Have a few questions about new rig

you wont overload the DD5, they can support enough power per channel.

UV dye for glow and some water wetter to make sure the baddies die

Radio Shack sells relays

Hi, I'm getting a new WCing rig for christmas and I have some questions.

I'm going to be using a closed loop system, with 2 120MM fans in a push pull config. with some 80MM fans for hard drive & video cooling.

My first question: Is there anything I can use to monitor temps and adjust fan speed? I thinking about a DD5 or a Vantec Nexus fan controller, but they use 3 pin connectors and I don't want to overload it.

Q #2: What should I put in the water for a cool glow effect and keep nasty living goo out?

Q #3 Where can I find a relay that will turn my pump on when I turn my computer on?

That's all for now.
Thanks
