[Build Log] 'Set and Forget' ... a NAS in a CaseLabs Nova X2M running FreeNAS - Page 12

Build Adventure ... Further Fiddling #1 - Fun with Fans
____________________________________________________________

The Aerocool Deadly Silent (DS) fan. Ramps up to 1380RPMs (info on the fan claims 1500 ... but ok).

I tested dBs at 1m and 10cm ... 37 and 57 for this fan. Ambient (ie everything off) was 33. I picked up a spare PSU (Corsair CX430) for $25 to test the fans ... you can never have too many PSUs. The fan in the PSU is always on ... even with only pushing 1 fan ... and worse yet ... the Corsair fan ticks. No way am I putting that in a PC.

Anyway, reducing the RPMs 1020 (my standard for sound levels) reduced the dBs to 52 at 10cm.

One of the white fans that came with my 550D ... maxed out at 1260 and 35dB (1m). I didn't do anything else with this.

NAS-0135s.jpg

Another junk white fan from my 550D. 900RPM at 12V, 34 dB.

NAS-0136s.jpg

The NoiseBlocker NB-eLoop (B12-2). Max RPMs is 1300 ... but it maxed out at 1260 for me (close enough). At 1020, it was 34dB (1m) and 40 (10cm).

cpachris (from BBBB and PPPP fame) gets stacks of fans and then cuts their cables to 4" (all the better to sleeve and manage). He will have a difficult time with this NB as the cable doesn't even get close to 2", let alone 4". It does come with two cable extenders (short and long) that have non-covered male 3-pin fan connector.

Noctua NF-S12A FLX (from Amazon via USPS, arrived today). Max RPMs is 1200. At 1020, it was 34dB (1m) and 37 (10cm).

NAS-0138s.jpg

So that is that. The Noctua wins the 'be very quiet' contest. The funny thing is that it doesn't. Regardless of what the dB meter said, the Noctua sounded louder than the NoiseBlocker (NB). I even asked some others and they agreed that the NB is virtually silent ... you simply cannot hear it ... even at max.

I tried to run the dB tests again, but the boiler came on, the dogs started to run around upstairs and someone with heels decided to take a tour of the house. So much for a nice quiet location to run some sound level tests. I'll take some recordings of the DS, NB and Noc tomorrow.

Don't you just love the little wires on the Noctua?

Build Adventure ... Further Fiddling #2 - Recorded Fans
____________________________________________________________

I recorded the NoiseBlocker eloop B12-2 and the Noctua NF-S12A FLX together. During the first test, someone decided that they just had to have a shower ... then the boiler was going again ... and in this test, we just had to turn the dryer on (0:41 or so). This sound recording illustrates the NB v Noctua head to head (for noise).

Build Adventure ... Further Fiddling #3 - Moving Fans
____________________________________________________________

I've swapped out the DS fans at the front for the NB fans. The NB fan that I had in the exhaust slot has been combined with my other NB fan and they are now both up front. The Noctua FLX is currently on exhaust patrol. I've ordered another NB fan that will take over (due Tue).

The noise at full from about a foot away was 44 dBs with the DS fans. With the two NB fans up front and the Noctua in the rear, the noise at full from the same spot is 40 dBs. Quieter ... but lower RPMs. I'll post an update on the temps in a day or two.

Build Adventure ... Spin-Off #3 - Updating FreeNAS
____________________________________________________________

Time to upgrade a FreeNAS system. It is pretty easy ... log into your NAS, sign in as appropriate and then check the 'System / Update' section ...

FreeNAS-0009.jpg

... and then click on the 'Apply Pending Update'... then wait. The first thing that FreeNAS does is create a boot option. Every little bit of O/S gets archived and you can boot back to that version at your leasure.

FreeNAS-0010.jpg

And here is your new boot list with the updated version as the 'active'. You'll need to reboot ... but that is it.

Build Adventure ... Spin-Off #4 - FreeNAS Scripts
____________________________________________________________

One of the items that I spent a fair amount of time on was developing reporting scripts for my FreeNAS system. I lifted tons of very useful scripts from this thread at the FreeNAS forum.

Then I set up some cron jobs ...

Now I get regular emails on a number of things about my system.

I have 6 4TB HDDs in my NAS. The Nova with two HDD cages can hold 8 ... 4 in the top and 4 in the bottom flex-bays.

Pic to remind you :) (Click to show)
NAS-0121s.jpg

I looked at where the 6 drives are in the group and this is the result (coupled with a recent temp report) ...
Code:
ada0 WD-WCC4E6T*****: 26 C   <- bottom cage, far slot - closest to the back plate
ada1 WD-WCC4E6T*****: 28 C   <- bottom cage, one slot over
ada2 WD-WCC4E5R*****: 28 C   <- bottom cage, one slot over (again)
ada3 WD-WCC4E0A*****: 26 C   <- bottom cage, near slot, furthest from the back plate
ada4 WD-WCC4E3X*****: 26 C   <- top cage, far slot - closest to the back plate
ada5 WD-WCC4E2R*****: 26 C   <- top cage, near slot, furthest from the back plate

It is not surprising that the 2 HDDs that are 'sandwiched' between the other drives (ie middle in the pack of four) have the highest temps.

Why don't you do three in the bottom one and three in the top?

Good question. I looked at that ... but I also need air across my passively cooled CPU. I do have two 140s up top blowing air down so that might provide cooling for the CPU. The CPU 'ribs' run horizontally ...

Warning: Spoiler! (Click to show)

... so air in from the front should be better than air from the side.

In the end, I decided that I will just monitor the situation and run the fans enough to keep the temps well below 40°C ... as in 5° or so ... and just stuff junk in my ears if it is too loud.

I'll post some comments on the ones that I used at a later time.

I ordered a bunch of screws and nuts from sleeve-modding for this build. You can see them being used to hold my fan controller in place and to hold some cable management 'clips'. My original order asked for M3 and M4 round heads in lengths of 6mm and 10mm (and enough nuts for same). I also ordered some sleeving (but more on that at a later date).

When the order arrived, I had 3 lots of round heads and 1 lot of countersunk frown.gif screws. I emailed the site and they said 'oops - we'll send you the right ones at our cost'. Well, they arrived yesterday and the package included screw caps ... no cost to me. I'll give them a try.

My other NoiseBlocker arrives today ... it will take the place of the Noctua fan in the exhaust slot at which point I will reduce all fans to about 1000RPMs and monitor the temps for a few days.

This could be the last post about this build for a while. I still need to do some fan cabling and I want to start investigating plex for turning all of my DVDs into on-tap versions ... but more on that later. Time to actually start using the NAS and not tinkering with it. biggrin.gifthumb.gif

Edit: After I do one more temp update from the temp email that is due around midday.
