My NVX died
Hi,
I had a small accident the other day. I shut down the NVX to re-arrange a few things in the room and when I attempted to power it up again I saw some sparks coming out and then the unit died. There was also an associated smell I could sense coming out from the fan grill. I assume some capacitors went belly up. Very sad. I am now looking to replace the unit and I do not know if the disks are alive or not yet. I would prefer to fix the NVX but given the appliance nature and the complexity of the unit this seems not possible at the moment. So I might as well upgrade. I am looking at either a Pro 4 or and Ultra 4 regular or plus. These are x86_64 units unlike the NVX which is 32 bits. Assuming the disks are OK, if I get the PRO or the Ultra and just pop them in, same order as the NVX 1->1, 2->2, 3->3, 4->4, will that work? I also have lots of binaries compiled in it, does the PRO support 32 bit compiled binaries? This is not a requirement, I can always install the libraries or re-compile afterwards.
Also and just in case, is there a way to fix the NVX? I don't think there is any guarantee on it (not to mention that I bought it second hand 3 years ago).
Thank you!

Hmm, maybe that's why the original power supply failed.nbeglitis wrote: I am thinking of cutting an opening where the fan is to let the air flow or somehow disable the fan. The latter is not easy because the power supply cannot be opened easily. It might also not be a good idea in terms of overheating. What do you reckon?
Without knowing how hot your new power supply gets, or what the airflow characteristics are of your NAS, it will be hard to know whether it's safe to disable the fan. But it shouldn't be hard to do; Seasonic power supplies usually CAN be opened easily. What model do you have?
Power supply fans almost always pull air IN, so if you decide to cut an intake vent, keep in mind that the fan won't cool anything unless there's a low-restriction path through the NAS to an exhaust vent.
All of the 4 bay ReadyNAS models have the same configuration i.e. a power supply without a fan.It looks a bit dodgy although I assume the supply failed because of the capacitors. If the fan sucks air in then it is kinda pointless because the exhaust vent in the NAS is probably the space between the disks and the front door. I will probably take the fan out and replace it with a Noctua. Oddly enough, the Kensington lock provides a small opening for sucking air in.nbeglitis wrote: If the fan sucks air in then it is kinda pointless because the exhaust vent in the NAS is probably the space between the disks and the front door.
Maybe. Or the underside of the NAS might be vented.nbeglitis wrote: I will probably take the fan out and replace it with a Noctua.
If your power supply's fan is 40mm diameter, it's probably 20mm thick. Noctua fans are really nice, but as far as I know, they only sell one 40mm fan and it's only 10mm thick... So it will fit, and you'll certainly be able to make it quieter than the current fan, but it might not cool as well. Still, it'll probably cool better than no fan at all.- Removing the fan is not an option because the cable is soldered on the board. Would cutting the cable be a problem? What are the thermal specifications of these PSUs? The original one had exactly that - the fan taken out by NetGear.
- It shouldn't be a problem to cut the cable. For the temperature, I'm not too sure but anything under 80C is what you want, do you have a temperature sensor you can use? It doesn't sound like you have a soldering iron, if you did you could solder a resistor before the fan which would lower the voltage on it - http://www.blackfiveservices.co.uk/fanspeed.shtml
I had the same thing happen to an NVX we had, power supply died. I just plugging in an ATX power supply so I think that may have damaged the board as I didn't see the ReadyNAS PSU Pinout PDF and it wouldn't start (12V and -5V would have been shorting out with the 12V). I removed the -12V and -5V and now it starts but all the lights are on and the LCD shows weirdness as below, has anyone seen this before? (eventually the LCD characters will disappear slowly and re-appear if I unplug and then re-connect the LCD cable)
- I ended up swinging the back plate back and forth until I broke it. The side panels keep the tray in place and the power supply has plenty of openings to breathe!
