Given the problems some folks have had running it on High, not a good idea.

For 1 your would need to improve the airflow through it.

More in line with reported problems there is then the point of how much power the USB-C PD circuit in it can handle. In most cases the power flows from connector directly into and through the PD negotiation chip reported as chip-5. If the PSU says it can provide it, that can be up to either 28V for the nano or 42VDC for other devices @either 3.5 or 5A for either voltage. Some folks have reported that the chip can get too warm and develop bad solder connections so I would not recommend pushing it.

[botor123]

I've been using them for 1 month on HIGH and I have no problems. both covers are down and I have temps between 32 and 50 degrees. i also have a BITAXE where you can play around with the voltages and frequency...so if the chip has a bit to spare...

[ya5on]

I can't explain it.
For some people the device works without problems, for others it doesn't.
What could be the reason for this? Has the design of some devices been changed, different chips used or something similar?

Agreed. I've posted here before, and wonder a lot about why it be so very different from user to user?
(For instance what is the point of having a high setting when it only works on, let' say... 1-5% of all devices? What is the reason for it NOT working on high for the rest of us?)

because the design depends a quality usb-c cables with a proper chip inside them.

Also constant 24/7/365 power draw keeps a lot of heat on the chip in the unit and the usb-c cable's chip.


This gear will not last at high without an effort to cool the 2 chips.

Stupid design flaw.

best way to understand this is to put an infra-red temp and check the heat where the 2 chips meet.

shame as I do like it. I suspect this will break on me this winter as I have run them near an ac/heat vent once the heat comes up in the winter I think these will break.

Would love to see them keep track of the best share in the GUI / Pool stats that the miner has submitted since running as well as best per session.

You do get a glimpse of the best share per session in the logs but unfortunately those get wiped out after every reboot.

Point it at kano.is if you want permanent stats. It shows the best so far for my Nano is 3.9127G on 9/14 @ 2.21p EST.

Mad respect for Kano but this should really be available in the Avalon GUI so that every Nano user can have a check and balance of all pools.

[NotFuzzyWarm]

Can't say any miner GUI shows best share. If they do odds are the record is erased on a restart/reboot. fyi, the flash memory in most micro-controllers has a very limited life - many are only good for just a few thousand writes at best - so not a good idea to store records in the micro's flash.

We'll agree to disagree on this one.

For a reference the open source AxeOS does this exact thing with the Bitaxe miners. Although not what many would deem a commercial miner it does work.

Besides it's still never a bad idea to have a check and balance on what pools are reporting.

hello.is there a possibility to overclock the device?...for example to reach 4.5T?

If you watch the UI of Nano, manytime at high mode it reaches 4.2 T. I thing pushing it over the limit might harm the device.

Hello, impossible so far.

[Canaan Online Shop]

Hi,
is there an api from which I can get the Miner-Info?
With the adress <IP-of-miner>/get_minerinfo.cgi I cannot get any information from remote if i am not logged in. If I put the adress in Chrome, i get all the providet infos but I would have the information in iobroker or FHEM (or something else) with RegEx an parser.
Greetings

Hello, Nano3 currently does not have this function.

[Zzorb]

Hi,

I have a Avalon Nano 3 and I have a suggestion that it will be good for me and I believe other users too.
When it disconnects from the Wi-fi it stay in High for ever and ever.
Can you add a firmware where when it disconnect from wi-fi it will go automatically to idle?
This will avoid using electricity for nothing and will increase the life time of the Nano 3.

Another thing is, fans are getting dusty already. Is there a tutorial to disassemble it to clean?

Thank you

[Exist2Resist]

Dear all
If you have questions related to Nano3, you can share them here.  We will collect questions and provide timely feedback to our team.
Thank you for your support.

Why is the nano 3 so loud on High fan setting?
I thought it was supposed to be quiet, all I hear is a loud fan wine.

Give us a way to control the fan based on a schedule.

[NotFuzzyWarm]

Despite it's tag saying "Air speed", high is NOT setting the fan speed - it is setting the speed & power of the miner. The fan just runs faster to keep the miner cool. Drop it down to Medium and the fan will in turn slow down and become quiet.

A better way to understand this is about driving your car.

My hyundai sonata hybrid can go about 105 miles an hour or around 170 kilometers an hour.

do I choose to drive it at that speed ? no

your nano can run at high speed. I would estimate constant running at high speed on the nano is like drive my sonata at say 95 miles an hour maybe 152 kilometers and hour.

Doable yes doable for hours yes.

smart no as long term life and wear and tear will take out the gear.

So I set my sonata hybrid at 66 miles an hour about 101 kilometers an hour.

Wear and tear less miles per gallon better.

this is why anyone running the nano at full speed right now is not helping their bottom line.

now if ordinals make blocks have 5 coin rewards yeah crank the gear up.

just like if there is a tornado behind you on the highway drive at 90 or 105 mph to save yourself.


This is not at fuzzy it is at all that want to run at highspeed for no great reason.

I am trying to get my unit to work properly. I have it on an isolated LAN with no open Internet access and no DNS. It does connect to my stratum server and starts mining. However I see that it queries for 0.pool.ntp.org, 1.pool.ntp.org and 2.pool.ntp.org and after a maybe 30 mins mining it stop and all it does is querying for DHCP. So I have a few questions:

1) How can I change the ntp servers it is querying to a local IP?
2) Is it expected that it disconnects after a while if it can't reach NTP or DNS and that it keeps querying DHCP like it does?

Thanks!

Ok I redirected the Nano to my local NTP server through DNS and it now gets the time properly. However I am experiencing the same Wi-Fi issue as others. The miner works for a while, then somehow loses Wi-FI and is unable to recover most of the time without a reboot. Sometimes it does recover after a few minutes though? I tried moving it right next to my router as a test to see if it is more stable. I tried using a fixed channel as well...

Edit: Neither of these tests (Moving it closer to the router, fixed channel number) seem to fix the issue  . Looks like they have a firmware bug. So far I don't think I got more than 15 minutes out of it without a reboot. It does not seem to depend on the hashing power.

Edit2: I tried tcpdumping my interface on the router. Here is the sequence I see:
1- The miner does an ARP request to the gateway / DHCP / DNS server
2 - The gateway / DHCP / DNS server sends an ARP reply
3- The miner does an BOOTP/DHCP, Request to the DHCP server
4 - The DHCP server sends BOOTP/DHCP, Reply (multiple times)
5 - The miner does not respond

[Jodmapht]

So far it seems my miner has been online between one third and one half of the time, spending the remaining time indicating it is not connected on the Wi-Fi. I do not have any Wi-Fi issue with my other devices. Sometimes the miner recovers after 5 minutes. Other times it takes much longer... Do you experience a similar behavior? Wondering if there is any Wi-Fi router parameter or stratum server setting or pinging of the router that would help in preventing the issue from occurring until they Canaan fix their firmware?

I have the feeling that the miner drops when the IP activity with the network is too low. It seems that it might be dropping less if I have a browser pointing to its dashboard?

Edit: So far it definitely seems that artificially generating more network activity with the miner has a very positive impact on its ability to remain on the network.
Edit2: I have been using ping -W 1 on the miner for over 3 hours and no issue at all compared to it not running over 30 mins straight before. Anyone that has similar issues should consider giving this a try. This does not fix the root cause, but at least it makes it usable. Will have to figure out if a Wi-Fi or DHCP setting on the router can fix the issue, or if it is really a bug that has to be addressed in the miner's firmware.
