Undervolt cold cathodes?

post #1 of 7

http://www.newegg.com/Product/Produc...82E16811994001

Bought thee a few days ago, and installed them 5 minutes ago. I love them they do everything i expected and have a very clean look. But my ONLY complaint is that they are very bright, bright to the point that they look almost white. Is there any way to undervolt these lik i did with my fans? They use some weird 3 pin system that goes into this weird converter box.

I believe if you cut the wires and lengthen them they get start to dim.

I have the same ones (never modded or did anything to them) but I have never had a problem they look blue to me.

If you hook them up to a fan controller they will dim, but too little voltage and the light will only "extend" so far. Starting at one end and ending like half-way depending on the voltage.

If you have a 7v molex to 3-pin adapter that might work as well.

I used to use 2 6"cathodes by the same company. Only fix I ever tried was making a reflector for the cathode to keep all the light going to my components.

Now I use blinky LED sticks...less bright and cycling flashing patterns make the case more interesting...and they run colder.

The best way to undervolt them is with a fan controller. The box/white wires are high voltage (>600V), so its not recommended to modify them, only modify the black/yellow/red wires that go from molex connector to the box.

If you treat everything after that box like you would a fan, you can undervolt them exactly as if they were a fan. As other people have mentioned, they may not fully light up if the voltage is too low.
