This one is a pretty though one....because while the XP-90C is very good, you do need the fast tornado on it. And yes, you should be able to put the tonado on the fan only line, but bfore you do, check how many watts the fan-only line can deliver so that you don't limit the tornado. But if it does have enough then your psu will quite down the tonado when needed, and when on about 50% speed it still moves a lot of air and is MUCH quieter.
The Thermaltake igwater, well, most people don't like it because it is kind of a peice of crap. I mean, it's not horrible, but at least I would not get it for your 630, as the Bigwater can't hold that much heat and dissipate it.
I know these suggestions were not one of your options, but I would recommend at least getting a swiftech water kit if you want water, or getting a thermaltake Big Typhoon for air cooling. The typhoon is big, but it's also VERY quiet with the stock fan, while giving great temps. Later on you can also change the fan for something with a little more cfm.
But anyways, if you HAVE to go with either the XP90c or the Bigwater, I would take the XP90c.....because it takes up a LOT less room then the bigwater, while temps would probably be almost the same (+/- 3*c)
