For you guys that just got your M3s, can you confirm that the 3 pin connector is reversed from the instructions? I know this is trivial, and I have seated the connector so it looks to be in place correctly. But I am OCD when it comes to instructions and I HATE it when what I have is different.

Here's the manual




And then here's what I have

Maybe the manual is incorrect. It connects in the same fashion as the fan header connection. The "slot" slides against the white
tab, and the 3 "metal windows" face the fan headers.

Something must be up 'cause both mine are running really really hot. Right next to my S9s that are 69-72 deg C.

I'm not saying there isn't, but remember, these little beasts are pushing 2000w of power. The reaction of all that hashing energy,
is heat. Just monitor it, and make sure it doesn't go much higher. I'm welcoming the extra heat here in Snowmans land! Hahaha!

Yeah, but these are bouncing off 86C. But it does say wait 15 min while it runs through its test cycle so I will.

Took this snip from Haggsfin's review thread:

Snip:

Hi . I have bought one . But i have problem in this miner it reboot automatically after few minutes and never reach 9.3th . Also the fans speed are too slow its 1290 in , so the temperature adjust to over 80C and then after few minutes it shut down and reebot automatically . Whats the problem with this whatsminer M3 ??

I had the same issue with mine, I’ve added a vent bracket and a direct 3m duct outside, this has solved the shutdown issues, it’s still running at 83degrees, 11.5/th

[Raymond_B]

All my M3's are usually sitting at about 83.5 to 85c.  Right above them in the rack I have two S9's that are seeing highs around 59c.  Above that are two A741's and they show 33c/75c.  The cold side of the room is around 22c.  I haven't noticed any problems so far.

Also all my units have a 6" diameter duct going out though the wall into the hot side of my mining room. 

My fans are running around 4k.

Thank you, mine are in that range too. I did not realize how hot these ran in comparison to the Antminers. But like Shazam!!! said they are pushing over 2k watts.

The logic of their software is interesting too, it looks like they will hash as fast as 85C will allow and then back off. Avg is almost 12 TH/s though so just as advertised.

Yeah, I saw his review and went through some pages, I need to take my own advice and search better

got mine today too. Ran well for about 2 hours. When to change the pools and did a reboot. Now it wont start. I can access the web page but it Just says waiting for Cgminer to start. let it sit for 10 minutes and it is so hot i can hardly touch it.
Looks like i will be checking with them on the warranty. Unfortunate after waiting 4 weeks for this thing.

Try doing a full reset. Like I mentioned previously, these things are past being a space heater, they are full on blow torches So yes they get so hot you can hardly touch them. I actually had to remove the 6" duct adapters my buddy made as the 85C heat deformed them. I need to check and see what material he used.

[ternzer]

Thanks for the idea. I tried a reset but it didnt work. The status screen is all blanks.
this is in the CGminer spot on the overview page - unknown(waiting cgminer to start)

I have tried the restart CGminer button in the system tab but no luck.

I got a good 2 hours at 11.6 T/s. now nothing.  

the logs appear to indicate that the miner and the cores are OK. Has anyone tried to re-load the firmware or CGminer? The firmware on their site is older than the one in the miner.

Has anyone tried to submit a ticket on their site? I did open a ticket. Or is there a better way to ask about support/warranty?

[ternzer]

I found the problem. I did some searching around the internet and saw a few people had a similar problem but no solutions. So i started reading the miner system logs from the bottom up. I found a line before the CGminer exit lines with port not open...
So...I use awesome miner to monitor the miners. I changed the port to 4028 for the API access. When i did the hard reset this port did NOT revert back to 22.

After switching it back i restarted CGminer in the interface and it fired back up!.

I'm up and running. I had one, little hiccup, with the cgminer gui. It did not want to accept a pool change, and would not start.
 Did a reset, and it took care of it. Also, where I'm at, it's about 20 degrees Fahrenheit. I had to put them in the garage temporarily,
and it took some time for them to heat up completely. So far, everything is working as it should. I'm seeing speeds at/near 13th/s.

In that cold air what temps are you seeing?

[Shazam!!!]

In that cold air what temps are you seeing?

Right now, at 32(23 real) outside and 55 in the garage, I'm getting inbetween 77 to 84, depending on the wind gusts really. The ole
garage isn't quite air tight, and I literally have nothing behind my house but open fields, for 2 miles. I've been monitoring them for
about 15hrs, and they've been very consistent since they warmed up. Still getting 11.9 -12.8 th/s.

Good info thanks! These things like to run at high 70s to mid 80s regardless of the ambient temp it seems. I was getting almost the exact temps as you with 60 ish deg intake air. Today it was in the mid 60s and my garage heated up to mid 70s so they are running anywhere from 81-85.

No problem. I can say, earlier this afternoon, my temps were staying above 80, and I was seeing consistent speeds from
12.5 - 13th/s. Theses seem to do their best work, when they can heat up some Hot Chocolate! Hahaha!

Hello! Please tell me, one of the miners works for 6 minutes and will reboot. I have voltage regulators, no voltage surges. What could be wrong?

Disconnect one hashing board from power supply and check if miner is working fine with only two.

What are you running for your voltage? 120 or 240? Also, in cgminer, check the system log for the reboot error.
