OK, I was going to wait and let somebody who knows a lot more than me handle this, but you use the word 'scary' and I'm there with my two cents. There's nothing scary about WC'ing, it's a completely self-contained unit, they're totally reliable and they do a far better job than air. You'll sleep better knowing that once you've overclocked the processor to within an inch of its life, which is after all where all the fun is, lol, you weren't stopped by inefficient cooling which is what air is.
Worry no more, Sun, you're way better off with it and it's totally reliable.
