Like many other users of the DNS-320 i have problems with the fan and fan settings.
I use the newest firmware and the fan is running and running. I don't understand it.
Why is it so difficult to code a firmware which tells the fan to stop when discs are in hibernate?
Every device in my house is stopping fans when going to hibernate.....
There must be something totally wrong with the fan-control, cause the fan runs on low when discs are in hibernate, and it runs on low when i copy files to the nas, so i guess it is not to hot in the nas.....
Can someone from DLINK explain me the idea behind this implementation of fan-control?
This really drives me made cause the nas is in my living room and is running and running.......

I know it's not exactly what you asked (as in an explanation on why the fan-controller works as it does), but in the Fan won't stop - What is a normal system temp? (http://forums.dlink.com/index.php?topic=45170.msg164451#msg164451) thread i gave my solution to the noisy fan problem, here's the quote :
I "fixed" the problem of the noisy fan by taking off the top of the unit and putting there an 80mm silent (Noctua) fan connected to the USB port of the NAS. The fan blows air downwards over the HDDs. Now the unit always reports as being around 40 centigrades (103 Fahrenheit) and the HDDs report as having 27 centigrades (80 Fahrenheit).
Because of this, the internal fan is OFF all the time.
I know it's not the most elegant solution, but it works great. Now, all i have to find out is how to put a filter between the fan and the unit so it won't get filled with dust.
P.S. the fan just "sits" on top of the HDDs for now, I'll have to see if i can make a support for it. I don't exactly want to modify the top of the unit as i would have to drill a big hole in it for the air to enter

No i don't think that this will solve the problem at all.
For example, the NAS was the last 2 days not in use, the case is opened already and the room temperature is about 22°, so the temperature near and inside the NAS can not be that much higher at the moment, but fan is running.
I don't know to which temperatur an external fan should cool this down to stop internal fan at all......
I found something interessting in the Recent Activities list:
It says that today at 10.49 the fan-control was set to Auto(Low/High), i think the NAS is doing this on his own, cause at this time I wasn't at home at all........how can that be?
-
What do you have the fan set at on the 'Management' -> 'System Management' -> 'Power Management' -> 'Fan Control Settings'?
To have the fan shut down you need that setting to be 'Auto(Off / Low / High)', anything else will have the fan running all the time. If you change the setting don't forget to 'Save Settings'.
It might also be advisable to check the 'System Temperature Threshold' under 'System Settings'.

I set it to OFF/LOW/HIGH, but it seems that the NAS automatically changes to LOW/HIGH various times.....
System Temperatur Threshold is for complete shutdown, not for hibernate/fan.....
-
Do you ever see 'Set fan speed to 'Stop'' in the Recent Activities panel?
Our units usually show just 'Low' and 'Stop'. In fact we seldom see a 'High' and that is usually during the full backup of the servers.
One other thing I should mention, we are running firmware v 2.0.
-
Is use 2.02. The "stop" command in Recent Activities I only see directly after changing fan mode to OFF/LOW/HIGH, but within 5min later it is changing to LOW.....
A good example is the Recent Activities list from yesterday evening:
Sep 5 21:58:30 Set Fan Speed To "Low".
Sep 5 21:53:11 Set Fan Speed To "Stop".
Sep 5 21:53:10 Set Fan-Control Mode To "Auto(Low/High)".
Sep 5 21:52:04 CIFS: [192.168.178.29] connected to [Volume_1] as user [nobody].
Sep 5 21:52:04 CIFS: Authentication for user [Thomas] has FAILED.
Sep 5 21:49:30 CIFS: [192.168.178.29] closed the connection to service [Volume_1].
Sep 5 21:38:31 CIFS: [192.168.178.29] connected to [Volume_1] as user [nobody].
Sep 5 21:38:31 CIFS: Authentication for user [Thomas] has FAILED.
Sep 5 13:05:40 Set Fan Speed To "Low".
As u can see, there is no "Admin logged in", but the NAS changes FAN-Control mode to Auto(Low/High) on its own.....why?IS the NAS the ADMIN or am I?
Another thing is, i haven't ever seen any command like "send HDD to hibernate", I don't know if this event throws an log?

You won't see much more than log-in and fan speed messages in the log of this device!

Ok thx for this information.
I observed the Recent Activities list for some days now and I have an idea what is going wrong in the firmware. The order of the always the same:
1.Fan is set to STOP after loggin in
2.Within 5-10min of running HDDs it is changed to LOW
3. Fan is running on LOW till someone is accessing the HDD, then the fan is set to STOP
4.Within 5-10min of running HDDs it is changed to LOW
5. Fan is running on LOW till someone is accessing the HDD, then the fan is set to STOP
=> here starts the endless loop.
I guess the firmware is not checking the temperature when the HDDs have gone to hibernate, so fan is running in LOW till someone accessing the NAS.......
I use other NAS systems and non of them has such problems with the fan, I don't understand that this is not improved by DLINK......

