How are the NB PK-3's working out for you? I've been comtemplating whether I should be going with the PK 2's max @ 1200rpm or the PK 3's max @ 1800rpm. Been curious about noise as well because I want these for silence more than for performance.

I see you've got a SR1 560! - What's it like having the current best performance radiator?
