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

I'm sure the clicking comes from the fan.

If I lower it's speed below 2000 rpm it disappears. And the sound comes clearly from there.

That's the reason why I'm not very happy with this solution to the psu problem.
Not only I have a noisier unit, but I also have this annoying clicking.

And reading other users reports I don't think reversing the fan will help that much. Raising disk temperature and removing dust protection could help psu, but will lower disk reliability.

I think perople from Infrant should think about offering us a more reliable psu as a retrofit kit.

I'd like people form Infrant tech to suggest some fan models (if there is any) that could lower the noise without lowering the cfm.

It is easy to change the fan and I would be happy to spend a few bucks to get a more silent unit even with a fan running at 2100 rpm.

But I don't fell like choosing only reading the tech specification of fans.

Guys, there's a simple $2.99 compressed air solution to any dust build-up problem if you go for the quieter fan reversal procedure. It doesn't hurt to shoot a couple puffs in once in awhile, and you would need to do this without fan reversal anyway (the black mesh in the front will filter the dust but you'll need to clear it once in awhile).

Okayy... I did the "fan swap side trick" yesterday. My NV SN is right in the middle of the batch. I cleaned the whole box at the same time. But bad news today : the temp is UP (and the weather cooler than yesterday...)

Disk 1 WDC WD5000KS-00MNB0 465 GB, 51C / 123F, Write-cache ON, SMART+ OK
Disk 2 WDC WD5000KS-00MNB0 465 GB, 53C / 127F, Write-cache ON, SMART+ OK
Disk 3 WDC WD5000KS-00MNB0 465 GB, 54C / 129F, Write-cache ON, SMART+ OK
Disk 4 WDC WD5000KS-00MNB0 465 GB, 51C / 123F, Write-cache ON, SMART+ OK

Fan 1 2205 RPM
Temp 1 44.0C / 111F

I even installed the add-on to speed up the fan. No luck. Drive 3 even reached 60°C some hours ago. The hot air is now trying to escape from the front. I'm thinking of changing that back... Any other idea ? :/ (ho, and even with all services disabled, the spindown feature is useless : all the drives are spinning back up right away... :( )

See if opening the door reduces the drive temp. If so, consider removing the black mesh as that's what keeping the air from ventilating out faster.

Opening the door does help a bit, but the NAS is still 3 to 5° above what I had with lower fan speed, when the fan was in the "wrong" position. Weird. :(

I would expect the temperature to register a bit warmer. In the original configuration you are pulling "fresh" air from the front, over the drives, board, and PSU and pushing out the "hot" air through the back. The new configuration is to pull the "fresh" air over the PSU, board, then the drives. The drives are getting air that is warmed by the PSU and board. The drives are still running within acceptable temperature.

With drive 3 trying to break its 60° C record, I find that a bit too high... :/

I have now tried two of the options offered: reversing fan/leaving door open and applying the min fan speed plugin.

The first option of reversing the fan worked fine but the door had to be open otherwise the HD temperature went to 55c +. I pressed out the metal grill on the door and removed the filter (easing the edges inwards befoire replacing the grill to allow future ready access). This brought the temperature right down but I have worries over potential dust ngress problems.

I then tried restoring the fan to normal and washing the filter in warm water The temperature is now 29.5c with the disks running between 35c and 39c. I then applied the min fan plugin for security.

The second option is by far the best. Noise is not substantially increased and the system has a modicum of dust protection. For me the biggest single factor in improving cooling was the washing of the filter - it needs to be done once a month at least. By making the grill easy to remove the filter cleaning is simple.

Maybe Infrant should a) make the grill easy to remove and b) make the cleaning of the filter mandatory, possibly popping up a reminder every 30 days?

One easy way is to use a compressed air can to blow the dust out or to use a vaccuum to pick up the dust build-up. As mentioned in another thread, you'll see a crop-circle image when dust has built-up on the vent.
