OS 6.5.2 still causes fan issues on the PRO 6, like OS 6.5.1 but unlike OS 6.5.0

You could try

# echo 1000 > /etc/frontview/min_fan_speed_override
# systemctl restart readynasd

as a temporary workaround. This forces the NAS to aim for a higher minimum fan speed of 1000 RPM which may be necessary for some fans.

This is a change you can easily reverse by removing the override file and restarting readynasd.

Edit: Now that 6.6.0 is available you may wish to try that.

Went back to OS 6.5.0 and it seems the quiet setting on 6.5.0 does not go under 907 RPM, where as 6.5.2 slows down to 555 RPM which creates the warning.

I think a possible fix was committed to the 6.6.0 branch but not to 6.5.2.

Thanks.

I'm a bit reluctant to verify this as I understand I cannot go back to 6.5.0 once upgraded to 6.6.0. And as I shared in another thread, the PRO 6 fans work absolutely GREAT on 6.5.0.
