I have a water cooling system that i am going to put into my computer and i have 2 questions about it: First, is it better to put the radiator in the bottom front of my case and have the fan blow air through the radiator and into the case, or is it better to have the radiator at the top back of the case and have the air from the case being sucked out through the radiator. I also need to get a peltier that can cool a 1Ghz Tbird and run on its own 250W or 300W power supply, does anyone know of a good cheap pelt that can do this? Any info would be appreciated.
