My friends, you right , but I tested with 1 hashboard , 2 hashboards and 3 hashboards, all of them have this error
Changed control board with another one, changed pau with another one, changes all fans, but this error is still and Miner can't work more than 1 minute

Thank you friends

I opened it, all heat sinks are safe , I thought may be silicon's may be removed, I pulished every chips with Z9 silicon, but the problem isn't remove

All fans work correctly in 500cfm
Room is not closed
Air come in and out in best positions
Other S19PRO work in this room correctly,just  this one has problem

I set fans on 100%, but didn't work more than 1 minute.
It's my kernel

Hi friends

I have some Aisen A1 miners. This devices , after failed power supply, control board will make problem too.

How can I recover this kind of control boards after repair power supply.

Sorry !!!

Who has NAND file of this device model ??  

I did do them one by one

But nothing happened.

Do I need to reprogram NAND ?

If yes who has NAND program of this IC? 29F2G08ABAEA

Thank you

but this control board doesn't have any jumper 

Hello friends

How can I downgrade my S11.

It can't get IP
