Hi Guys.
I've replaced the 2nd psu. still not luck. checked the connectors. found that the 1st psu cpu connector was slightly loose. pushed in and much better as the 2nd fan also started to work. however, only the other blade was now working.
switched off and replaced 2nd psu to stock.
Now it don't hash at all. no info for fans or anything. any ideas ? Im think its the controller board.

Hi Twib2,
Thanks for the info. checked the pcie and cpu cables are in the correct sockets. may be the psu.
I'll try another 1000w psu in the morning.

Your second blade is not hashing - if the 2nd stock PSU is really fine, then maybe a power issue from the connector board? If you have a PCIe swapped with the CPU plug, that can also do that. Luckily if it's a BTMine unit, there's protection and all you have to do is get them in the right connectors and you're good to go. My guess is that both stock PSUs died, one more convincingly than the other. If you have another high-watt PSU, I'd try plopping that in place of the remaining stock PSU.

My MinerNo2 Stock PSUs @ 1300 Freq, recently started dropping hash rate down to almost 0 then went back to 190Ghz. Dropped like this a few times and finally today temperature went really high upto 70C and hash rate dropped to half speed around 95ghz and fan pushing air out stopped too.
Switched off and replaced one of the stock PSU with a 1000W EVGA PSU 80+amps single rail.
Switched back ON and still same 95Ghz or so and 1 fan still don't work.
I have checked the FUSEs on all the modules and all are good.
Looks like 1 blade is totally dead - miners 9-16 :-(

Still searching this forum.
Hope someone can advise a possible fix.
