Hi All
DNS-327L
Current 1.06 Firmware.
I might be paranoid but the fan on my share centre doesn't appear to be kicking in properly and I wondered if anyone else had this issue or knew if there was a settings file somewhere to change the threshold at which the fan switches between; Off, Low and High?
I was monitoring my Share centre as I was having some OwnCloud issues and I noticed that the system temperature was at 51'C and the fan was still set to Off. I have always had it set to Auto (Off/Low/High). The room temperature is about 17-18'C. The only change I have made is to add a second hard drive in RAID 1 which I understand restricts the airflow but I assumed the auto setting would compensate and just run the fan more.
The system temperature threshold is 61'C. I assume this is a thermal cut off rather than the point the fan kicks in (this is the default value). I would have thought at 51'C that the fan would come on? and this wasn't under any great loading.
Any Ideas?
Thanks in Advance

First, any SATA drive that gets above 50C is heading for trouble.
Does the fan turn on at all, try the 'On' setting. It may be that the fan has a problem starting. There are many things starting from dust to dry bearings that can prevent the fan running.
If the fan runs easily on the 'On' setting (instant start full speed etc.) then you may have to adjust settings.

HI ivan
It does appear to run ok when I set it to Auto (Low/High) at Low it runs at circa 3000RPM and keeps it all happy at 31'C idle and up to 40'C at load. When manually set to high it spins up to circa 3800RPM.
I am quite happy to leave it on Auto (Low/High) and accept i may have to splash out £5 at some point to replace the 40mm fan rather that £100's on new drives etc. It is just strange that it doesn't appear to be able to adjust the fan ratio itself dependant on temperature anymore, considering it used to do it fine.
Would anyone else on here be able to have a look at there temps / fan speed?
There isn't a file somewhere that sets the temperature Vs fan speed that I can get at with Quiexplorer is there?
Cheers

It sounds as if it might be a physical problem rather than a software/firmware problem.
By that I mean the circuit that starts the fan in the 'off,low,high' setting does not appear to be switching when it receives the start signal from the temperature sensor. That part of the circuit is not operational in the 'auto,low,high' setting.
The temperatures you are seeing are good for long life of the drives and, yes, £5 is much better than new drives and unless it is very dusty where your unit is installed you most probably won't need to pay that out for several years (we have a couple of DNS-323 boxes that are set that way and they have been running continuously since we bought them when they were first available, actual date lost in the mist of time).

Hi Ivan
Thanks for the reply again. Good to know that leaving it on Auto (Low/High) has been Ok for you in the long run. Since it is way out of warranty I may open it up to inspect the fan make sure it is chocked with dust, visually it looks ok but there may be something inside.

Noticed, I´ve lost two hdds because high temperatures over the years in my DNS 320 and in my DNS 327L, temps were above 55ºC constantly.
Today I left the top open and with two 120mm fans blowing cold air in my DNS327L (since DNS320 is a piece of crap), also rump up the in built exhaust fan to 4200rpm, now temps stay around 34-38ºC.

Thanks for posting.
Might be helpful to post pictures of your fan mod as well for future users to look at.
Enjoy. ;)

Tks, it is a damn ugly "mod" , but it helps with the temps a lot, I really don't care for the appearance, I just don't wanna see my HDDs dying one after the other due to high temps.

Cool, Does this model DNS have air vents in the bottom?

Yes, it does. ;)

Also, many improvements were made since the old DNS 320, the rear fan is one of them, in dns320 it screams loud, in dns327l it is so quiet and efficient, can´t hear a thing.

Then one possible easier solution for users would be to use a laptop cooler under the DNS unit for easier installation and addition of additional cooling:

I keep something similar under my main host router at all times. ;)

Thanks for the tip, I have one of these lost here in my stuff. :)

Just an update for the fan vs temps:
Using now the NAS as it should be (closed at the top), rear fan at 4000 rpm (silent) and now with an external USB fan blowing air to the bottom of the NAS, results are very good:
Ambient Temperature: about 25-27ºC
HDD1 under load: 35ºC
HDD2 under load: 34ºC
System temp under load: 35ºC
:D

So now just using a fan on the side huh? :o

Yep, targeting the bottom of the 327L :)

My DNS-327L with 2x4TB WD Red keeps between 48-51°C. Could you please point out how you managed to "rump up" the fan speed?

Hi,
It's in Portuguese, but you can have an idea where to set it up.

Hi,
Thank you for the reply. I do understand now! You set the fan on manual. I though there would be some clever way to edit a config file or some thing like that.

Hope this works for you. Should you need additional cooling, I recommend getting a USB powered laptop cooler fan and place the DNS on top of this cooler.
Works for other heat generating devices like routers as well.
