Links to instructions for installing TrueNAS with front panel display capability on some ReadyNAS
For those looking to install an alternate OS on their RN42x, 52x, or 62x unit, here is a link to some very good instructions on installing TrueNAS Scale: https://www.reddit.com/r/truenas/comments/1o...

Isn’t another way to do similar :-
DEVPATH=hwmon4=devices/platform/w83627ehf

Close, but DEVPATH doesn't quite fix it. It doesn't follow the device to its new number, it just lets fancontrol notice the number changed. On a boot where the chip comes up as hwmon3 instead of hwmon4, fancontrol refuses to start with "Configuration appears to be outdated, please run pwmconfig again". So you swap a wrong fan mapping for no fan control at all, which is safer but the same annoyance.
If you want to stay with fancontrol, the version that survives reboots is to drop the DEVPATH and DEVNAME lines and point everything at the full /sys/devices/platform/... path instead of hwmonN. That path doesn't change between boots, so it gets you the same result as looking the device up by name.

Cheers, really appreciate the insight. Will add to the list to muck about with....

For anyone wanting a Pro6 fan control profile, you could start with:-
