Just received a shipment from avalon, it was supposed to contain a new fan.
Instead the package has a fan shroud!
2.5 weeks down on a brand new miner.
send me mail steve@canaan.iomention the forum Thats unacceptable. They are two new guys, but still un acceptable

Personally, I am not a fan of the integrated PSU. PSUs go bad- that is the nature of the beast. Now when one craps out- the whole unit is dead vs being able to swap it out in 30 seconds.
The front of the unit comes off and there are two terminals to wire a PSU into the device in case the internal PSU craps out. This was my biggest concern. PSUs tend to be less reliable than the miners, so it was imperative that if the Integrated PSU craps out that we be able to quickly supply power from an external one. Basically 2 screws and your there. After a few months in the field I'll have revised in field failure rates of the integrated PSU. For now I'm restricting sales of the 761 ( it sold out ) so I can monitor closely.. Later in 2018 there will be an 861 Thanks for that information. I have had 3 HP PSUs crap out this month but miners are working no problem. Good to know there is an easy fix to the internal PSU issue.

Hi,
Trying to get my avalon 741 running. I've watched the setup videos ect. My psu is the evga 1300w g2 (recommended for U.S. outlet 120/240v). The psu is on its own outlet, avalons boards are green light, AUC3 is geen & blue, the top light on the avalon is blue(goes yellow/green sometimes).
PROBLEM:My fan on the avalon starts and stops. Maybe a power issue? Bad fan ?
Any help is appreciated! ~Thanks

Does it completely stop? How much time are you waiting as there is a ramp up period.
Do you have your pool information entered into the controller?

It will turn it off if it's not needed. Is it running? You can log into the miner and set the minimum percent power on the fan. If you're in a cool climate, try 10%.

I've logged into the Avalon controller but no, I haven't specifically added a pool. I've hooked everything up. From the setup video I've seen, the fan/Avalon should power on and run even without mining. I've let it run for a short amount of time just minutes maybe 10-15, the fan starts and stops repetitively. I turned it off because the Avalon was beginning to get warm/hot.

First you need to enter a pool to mine from so the miner will ramp up. When you click on advance on the controller main page you can find this tab on the top: The yellow allows you to adjust the fan speed.

So definitely enter your pool info then it will actually run and keep the fan speed up as needed. The fan is variable speed so without making the chips work it will cycle like you were saying. The miner will get warm but you can monitor the temps from your miner status page in the advanced view, you just change the theme from the main page when you first log in.

Thanks for the replies.
I finally got the 741 configured and mining... only for moments. I'm glad to see that mine is actually working. However, my issue seem exactly like Toughits. My fan doesn't seem to work. The fan tries to work on start-up, but stops. (opened a ticket already with canaan) Should I just buy a new fan? Is it the Rasp Pi 3 controller issue?
Thanks for the help. So close to start Asic mining >.<...

How long do you leave it mining and what temp do the cards get up to? How cold is it where you live?
Finally, set the minimum fan speed to like 20% so it shouldn’t ever turn all the way off.

Can you post your API log and your miner status, when it is running and then again after it has shut off to compare. It just seems weird that the fan runs then stops all together. In your ticket to Canaan you can ask them about opening the case to make sure the fan cable isn't loose. But like any product under warranty get permission first. Also give them all info required they are really good about getting parts sent out quickly depending on how busy they are.

@Didley1JT -The miner is only on for maybe 4minutes at a time. I start it up, the fan starts/stops.. all the lights look correct. The blue light is on and its mining. (well getting pennies added to the wallet) I'm getting use to the Openwrt/Avalon software, xD I don't see the temp reading for the miner. The temp (since I'm testing indoors) is room-temp around 70/72. I have my own fan/ac units that would cool it, also a place for equipment on my balcony (30 below outside) if I can get the fan working. I adjusted the fan speed to 50 and (default is 10) nothing happens.
@Steamtyme- Where do I find the sou log? I added the request to canaan. I believe, I'm having the same issue as Toughits, if the fan is the problem and not the pi3 firmware then idc to just buy a new fan. Within just a few minutes of having the miner on (4 or 5) the Avalon 741 gets extremely... warm/hot.
Equipment: Avalon 741 ,Evga 1300w g2(I use the EVGA Detection Tool as the paper clip),Ras pi3,and auc3 converter. Using nicehash pool to mine < also how I verify it does work for a few moments before getting hot.

Remember to take into account the power supply efficiency. Let's say the power supply efficiency when at almost full load is something like 90% and power at wall is 1382W. This means that the power at the 12VDC rail is about 1244W. But it is true that you might want to leave some more room in there when using a ATX psu. You can setup the Avalon voltage offset to -1 to slightly reduce the performance and power consumption. If you can measure your power consumption at wall and you know the power supply efficiency graph, you can also do this calculation to check the situation by yourself.

Lance- I got my replacement fan today and it works fine. Try this: hold the fan in one hand and spin with the other hand. My bad one has a noticeable hitch or bump as it spins. The new spins with no hitch. I tested the old (now bad) fan by using a 9v battery and plugging into the red/black wires. Without a PWM signal the fan should go to 100%. This fan sometimes starts, sometimes does not...

Also, my miner would connect to the pool (blue light on the miner) and hash just fine, but the temp would keep increasing. You could see in the cgminer monitor that the PI was increasing the fan speed, but the fan was not responding. Eventually the miner got too hot and shut down).
By the way, I have to keep refreshing the cgminer monitor, it does not automatically update the numbers, is this normal?