It goes from Stop to Low definitely not in 5-10 mins as you stated....do u see the same occuring in my logs?
My hibernate setting is set to the default 1 hour.
-
I don't see the same thing in your log.
But I will change the hibernate sleep time to 1h and check whats happening.
-
fyi im running on 2.02 same as urs, thought mine was upgraded from 2.00
-
Tested several things without positiv result:
-Changed hibernate time to 30min and 1h, without changes
-Downgraded from 2.03 to 2.02 without changes
Logs are always the same, if the fan changes one time from STOP to LOW it stays there, till I access the NAS or Login.
I saw that under Device Information the System Temp is 111F/44°, which can not be true, case is opened and environment is about 21°, and the NAS was not in use the whole night.
-
Hmmm...well my HDD temp is at 0C/34F...the readings are definitely wrong but could well contribute to the fan speed able to change to stop.
sorry cant help u much there...
-
Tonight at 1:30 I had to shut down the NAS completely cause fan was running on HIGH(at 44°), the noise was so loud we can listen to it in the sleeping room......
This morning I restarted it and it showed me a temperature of about 46°, but the fan is in stop mode.
How can that be? Tonight it was 2° cooler and running nonstop on high?And now it is OFF?But for how long....
I can't believe that I'm the only one which is f***ed off with this problem, as many of this problems can be found in the internet.
-
There is nothing much one can do regarding the fan noise, but if the fan is running non-stop even when there is no disk activity then something is wrong with the NAS.
TS, what are the applications/services that you have enabled?
-
I have nothing of the applications enabled, I just use the NAS as network-drive on 2 Windows7 PCs.
-
Does the fan shut off if the NAS is unplugged from the network? The fan on my DNS-320 never shuts off either, unless I unplug it from the router. I have no services running on it, like Media Server or FTP, so I'm stumped.
-
does anyone know if the new firmware 2.03 fixes this stupid issue with the fan?

The change log for this latest firmware version does not mention any changes to the fan control.

Not driven crazy anymore...

The new Fan is this one:

independent with which speed the Fan is running (low or high) you wont hear something.
-
Looking at the fact you are running your NAS in, what is effectively, a box, I wonder if the noise you were hearing was caused by the small fan running at the resonant frequency of that box.
I have two DNS-320s, a DNS-323 and a DNS-345 sitting about 2.5m from me and I hear the noise of the disks starting up but not the fans. Yes, I know there can be bad fans that are almost out of tolerance that will produce noise but none of our D-Link NAS create enough noise for anyone to notice, in fact there have been some people that have had to check that they were in fact powered up.
-
I bought this on Nov. 2011. I gave up completely just two month after and I don't use this anymore.
The fan was never stop. NEVER. I used just one HDD in it and my home was not warm.
Something is wrong veryvery wrong.
Maybe the temp. sensor or fan control code is failed? I don't know.
Anyway I strongly recommend you DO NOT BUY THIS.
-
I did the same.
Bought a Bequiet fan (that works from 4v) from Amazon (http://www.amazon.co.uk/gp/product/B003 … 04_s01_i00), opened a whole in the back (of the black plastic box of the DNS-320) and put the fan there.
It works in Auto-Mode (Stop/Low/High) like a charm. In High mode I cannot hear it and I am getting 34 C° on the HDD and 42 C° on the chipset.
And NO noise finally!! I can't believe I took about one year to decide to do this..

I found s_vad's new post in that thread.
You can switch the fun power supply from 5V to 12V by resoldering the inductor from position L1 to L2 as shown on the pic. But I don't know exactly how much power will it supply in this mode.

I just tried it.
ADDA 80x80x10mm Coolertec 70x70x10mm 12v 0.05A fan works!

Thank for the information Oops, filed and passed on to my service department. It should mean that in the event we have to replace a fan we can use a standard 12v one rather than a very hard to find 5v unit.

2 Methods I've used.
Method 1
**************
My DNS 320 with simply an Acutake ACU-FAN120
sitting on top of an open box has now been running for
over 700 days continious. Its loaded with 2 WD Blues.
The ACU-FAN120 is silient except at start up, and runs
constantly.
Email is set to send me a notification if the box overheats
so far no overheating after about 2 years of constant running.
Method 2
*******************************************************
I've another DNS 320 with a
Arctic F9 Pro PWM fan running it on it.
This Fan changes speeds and does not run constant,
it has a full off/lo/high setting and works with all
of them.
On this machine I've taken off the plastic cover.
I placed 4 rubber feet on the bottom, so it sits
about .5 inches from the surface it sits on.
With 18-36 CFM the Artic F9 pushes 3-6 times more air than
the original. I've also taken the original fan off
of the back so there is more airflow.
The F9 Arctic Fan sits perfectly across the 2 WD Red drives.
I've used some rubber material with adhesive to make a footing
for the fan so it sits perfectly in place and would slide off.

With the plastic case off the unit runs cooler anyways,
as the sheet metal works more effectively as a heat sink.
Without cover the DNS 320 will only work safely
if one has a secure shelf or cabinet to set the unit.
Here are some illustrations.

Rubber feet placed on bottom of unit, these provide further isolation from sound,
as well as provide an airspace so bottom metal panel can better perform as heat sink.

The DNS 320 is a robust, well priced unit. With a little work the fan and ventilation can be made
quieter and more efficient.
