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

I installed the EnableFanMinRPMOverride add-on and set it to 2100 rpm. After a recalibration the fan speed is around 2200 rpm but it emits a slight clicking hum wich is a bit annoying as I have the NV+ on my desk. The clicking disappears if I set a minimum speed below 2000 rpm (1900-1800 rpm). The temperature didn't fall that much. Just a 0.5 degree lower both on board and on disks (before the fan speed was about 1700-1800 rpm). I have two disk tray still unused as there are only two drives in my unit. Do you think removing them could help psu dissipation? Thank you

I'm not sure where the clicking could come from -- are you able to tell by putting your ear close to the unit? Keep in mind that the fan speed up is meant to increase the ventilation of the PSU head -- not necessarily to reduce the disk and board temp. The board is at the top of the chassis, so the board temp will not reflect the temp of the PSU. And your disk temps are probably running at the low range already.
