Thanks Spyder! After work I'll do some more fine tuning and post some temp comparisons with and without the solid panel. Either way, you can consider this issue resolved :)
🤣
Alright so the details:
Left them all on AUTO mode as the RPMs were being reported, so figured it was working fine already. Stuck them all on 20% where they are still on and doing their jobs but it's low enough that they are barely audible. Incidentally, 20% appears to be where the RPM is...
Tis a mystery!
To be fair I have taken a fair bit of satisfaction in learning how some of this stuff works. I'll probably have a go at a build myself for the next PC.
For now, looks like I have to remove the *expletive* front fans in order to get the cables into the right place...
Anyway...
Yeah that was a dead end. But at least I can now configure my 3 additional non-existent RGB fans.
My first order of business as resident fan expert is to award myself with medal for participation and tell myself to go bleep myself. Politely.
I have to admit I got put off when, trying to add them manually, the software presented me with selection of RGB fan types to choose from, but maybe I should have selected one of them and seen where it would take me. I'll try one more time.

Ugh no dice with the corsair hub. They weren't picked up by the wizard and they are going at the exact same speed as far as I can tell. Doing some googling seems to indicate that 3 pin fans can't be controlled by the hub, presumably for the same reason (lack of PWM)
I set both CPU fans...
@Scott
No effect at all. Fan RPM unchanged after putting in DC mode, reducing to 20% power and saving and exiting and restarting. Back in BIOS again; no change.
Sorry I did actually say that the front fans are connected to the 3 pin headers on the case controller. I've posted a lot and sounds like you are really busy so no worries if you missed that bit.
So where we are is all 3 fans are connected to the nexus hub. The nexus hub is connected via the...
