Found buyers for most of the parts, ordered new ones. Noctua D15 and a half dozen of their silent 1700 rpm fans. I hope to be up and running again shortly.Started off on silent aircooling, while heavily overclocking. Alot can be done with sound deadening, redirecting exhaust sound downward, running on carpet/rug and buying a case that helps with this (ideally steel, no window, no top exhaust ports, front with cover over air intakes - i.e. an old case)
Switched to watercooling. Didn't change my loop for years. It somehow ran fine.
Then I had to change my CPU block and I couldn't be bothered.
Got the itch to switch back to watercooling and had a difficult to fill radiator, bad routing, pumps failing, etc.
Putting up with a little more noise, but happily back on air cooling. Limited benefit to overclocking/watercooling, nowadays.
