Fan Connector Switch

post #1 of 14
Thread Starter 
I'm in the works of planning a new build and for intake fans I want to use Scythe Gentle Typhoon 120 mm - 5400rpm. Yes I know they are loud, why I plan on using a fan controller and a headset. The default connector is a 4pin Molex and a 3pin fan connector with just the RPM cable connected.

My question is, can I pull the hot and ground wire out of the Molex and slide it into the 3pin fan connector then it work correctly with a fan controller. Also, plan on using two of these fans on one channel, shouldn't be a problem, no?

Yes, but you can't simply slide the cable in, it will not guarantee to have or contact at all when plugged to 3 pins male header of the fan controller. You will need to solder or clip the cable with the pin as in the female connector.

You can use 2 of these fans on one channel if it is rated 40W, as each the fan at start-up will pull 1.76A = 21W.

I figured id have to take the metal part off the wire, then strip away some sleeving then slide it in and crimp it in there. Would that work?

Dang, power hungry little things.. Do you know of any 40W controllers, Ive only seen 30W controllers around.

Lamptron FC9 -> 50W per channel

Lamptron Hummer 5 Port -> 100W per channel

Lamptron Fan-Atic 5 Port -> 60W per channel

Lamptron FC2 -> 45W per channel

I think that's it for high powered controllers.

Thanks for the list of controllers.
If no one does it the way I'm talking about, how do y'all connect these fans to a controller?
post #6 of 14
I cut the wiring cable of 3 Pins and the cable of the fan then soldering each cable. Or you can buy molex-to-3pins fan adapter. Each about $3.49. Go to www.koolance.com under accessories, you will find it there. I am on mobile device can not link it for you.

Here you go...

3-Pin / 4 Way "Y" Adapter --- Connect up to 4 fans to a single channel on a fan controller.

Would you mind taking a picture of your handy work so I can get a better idea on how you did it? The 5400rpms have a molex and 3 pin already connected to it, the 3 pin has the yellow wire in it for the rpm reading. So, i was thinking of taking the hot and ground out the molex and putting it in the 3pin. Sound good?

I use the female 3 Pins as shown in the picture, cut the cable about 3" from the end and join each wire to the tach line, ground and +12v with the fan wires.


Altenately, you can simply use this adapter

Wouldn't I use the male connector? Be from male connector off the fan to female connector from a Y splitter into the controller.

I was gonna use these to split the power and connect more fans to the controller.
