Hey guys,

I just got my DNS-323 yesterday (C1 now running v1.0805), and something i noticed last night:

After I set it up and then went to bed (all the computers were off) and the drive in the 323 had spun down (i left the default setting of 5 minutes for that), I could hear from my bed in the next room the fan in the 323 start for about 5 minutes on the low speed then stop. It did this consistently every 15-20 minutes or so.

I checked the 323, and the drive definitely wasn't spinning, and it wasn't all that warm either. Am i correct in assuming that if it's sitting there idle, it shouldn't heat up enough for there to be any need for the fan to come on?

It was a pretty warm night last night (prob about 25C), but it wasn't that hot that i'd think that the fans would need to kick in.

I've got the fan set to "Auto:  Off/Low/High" (I had to do the trick previously mentioned here of setting it to "Auto: Low/High" and then changing it back to "Auto:  Off/Low/High" to not have the fan constantly on high).

Also, I did restart the 323 just in case there was a hung process or something like that heating up the unit, but the behaviour of the fan regularly still coming on persisted.

I'm going to check tonight to see if I can see the actual temp of the unit during this behaviour, but I was wanting to see if anyone had any ideas??

Look around, there are a number of people that are experiencing this.  Personally, I haven't seen this behavior, but I'm running plain vanilla, the only "server" function I have configured is FTP.

I'm slightly puzzled here - what seems to be the problem?

You have a NAS with a thermostatically controlled fan that's turning the fan on and off, on what you describe as a "pretty warm night" - that sounds to me like it's doing what it should.

I'm even more puzzled by the fact that you can hear the fan come on at low speed from the next room - you must have either a quiet home or a very loud fan - I can't hear mine running and I'm in the same room!

The problem is that at night when the unit is idle with no drives spinning, and no other services like FTP, or media servers active, the device heats up to a point that it needs active cooling at an ambient environment at 25C.

I find the fan on the low speed quite loud, and has a very noticible 'whine' to it, which I can definitely hear and notice it from the next room in the calmness of the night (we live in a 2 bedroom apartment).

I'm pretty sure that I have gotten it now to a point where at idle it doesn't need to kick in the fan. I've modified the fan control script wiki.dns323.info to work with my C1 hardware version, in order to kick in the 'low' fan speed at a higher temp point (~49C) and stop when the temp goes back down to 45C.

It seems like this is good for my situation in that it very rarely needs to fire up the fan when idle (the temp when idle usually sits around 47-48C without any active cooling), and when it's in use and the fan does come on it usually only takes 1.5 minutes to bring the temp back down, and usually 10-30 minutes for the temps to that point again.
