the four pin connector IS for your heatsink fan,the fourth pin is for the pwm on the fan motor,like on p4 cpu fans.if yours only has three,then you can still connect your cpu fan to it.you just need to use one of your other fans 3 pin conectors to get it on the correct way,with one pin unused.it should only go on one way.in my bios i can switch it to pwm or normal(no pwm on fan)mode.

the cas_fan one is for the front or rear case fan.again on my board,the bios can control the cpu and cas_fan 1 speeds.
