Thanks for the reply. Yes, I understand the basics of phase change (I think

). I was just wondering if it is accurate enough for people say they have a phase change cooled rig, when it's actually water chilled via phase change.
For now, I am wanting to just water chill, so I can still be able to take my rig on to a LAN. How? Well I needa find some fittings that when they are unplugged, they close, like those on air compressor hosing (no water loss, or very little). This way I can swap my water lines to either my heatercore, or to my chilled reservoir. Which is why I asked if I could use my heatercore to release the heat to the chilled water, or if I need something different. If so, what's going to performe the best? A fairly long strech of copper pipe like the evaporator? Or wha?
