Haf x led button

post #1 of 5
Thread Starter 
I wanted to know if there is anyway to mod the led on/off switch on the haf x to make it control more than one fan's LEDs. Thanks in advance.

Yes of course it is, I'm not 100% sure how but on my cm storm scout I remember having to add a resistor then hooking my fan leds to that, it all depends on exactly what you want it to do.

I will be pulling mine apart later today, as I want mine to control multiple fans and leds hooked up to a relay and ir control, so if you let me know exactly what you want the switch to do I will help you out :-D

I just want the front switch to be able to control the lights on the other 4 fans I have.

Ok I will explain quickly but beware with standard fans this is not easy

First off you will have to pull of the sticker on you fans

Now depending on how the switch works will determine how to do this but if I remember rightly the front fan has 2 wires coming from the switch which means positive voltage and ground

So with the sticker off you need to unsolder all leds and connect together each negative of each led and then the same for positive

Now there are a couple of different ways this could be done depending how the switch is wired up. If 5v comes from the switch and the positive side is switched you could easily connect ground from leds to ground input from fan connector and then run 1 extra wire from the positive of the leds through a resistor and then to the switch

Another way this may be done is 5v which switched negative, this way most likely easiest as you could leave positive of leds connected to fan and simply disconnect negative and solder them together and run them to the switch. This would work but if you turn voltage down on the fan the same will happen to leds although you could still connect positive to the switch through a resistor

The switch could be 5v with both positive and negative switched in which case you could do any of the above

Or it may be 3v switch in which case you could do any of the above but you would not need a resistor

I will look into it when I get home and let you know for definate how to do it

Ok as an update I have looked at the switch and I now know that the switch has constant 12v on the black wire and switched 12v on the red wire, but this will be reduced if used with a fan controller

So to wire up simply disconnect all leds, connect all negatives together and connect them to the ground input of the fan then you have 2 options, you could:

A. Connect all positives together and connect them to the red wire from the switch through a 120ohm resistor with at least a 1w rating

B. Solder a 470ohm resistor to each led then solder them together and then connect to the red wire from the switch

I hope this helps
