

    It has 3 Case (Chassis) fan headers, 1 of which (CHA_FAN1 located at the bottom of the board) is a 4 pin PWM header. The other 2 are just normal 3 pin headers.

    It has 2 4 pin headers total, but the other is the CPU fan header.

    Edit: There's also a second CPU fan header and a PWR fan header, but they're both 3 pin, as well.

  3. Guess that means I will have to get regular fans or get a fan controller for my 500r.

    Thanks for the help
