Unless you spend a significant amount on the water setup, the cooling isn't going to be much better than good air. Especially these days when all the air coolers are very good. However if you do spend the cash on decent water its temps can be significantly better. Then again I'm sure if you spent the same amount on air cooling you might be able to come up with some crazy solution that would be better![]()
