Hi,

I've bought a new fan (NB-BlackSilentFan XM-1) and after installing it, the system can't start the fan. The log says: Fan Is Unable To Spin Or Fan Doesn't Exist

Here are the specs of the new fan:

Code: [Select]

Size: 40x40x10 mm
Rated voltage: 12v
Voltage range: 8,5v-13,8v
Input power: 0,36W

Considering the specs of the original fan (AVC DS04010B12U):

Code: [Select]

Size: 40x40x10 mm
Rated voltage: 12v
Voltage range: ???
Input power: ???

I think the new fan should work. I already tested the fan on a computer and it worked normally, so the fan is not defective.

Does anyone know if this fan, or a fan with these specs, works on DNS-320L?

I had the same problem when i changed my fan to a Noctua NF-A4x10 FLX. The problem turned out to be that the polarity is switched on the connector used for the fan. The solution was to cut the plug of the new fan and switch the negative and positive wires around.

I hope that helps.

That worked! Thanks a lot 

I wonder who had the idea to made the system with polarity inverted. AVC who made the fan or D-Link who built the board. AFAIK, all the fans in the market are exactly the opposite. Well, at least they are not using 5v fans anymore. It would be a nightmare to find a fan for replacement.

thanks!

have you seen any improve with this fan? i am about to buy a new one because i can't stand the noise of the stock one!!

[tsomby]

After replacing my fan, i have System Temperature 116°F/47°C and Disk Temperature 120°F/49°C. Is that ok or it is to high? I have set the fan control to Auto (Low/High).

By chance, I also bought the NB-BlackSilentFan XM-2 from Amazon. Of course, ended up paying twice the price as it had to be shipped to Singapore. Also, not sure the differences between the XM-2 vs XM-1. Anyway, here's what I did. The plastic connector block has 3 small holes on side. Gently tug the wires, then with a sharp tool (paper clip or toothpick), press one by one, the 3 metal connectors thru these holes. It should allow you to pull loose the three wires, white, red, and black.

Now you can match the three wires order with the original fan, which is white, black, red, then insert the metal connectors back into the plastic block. Remove the original fan, replace it with the XM-2 fan, connect, and you should now have a very silent NAS box. It really is quite impressive the change in noise level.

How are people finding the new fan, still generally happy?

I've had enough with the standard one as the noise levels are unacceptable being just as bad as my old DNS-320.

[pizzaking]

Defiantly! I sleep in the room where my NAS is placed, so the noise level were simply unacceptable. The replacement fan is great. I barely hear it, unless it is on high, but even then it's still very acceptable.

Good to hear

Is this the right one to order - http://www.amazon.co.uk/NoiseBlocker-Case-Fan-NB-BlackSilentFan-Version/dp/B002DG1QUM ?

If it helps, my model is the NB-BlackSilentFan XM-2 40x40x10
The specs differs slightly, it's 14 dBA, 4 CFM, it spins faster, 3,800 rpm vs XM-1's 2,800 rpm, it will fit on the box with no problem whatsoever. Well, just that you need to switch the wires to make it work.
Other than that, it's a real charm in eliminating the stock box noise.

Hi...

the fan is annoying me very much too... so does chaging the fan is really effective ?
And is the box still cooled down enough ?

Hi, I've recently discovered that the fan control stops working after some time, so it stays always on.
If you restart the fan_control, it detects correctly fan and temperature, and stops it, so I've added a cron job to restart it every 10min, and the fan turns on rarely since then.
You can check if this is the case if you see "Fan not detected.."in the error log.

Hi,

so i've replaced the FAN. About the noise it is awesome... but i'm not sure the auto mode is working properly...
If i put low/high, the fan is spinning... if i set auto mode, i see it always off... despite the t° is going up (i'm with 48-50°C on the system temp and around 45-50° on the hard drives)...

What are your t° ?

Same here. I have set it to low/high since i replace the fan.
