Hooking Two LED fans, need help

I managed to get the white 3 pinned ones hooked up via a case fan controller, but I'm not sure what the best way to hook up the black 4-PIN PMW ones would be. I have a MSI X58M mobo, and I don't believe I have any spots available for four pins. Even if I did, the cable is too short to reach (they're fron panel fans). The fans are CoolMaster JetFlo 120.

I already have these ordered:http://www.amazon.ca/HDE-4-Pin-Molex-3-Pin-Cable/dp/B0081K3ZS0

Don't know if those will work though. I've been trying to find a molex connector that's 4-PIN but they've all been 3 so far, and a lot of them have a plastic casing that would stop it from fitting...

Any advice would be greatly appreciated.

You can hook the 4 pin, to 3 or even a 2 pin connector mate, it doesn't have to be a 4 pin.

Ah, k. It's a shame a lot of connectors (including the case controller) have a casing around the input preventing me from fitting the 4-pin in.

If it works off 2 and 3 pins, why does it have for? Just for future reference, is one of the pins for the LED light or no?
 
One pin for ground, one for +12v, one for sensor (speed reporting) and one for PWM (speed control).

Obviously you only need ground and +12v for the motor to spin and the LED's to light up hence why 2/3/4 pin fans will all work off a simple adapter but they are not able to communicate their speed or change PWM with the motherboard/controller. Not all fans are PWM (pulse-width-modulation) hence most only have 3-pins. PWM allows speed control without changing the voltage. ;)

Awesome! Thank you very much for answering my questions!
 
If you still want to be able to control the speed just pick up a fan controller for a couple bucks.

I was thinking that, but the ones I was looking at had a casing around the 3-PIN, which prevents my 4-PIN from fitting. For example this one: http://www.newegg.ca/Product/Product.aspx?Item=N82E16811992007 - All the pins only fit 3's and wouldn't fit my 4's... My current controller that came with my case is the same way.

I managed to get my 4-PIN ones connected to my Mobo's 3-PIN spots, and they work fine now. But it would sure be nice to find some controllers that didn't have a casing...
 
This fan will go full speed on boot (using 12v with no PWM), making a very loud noise before slowing down when entering Windows. I uses this fan in NZXT H440 and because it's on the back, there's no sound dampening. I guess a bad choice if you are a silence maniac. But the performance is awesome, it can move hot air quickly. I have to tweak the fan to manage cool air for the rad on top, cause the cool air is not getting in fast enough using a H440 case (the hot air blown outside can sip back in through the PCIs holes, well in my case anyway).
