Fitting 4pin female in 3pin male

I have an Aerocool aero-500 which comes with a fan controller that has 3 pin male connector like this one http://imgur.com/DsiPRzy

I accidentally bought 4 pin fans that dont fit in the 3pin male connector. So i cut down the connector and 4pin fans now fit almost perfectly. Picture: http://imgur.com/vSNP3Kh

Is there any danger to it?

  1. I think you are good, no danger.
    4 pin fans are designed for PWM control.
    That is cycling the fan on and off.
    But, they work perfectly well in a 3 pin header but at full speed.

    A 3 pin fan has a + and a ground pin, usually black and red.
    There will also be a yellow lead which is a speed sensor.
    Your fan controller will adjust the speed by adjusting the voltage across the black and red leads.
