Hi all,

I'm helping my son build his first PC and have come across an issue.

Hes got a case with an RGB controller
https://www.amazon.co.uk/force-gami...=CIT+rgb+case&qid=1565808482&s=gateway&sr=8-4

The controller of which has 6 pin RGB connectors like these

The problem comes with the cooler:
https://www.amazon.co.uk/DEEPCOOL-W...9Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU=

Which uses 4 pin connectors for the fans and pump.

Any suggestions on a solution, Ive had a look for 6pin to 4 pin adaptors but cant seem to find any.

Thanks
 
12V LEDs have 4 wires:

+12V supply
Green ground/negative
Red ground/negative
Blue ground/negative

So out of your 6 wires you'd need to split those 4 and supply them to the cooler for lighting.

If the pump has 4 wires, they will be:

Ground/negative
+12V supply
RPM (speed) reading signal
PWM speed control signal

So I'm not sure which is missing, but I suspect there isn't a speed reading wire in the 6 pin cable.

You'd need to identify which wire is which and go from there. It may be easier to find third party LED control - it's often integrated on modern motherboards. What motherboard does he have?
 
Thanks for the reply,

Hes building it with pocket money so the motherboard is relatively old, its an ASUS Z97-P and as such doesn't have rgb headers. The plan was to use the RGB controller that came with the case.
 
Ok, you can work out most of the wiring using a 9V battery and a couple of wires. Happy to help figure it out - it's basically a case of "Try pin 1 with pins 2, 3, 4, 5, 6 then try pin 2 with 1, 3, 4, 5, 6 etc" :)

Remember to note down what works, and at what polarity! You should end up with 4 facts:

- the pair for red lights
- the pair for green lights
- the pair for blue lights
- the pair that makes the fan spin

That will let you know what 5 wires are - the 6th wire will be either speed reading, or speed control, and we can probably work that out too if you have a multimeter.
 
Ive removed covers on the controller and the 6 pins are marked + - + G R B
What are the two +'s?
On the 4 pin connectors they are just + G R B

Also the 6 pin connectors seem smaller than anything Ive got, they are closer than a normal header spacing, any idea on the name of the connector?

Thanks
 
No idea what the connector is TBH. But I would speculate you have:

Variable + supply voltage for fan speed, and a ground

Then

Standard 12V "+,G,R,B" LED wiring. So that at least should do for the LEDs.
