options for finer control over the fan speed (minimum voltage setting)?

Not something I've ever played with, so you are of course on your own.

That said,

ls -all /etc/sensors.d

will show you what conf file your system is using.

On my RN526 it shows

root@NAS:~# ls -all /etc/sensors.d
total 4
drwxr-xr-x 1 root root   46 Jul 28 07:04 .
drwxr-xr-x 1 root root 2800 Jul 20 09:18 ..
-rw-r--r-- 1 root root    0 Apr 23  2012 .placeholder
lrwxrwxrwx 1 root root   33 Jul 28 07:04 system.conf -> /etc/frontview/sensors/RN526.conf

There should be a fan minimum speed setting in there.
