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.io

mention the forum

Thats unacceptable. They are two new guys,  but still un acceptable

Thank you Steven, email sent

Jasmine and Lily  are on it.

I'm getting on a plane  I will check when I land  tommorrow


Steve, The fan arrived today, I installed it and all works great.  Thanks for stepping in to help!

@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.


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?

And,

 I had swapped out to a different PI, with a new sim card, no change
I bought a better PI power supply , no change.
I reverted to a previous PI controller version, had no affect.

Just a bad fan.

HagssFIN found the power used to be 1382W here - https://bitcointalk.org/index.php?topic=2588105.0
You may want to try a larger PSU as the EVGA could be struggling to power the 741.

^^This is a good suggestion. Try setting the miner to operate a -2 and see if that drops the required amperage enough for it to bring the fan online.

I was running two 741s set at -1 off of a Delta 240V 2400W PSU and never had any issues. They were also on a dedicated 30amp circuit.

If you're running 120V, then your single 741 pulling like 9.5 amps. You're probably on a 15amp circuit. Is anything else taking current from that circuit?

Toughit if you are on this page then no it does not refresh, it is normal:



on the bottom left hand corner it has a link to change theme, click on it and it will give you the page that automatically updates.

I’m posting here because I hope it gets noticed by Steve Mosher.
I ordered 6 Avalon 741’s from miner warez on October 25th  I’ve been waiting and have been told
For the last 70 days my orders are promised and secured. But I received an email yesterday that they won’t be able to fill the orders and that I can get a discount on some 821s but that I’ll have to wait until March.

I feel you’re reneging on the deal I’ve already waited 70 days, and since this is an investors game I don’t want today’s pricing on miners. I want October’s pricing.


Let me know if you’re going to do the right thing.

Well, tested the fan today. At least I know the fan is bad! Tried with multiple pc's ect.. same results everytime.

I tried reducing the voltage to -1/-2 not for sure if it helped much, the miner still got hot at the same rate. I am definitely replacing the fan though.
I have the avalon 741 on its own outlet, I will be testing the outlet today to see if the power is good.

Fan stats:
Avalon 741-Cooler Master pull, 120x120mm x38mm, 12VDC 2,7A, A12038-60BB-4RP-F1

Thinking this fan might be ok... https://www.amazon.com/gp/product/B076CVBK55/ref=as_li_qf_sp_asin_il_tl?ie=UTF8&tag=cryptounivers-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B076CVBK55&linkId=c5fb1b490f79c83223c1aac8deed848a
Would the size difference matter?..
I see a suggestion for  https://www.amazon.com/gp/product/B00QWB1X3O/ref=as_li_qf_sp_asin_il_tl?ie=UTF8&tag=cryptounivers-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B00QWB1X3O&linkId=2d035699d78dedadfdcd9e82ff1b5e6a
but the price difference. Would prefer a good fan(same stats) that works and I can get fairly quickly.

Open to suggestions, Thanks for the help.

Yeah, that Delta QFR1212GHE will do the job just fine.  Smiley
https://www.amazon.com/gp/product/B076CVBK55/

And that Sanyo 9GV1212P1J091 is a good quality fan as well, I used to have one with the Avalon6 miner.
https://www.amazon.com/gp/product/B00QWB1X3O/

These are pretty much equally good options for a replacement cooling fan.

The replacement fan sent from Avalon was a Delta, I think it was the one mentioned above by HagssFIN, but I did not look before I installed it.

They did not send a coolermaster (the original fan in the unit)

I always thought that unless something is broken there is no reason to risk upgrading.
However, it is wise to download all the update files and save them - learned that one from Bitmain who likes to remove updates and make them no longer available!

I guess if there are no real performance improvements I will stick with current version...

the list of updates looked pretty short, like a stop/start button added

Have you tried just hitting restart on cgminer or rebooting the entire system from the advanced dashboard instead of actually unplugging it?

Guys I also have a 741 that keeps heating up every 2 to 3 minutes. It will hit around 100 C and then the fan will kick in to 100% to cool it off and then it will go right back down but will start working its way up. I contacted Canaan about it but was extremely let down with their service department.  At first they told me not to worry about it but I told them this would wear the fan out quicker than it normally would, then they told me they would send me a hash board. So I've received a hash board from them but I'm honestly not sure which one I need to replace. If I give you guys the log, will you be able to point me towards which one might need replaced? I'm not very well versed in the 741's
