It's possible that editing the sensor configuration with ssh might fix it. But I haven't had to do that, so I'm not sure exactly what change would be needed.
You might want to compare /etc/frontview/sensors/ULTRA6.conf with /etc/sensors.d/system.conf. I believe they should be the same. This would require ssh access.
I have recently updated frm OS4 to OS6 on my ReadyNAS Ultra 6 Plus (with upgraded processor and new fans too). Although I am not facing the same situation I noticed that after upgrading sensors configuration for my NAS are as follows:
/etc/sensors.d/system.conf is a symbolic link to /etc/frontview/sensors/NV6.conf
With this configuration my NAS is indeed showing up two fans (System and CPU) and two temps. Fans seem to be fairly well behaving... however, they do not seem to respond to changing the cooling profile from (Quiet to Cool or Balanced)... at least not on the graph where speed do change but seems to be unrelated to whatever is being shown.
I tried to fix it by changing the symbolic link to point to ULTRA6.conf under /etc/frontview/sensors but after rebooting the NAS I experienced something similar to your situation where the Sytem FAN seems to stop (and it seems sometimes it actually does as no air seems to flow from the rear). With it pointing to NV6.conf seems to recognize both fans and keep them spinning... although I do not seem to get accurate control of their speed.

If the temps are already low, then changing the profile might not matter.
Did you try putting the NAS under some load? Doing a scrub would do it (though one disadvantage is that you can't cancel it). You could also try a very long transfer test with NASTester. http://www.808.dk/?code-csharp-nas-performance Then see if the various profiles make any difference.
Well my NAS has been resynching discs for the last couple of days. It is currently CPU at 49° C @ 1406 RPM and System at 63° C @ 2109 RPM. What makes me think something is off is the fact that CPU fan is a Thermaltake fan 80x80x15 mm rated from 1200 to 2400 RPM. I have never seen the CPU fan go over 1500 RPM though.
Disk temps seem to be similar to what I used to have in OS4 (for the WD RED NAS drives betwee 44° C and fior the HGST drives a bit over 46-48°C . Right now since I upgraded to OS6 I have been adding drives one at a time to the array so NAS has been stressed for over 5 days rebuilding the array and expanding . So I would think this might be "normal".
Although I cannot recall fan speeds when OS4 was installed, I do remember the fans seemed to be louder, specially while booting up the NAS. Today. although I have set the profile to cool (to kind of forcing the fans to max throughput), they seem to be quiter that they used to be.
NV6.conf is the correct configuration for an Ultra6 Plus. It has the same motherboard as the Pro6. which apparently was orignally going to be called the NV6. The Ultra6 (non-plus) is an entirely different archetecture. On my Pro6, there is a system.conf and a pro6-fan.conf. pro6.fan.conf contains the following:
chip "w83627dhg-*"
ignore fan3
I'm not exactly sure how that could make the difference, but you could give it a shot.
It has been stable for the most part... I did some modifications to the NV6.conf file such as stablishing min and max speeds for the fans.. however I have not noticed any change in behavior of the fans so far. Still getting arounf 1,400 RPM for the CPU fan and 2100 RPM for the System fan. Oddly enough.. the System fan which is a Noctua Noctua NF-F12 iPPC-2000 (rated from 450 to 2000 RPM)... so not sure why it is showing up 2100 (probably just because of the error margin in the fan).
Anyways, I have just bought a Noctua NF-F12 iPPC 3000 PWM rated at 3000 RPM max... and will test with it. Only caveat this is a 4 pin PWM fan but I think it should also work from the 3 pin header in the system board. Anyways.. I am just waiting for a memory upgrade to come in to open the NAS again and do some testing with this fan.
Today I decided to replace the 80x80x15mm fan on top of the CPU heatsink with a Sanyo Denki 9GA0812P7G001.This is a 6100 rpm rated fan that is supposed to provide 50.9 CFM.
However upon restart of the NAS I noticed the system performance tab would show the fan spinning at a maximum of 2445 rpm even when set to the Cool profile.
What adjustments would I need to do to the NV6.conf file so the fan actually performs as per its specs?
I modified NV6.conf and changed "set fan2_max 6100" in it. However, upon another restart from the NAS I am noticing that the fan now reports to be spinning at about 1800 RPM (even less than with the original value of 2400 I had there.
ls -all /etc/sensors.d will show you which .conf file is in use on your system,. It will be ULTRA6.conf for an Ultra 6 (non-plus) or NV6.conf for an Ultra6Plus.
ls -all /etc/sensors.d will show you which .conf file is in use on your system,. It will be ULTRA6.conf for an Ultra 6 (non-plus) or NV6.conf for an Ultra6Plus.
Thanks for your feedback... the system is using the NV6.conf file and that's where I have done the adjustments to the fan2 config:
label fan2 "CPU"
set fan2_min 1200
set fan2_max 6100
However, with this configuration the fan rarely goes beyond 1,800 rpm @ a CPU temp of 51 °C

Is your CPU fan plugged into the 4-pin header near the CPU or the 3-pin one on the I/O board? Is there any .conf file in /etc/sensors.d other than system.conf, which points to NV6.conf? If so, what does it contain?
My Pro6's NV6.conf file has no fan max entries. Maybe adding them in is creating a problem?

You may notice I was tinkering with the temps on the CPU since the Xeon processor is a 4 core CPU that is properly recognized by the NAS. However I have not yet been able to identify what other "temps" are valid and decided to simply keep the file as it was originally, ignoring all other temps but the temp2 which is referred as CPU in the original NV6.conf file.
That looks like what I have, except for the max speeds on the fans. Mine has none. My CPU fan is connected to the 4-pin header near the CPU. I know some Pro models were shipped with a three-pin fan plugged into the I/O board, which I assume is one of the ignored fans. I don't know if any Ultra6Plus's were shipped with the 3-pin fan.

My Ultra 6 Plus has a CPU Fan contolled by PWM by means of a 4 pin header next to the CPU in the NAS MB. There are two 3 pin headers in the daughter board that has the Ethernet connections on it but it is the 3-pin system fan which is connected to it. The other heather in that board is not used.
I downloaded the logs from the NAS to try to figure out how to adjust the fan max speeds to allow for better cooling. looking at the boot_info.log file I noticed the "type" for the fans are set to 1500...
