External Radiator Unit
This has two triple 120MM Danger Den radiators. I am using a HYDOR L35 pump, and a Sunbeam Theta fan controller, but plan on switching to something else, as the Theta software doesn't support XP 64 bit.
If you notice the two relays, one controls the pump when the power supply is turned on.
The other relay is powered by a cable running from the PC.
When I turn on the PC, the power trips the relay, turns on the supply, which in turn turns on the fans and pump.
