I think I know what your talking about. It's related to Unicode. Unfortunately I haven't really dealt with this problem in years (say 2002-2004). I can't recall how to fix it or how I got around it...
Liquid is normally better than air cooling. Much better. Think of it this way, what's going to cool a hot pan down faster, leaving it by an open window or just dropping it into a tub of water?
But like any kind of liquid piping, you have to be sure your setup doesn't leak and maintain it. Also, you normally don't use regular tap water. You use a distilled or deionized water or some non-conductive liquid in the case that it does leak and make your new system into a giant paperweight.
RAM can be a little fussy, especially if the voltage is higher than what your motherboard will run. The more expensive stuff may not run right out of the box as the cheaper stuff and may require some tweaking. But the more expensive stuff is usually geared toward gaming machines anyways.
