Hello 'Z440Roger',
I was prompted recently (by forum's admin, automated message) to close this thread, by either accepting the most useful response or post an additional feedback or question. It just so happens that I finally got around to it, to replace the original Adda fans with a pair of new AVC fans I just received in a mail. Before I do this, I've got one more question for you:
How did you rearange the wires on the fan connectors of your Noctua fans, to match the oddball PCB fan header wiring scheme of the HP/Delta PSU ? I can't imagine you just plugged in your Noctua fans and make them work, considering the reversed wiring color scheme of original Adda fans, which I confirmed with my measurements with a multimeter (at least for the GROUND and +12 fan header pins).
Your input would be invaluable …
Kind regards, Sebastian
