I was thinking about purchasing this kit for my dually 1900 as its currently running too hot for comfort (56C) Do I need a heftier pump (Eheim 1046) than what comes with the kit for cooling 2 cpus? I'm not sure yet if Im gonna get coolers for other components or not yet. Maybe the geforce4 cooler. this rig wont be overclocked as this chipset is a poor OC'er and I am going for stability here, only reason im going with water is its in a poor airflow mid tower now and when im done with my current case project it will be in an even smaller mid tower with uncertain cooling properties and I dont want a lot of holes in the case (will spoil the effect of the mod)
