Would it be a difficult operation to re-paste the A1246 hash board heat sink?
That would be my suggestion for a fix procedure.

You have one chip reporting the 91C temperature (in the first hash board, see PVT_T0 values). Maybe a bad asic chip or a bad contact with the heat sink?
The TMax literally just shows the highest reading among all the chips.

Do they have a different pinout in the 4-pin fan connector compared to the usual?

Yes the S9k has had a huge failure rate, the other S9 variants work better.

I think it's ridicculous that they even keep the web shop open because nowadays they don't have anything for sale most of the time, and when they do, the lead time is like 1/2 years.

They should just shut down the web shop.

Here is one article for gpu: https://www.overclockers.com/the-oven-trick-repairing-your-broken-video-card-with-an-oven/

I haven't tested this so I'M UNABLE TO GIVE MY REVIEW FOR THE PROCESS AND ALL THE RISKS ARE YOUR OWN.

I would recommend using an oven in which you don't cook your food.

Send the pictures here at the forum!

Has anyone considered putting their bad hash board to oven as some people do for GPUs? In hopes of re-soldering it.

Also, DJ Miner (distributor) says that the P21 can be used with the M10

There are so many T3 variants that you might want to describe which T3 variant you have exactly.

Would you care to share what fixed it?
So that other people with same problem can find help from your solution.

One more thing to mention, that while looking at the Digikey site,
I also found Sunon PFE0381BX-000U-S99 which is also comparable and about ten bucks lower price than Delta.

Glad to help.

These seem to be hard to find from somewhere else than China,
for good price.

AVC DBPC1438B2H (one model that I know Canaan has used),
I only found listings in Aliexpress and some other Chinese marketplaces.

Delta PFM1412DEB7V (one that I found to be comparable with the AVC one),
this has quite good availability but eg. Digikey asks 54 bucks for one.

IT IS NOT A BITCOIN MINER!

@ZimbaCardi
Have you asked Zeusbtc if they have any?

Have you considered reaching Canaan directly?
https://canaan.io/product/a1246
Their sales email: sales@canaan.io

EDIT: Woop woop, this is my 3500th post. 

I've bought gear few times from Eastshore without issues.

The Canaan distributor in Europe is Cryptouniverse from Vienna, Austria. www.cryptouniverse.at
But I'm not sure if they still sell gear. Or if they just havent updated the website for a while.
I've bought gear from them as well and it went smooth.

@kalov91
That site you linked is a scam!
Please remove it.

@astraleureka
That's a valuable warning. Thank you!
