Service Action to Prevent PSU Failures in ReadyNAS NV/NV+

My NV is outside the affected serial numbers - my serial is lower than the lowest affected serial number. Still, as I had swapped my PSU for a fanless job I decided to reverse the main fan and saw my temps increase by 4-5 degrees. Not good. I've now reverted back to "s.uck" mode and temps have reduced to normal with the main fan spinning between 2100 and 2200 rpm. I installed the RPM override addon as the Enhance_NV_Thermal_Characteristics addon didn't work, and set a minimum rpm of 2300 and rebooted (twice) however the fan is now spinning at 2205 rpm and not 2300 rpm. I've recalibrated several times and it makes no difference. As a test I set the minimum rpm to 2500 and the fan speed briefly changed to 2142 rpm before stabilising at 2205 rpm again. Confused - does this addon actually work?

Your rev A NV won't take the add-on. Instead you can use the EnableFanMinRPMOverride add-on from the Wiki Add-on page. This will allow you to specify the min RPM in the Power Management tab.

Check the bottom of your NV to make sure there's no blockage of the air holes.
