Hmm i Am really intrigued here, because both of you are failing to grasp the differences between "real watercooling" as custom watercooling loop, i thought saying pixie dust would have been picked up as a jest ( noun a thing said or done for amusement; a joke.) would have been obvious then explained what the definition of water cooling so it would be picked up that both use pump, copper plate, radiator reservoir with liquid flowing through tubes but apparently this does not make it watercooling? If you have a XPSC stealth radiator a no or small reservoir and a light DC pump, is that proper watercooling? yet performance of it will be about on par with a AIO, so it is true watercooling or not? While I understand your definition of "proper watercooling" as a large custom watercooling setup which has selected parts and constructed together to make a loop with thick radiator and a micro fin stack along with a large resolver for optimal performance which makes it significantly better than a AIO. So if you have a custom loop with a chiller, is it a chiller setup? or proper watercooling?, and if proper water cooing then what of a custom set up that you defined as "proper watercooling" since the definition between the two for you're selves is performance. Yet performance with the chiller setup is far superior to that of a "proper" watercooling set up between parts and whats in the setup. As this specific thread is about PBO which alot of people are confused about and if googling they may end up here and then you use this sort of wrong definition which causes further confusion as to how it works and how to spot it which people new to computers may not understand PDO, AMD did not help specifically clarifying on it either for the technology illiterate, then you come out with "proper watercooling" just confuses people thats not all that clued up and all you are doing is confusing them.
