the only closeness in performance but quieter were the Noctua NF-F12 fans. higher
price, but kept to 2°-3° to the OE H100 fans in a dual set. didnt try p/p.
i tried bitfenix, artic, cougars, GTs, swiftech and all had some idiocracy. i doubled
back and used SP120 undervolted 7volts and enjoyed them greatly.
