fan question 4 pin?

i am looking for 3 120 mmfans that i can plug into my mobo and control the speed at witch they spin. I do not want a fan controller. I want to plug them into my mobo and control the fan speed through the bios. But i am having the darnest luck finding the name of this connector. I belive the 3 pin is without the pwr function but a 4 pin is a molex to my understanding. I want it to be 4 pins that connect directly into the mobo. What is it called?

Is this what you need?
