Hi Sprober!

I love your NA611TB3 review! I am also a proud owner of the device - but came to the conclusion that I can't work with this kind of high-pitched noise from its fan... Do you have the same issue? You wrote:

a small fan and a switch to turn off the fan if unneeded on the rear plate

but it seems that the switch is just for two different fan modes: a) high-pitched-super-annoying or b) way-too-loud 😉

Do you have any idea how to fix this? Do we actually need the fan?

Cheers;
J0n

@J0n- I do not have the problem you are describing, the fan in mine is whisper quiet. You are correct the switch on the back is for low and high demand mode, when I first did the review I just assumed the switch was on/off when glancing at it before reading anything and since the temperature blanket was included. A couple of options for a fix off the top of my head:

1. Contact Netstor about a replacement, they have been responsive to my inquiries and seem like a company that wants to deliver a quality product.
2. Replace the fan yourself. Shouldn't be to hard to find a quality fan with the same specs.
3. Open the enclosure and unplug the fan and get a program like DriveDX that monitors temperature and see if you are within specs with just the thermal blanket.

Option three would obviously be the quickest work around but I have not done any temperature tests on mine since it seems to be fine noise wise for me, as my primary use is audio recording noise is a concern for me. Hope this helps some.

WAT. I know Intel at one point explicitly banned manufacturers releasing empty M.2 enclosures. Seems like this is a very new development, looks like mid-Dec 2017.

That's fantastic. Absolutely fantastic. Do you know what this is? Portable 4K framegrabber, just add Magewell Eco Capture HDMI 4K M.2. YUMMY. Want. WAAAAAANT! Alas CRA has dibs on my money and then the Lenovo G0A1. This needs to wait, looks like over 700 USD but still, a portable 4K framegrabber for less than 800, that's... incredible. The next comparable device is a grand and rack size. Not portable, LOL.

Also, I must note this is the first affordable TB3-to-dual PCIe, just needs breakout boards for both slots.

@Sprober: Thank you so much!

I tried to record the noise with a shotgun microphone, here's the result:

The thing is that the noise isn't loud in terms of decibel - it's just incredibly annoying. I doubt that it is somehow broken, but when you're saying that yours is "whisper quiet"... I can definitely not work on audio related stuff when there's a constant high-pitched noise in the background. Mine is definitely not whisper quiet.

Again, many thanks - especially regarding the driveDX idea!!

Cheers;
Jon

... and here's the update regarding the idea of unplugging the fan from the disk:

The setup:
I started....

  • BM Disk Speed Test
  • FCPX for a large file export
  • multiple file copy processes
  • VLC to playback a bunch of movie files

At the same time, I was monitoring the "composite temperatur" (NA611TB3 case), "Temperatur Sensor 1" (probably first m.2) and "Temperature Sensor 2" (probably second m.2):

The max temperature I was able to measure:

  • composite temperatur: 39°C
  • Temperatur Sensor 1: 42°C
  • Temperatur Sensor 2: 56°C

I'm not sure if 56°C is too high... but on the other hand: Everything below 70°C seems to be quite ok...

@J0n I would think as long as you are well under 70° C you should be fine. The environmental specs directly from Samsung for the 960 PRO are below and 70° is the point where it throttles performance though running at excessive temperature may effect lifetime(?). Was it the fan creating the noise, did disconnecting it resolve this?

Environment

AVERAGE POWER CONSUMPTION

I would definitely be annoyed by the sound in your video for audio recording however I have all of my computer equipment on a shelf in a 19" rack with a door as my eGPU does have fan noise for sure.

@chx That is a really good idea about the Magewell, it may work. You would have to make a cut out on the back for the HDMI cable and remove it's heat shield put a 2 TB SSD in the other slot, best of both worlds. I bought this so I would have a decent amount of somewhat portable fast audio and 4k storage, paid around 270£ for it and had the NVMe's.

And here's the official response from Netstor:

Netstor team has thoughtfully designed the short moment (few seconds) full fan speed feature to the rear 2x2 cm fan of the Netstor unit.  The few second to provide full voltage to Fan cooler when you power on NA611TB design, is to make sure the Fan cooler spinning up. The reason that our team has this feature be designed in is because the feature of the short moment (few seconds) full fan speed will prevent the 2x2 cm fan from aging; it will keep the 2x2 cm fan work longer, the lifespan longer, and the fan working right all the time. 

Normally, users will have the Netstor NA611TB3 unit be powered on along with the Thunderbolt 3 Mac, that is, to power on Thunderbolt 3 Mac, and the NA611TB3 will power on along automatically. The user can follow the above described power on procedure, and the short moment full fan speed to the 2x2 cm fan will only occur for a few seconds just right after pressing iMac’s power button.

 

Secondly, please visit the following site for the NA611TB3 video: 

 

During time period 2:15 ~ 2:20 in the video, it has instructed the users how to check if the power button is with the right position just right after inserting the backplane into the storage enclosure. Please have the user check the unit’s power button by the instruction told during the time period 2:15 ~ 2:20 in the video content.

Lastly, each brand, model of M.2 SSDs has different thermal design.

If the M.2 SSD to be used with the storage unit has lower thermal design, the rear 2x2 cm fan at NA611TB3 can be disabled by not connecting the fan power cable within the Netstor unit, but the thermal pad inside the NA611TB3 must be always used for the M.2 SSDs for thermal conduction and dissipation. 

Note if the M.2 SSD to be used with the storage unit has higher thermal design, under the circumstances the thermal pad inside is used for the M.2 SSDs and the rear 2x2 cm fan is disabled, it will be ok if the M.2 SSDs’ temp goes high while working because as the M.2 SSDs’ temp goes high above certain level, the M.2 SSDs’ controller will automatically down-clock to enter the protection mode; the only effect will be the write performance to go down to have the M.2 SSD work without generating much heat.

Hey guys, just stumbled upon this thread whilst looking at thunderbolt 3 interfaces and I was wondering if the write performance of this set up was due to the PCIe 3 interface on the NetStor enclosure being 3x2 and the 960 pro being 3x4. 

From Scan.co.uk "The NA611TB3 can be equipped with two M.2 PCIe NVMe flash storage modules with each module having PCIe 3.0 x2 lanes up to 16Gbps throughput. Moreover, the dual M.2 modules can further choose to be configured for software array as RAID 0 in favor of performance or RAID 1 in support of security."

Please correct me if I've misunderstood, I'm only just starting to learn about PCIe and SSD technology instead of taking it for granted!
