Watcooling box Circuit help

[joker_927]

I'm building a seperate water-cooling box for my computer. In it, will be the pump, res, radiator, and all fans. I don't want to have two switches (1 for my computer and one for my pump) I know you have set it up to where you turn of your computer, your pum comes on. I thought I heard someone say you could do this by using a relay switch. I have no idea how though.

I don't want the pump running off the PC PSU, if that is even possible.

Any tutorials or something?

1. Don't go pump -> res ... you have a large body of water in the reservior...that will absolutely KILL water flow. Go with Reservoir -> Pump -> Radiator -> waterblocks -> Reservior

2. http://www.cooltechnica.com/Merchant...ategory_Code=P

take your pick, both will do the job just fine. The pump won't have to RUN from the power supply, it will get it's own power, it just needs to be connected to the power supply to get the signal to turn on.

I hoped I could pick something up from radio shack.
