That would explain it.

I think I figured this one myself.

I had fancontrol installed from early versions where 6 OS did not support legacy fan control. And it worked really well for me since I had NAS running in my living room and needed it to be quiet. Now I removed fancontrol package and speed jumped to 1700 which is fine since it's hidden away somewhere.

  I think I may be experiencing the same (or similar) issue that you had here, only mine was delayed until I upgrade to OS6 version 6.4. If you have time, would you mind checking out my post found here https://community.netgear.com/t5/Using-your-ReadyNAS/Fan-CPU-in-enclosure-Internal-speed-is-below-threshold-after-FW/td-p/990867 and tell me what you think? If you concur, would you mind elaborating on the proper method of removing the fancontrol package as you did?
  
  Thanks in advance!

    Same issue here, upgraded Pro 6 to FW 6.4 and now the system fan is not spinning unless the system temps gets over 70C. I have tried creating the file and restarting the system and it doesn't do anything that I can tell

fwiw, reboot did not help.

ok, so perhaps a reboot is in order?

or, perhaps, I need to set specific permissions for the file?

is the name exactly correct?

The file doesn't normally exist. It's an override (e.g., if the system sees it, it is supposed to use it instead of the hard-wired minimum).

Yep, still getting them every night as the temperature drops and the fan slows down.

Perhaps the location is different in my system? As I've mentioned the file did not exist?

It could take some minutes for the change to take effect. So you still keep on getting these alerts regularly?

Any other options? :(

Yes. Did not try restarting whole NAS though.

You did the restart part of the procedure?
