Basically I'm planning on replacing the inadequate fans (sub 1mmH2O) on my radiator with something that can pull at least 6mm of water/~60Pa. One of the lower end ones I'm looking at getting is a 120mm fan that pulls 8.5mm/~84Pa, while I have a spare 120mm from some other equipment that pulls about 345Pa which I tend to think is too much... the question is, though, exactly how much is too much? The problem is that I haven't really found much info if any on the actual structural/mechanical limitations of consumer CPU radiators. My (probably irrational) worry is that if it ever became clogged for any reason the pressure might damage the fins, which I don't think is likely to happen since even 345Pa is really not a huge amount of pressure compared to like the 20kPa of a vacuum cleaner, but then again without knowing the specs or without setting aside an hour to (handwavily) calculate/guess it I have no idea.
Like I said though, it's probably irrational, but the idea of water spraying around in a computer case is not reassuring me. I mean, I would figure, seeing that the 8.5mmH2O fan and others are only $10-20, that manufacturers would use them instead of the wimpy 1-4mmH2O fans that they install on them, which just furthers my worries.
