the s7 and s9 was a bad design.. thermally.
the heatsinks right behind the fan in the center by the motor part of the fan get no air at all..
they should have added a 1 inch spacer on the intake and exhaust fan to help, but even then those front sinks are in a dead spot.
also having those tiny heatsinks all over the place not even lined up is not helping either.
at the very least they should have made some jig to hold the heatsinks and make them all perfectly lined up.

My mod should fix this as the unit will be a little longer.
yes something like this 3d printed that channeled the air through the miner would be pretty helpful.

my goal is to make two miners.
order a second controller. so you get a 2 board miner fully stock
and pull one board cut the post to length from mount it here and you get a one board miner which you can downclock run in house and it needs under a 750 watt psu.
Cost is not bad and if you have 5 or 6 s9s like I do this gives you spare parts plus let you tinker.

But if you look at failed boards, he's 2 of 9 for 22% failures.
....
....
If I look my 9 replaced S9 boards from 23 miners , it is only 6 broken miners from 23, that is 26%
If I Calculating from broken boards, than it is 9 from total 69 boards = only 13%
The fact is, that today is the first day, if I have all 69 hashboards in my hands.
From the first day one or more hashboards were on their way to China, or back . But I was never missing more than 3 hashboards at a time.
It does only one or less broken miner from 23. Only 4,75% in the three-month period.

Also, I would bet the heatsinks were removed on those boards because right in front of the fan the topside heatsinks will be sufficient, and removing the backside heatsinks especially right near the fan motor will improve airflow (less backpressure and ducting) for heatsinks farther down the board and keep the whole thing cooler overall.

i moved the board to another machine and it failed also after 30 minutes
i sent it to them, it's second board dead from 3 S9 that mean 20% damages
I think that your not working miners % is 66% , if you have only one miner perfectly fine.

bitmain remove about 8 from this small pieces used to dissipate Chip temperature ( i don't know it's name )
on S9/550 to make it higher temp than S9/600 and sell it on different batch
that what i saw when i opened my B12 today

today one of my 2 antminer s9 B12 get dead board with XXX status
after restart it work for 15 minutes and stop again
any idea ??

You can swap the psu's for each machine. then check and see if the problem follows the psu if the problem follows the psu it is a psu issue.
So swap psus and get back to us if the same board fails or not .

if the hash PCB works on different data cable or different data cable connection slot, please use the different cable and confirm the data cable is not the problem
This will help you eliminate problem. IF you have another S9, you can always swap out with known working C5 or control PCB module set and see if all works okay with the known control or just the problem remain with the IO board.

how you guys check IO board or BB board need to be replaced? or you just replace both IO board and BB board?
I know for sure its not my Hashing boards because when I switch the connection cable on IO board the miner is hashing nicely, but only last 1 day..

Bitmaintech.com and enshop.bitmain.com/product.htm are up again.
s9 is still sold out.

Yeah, and making them put work into warranty support on top of it!

Bitmain going into "BW.com road" by not selling the miners for public anymore?
Wouldn't blame them one bit...all you home miners driving up the diff & keeping the corp miners from making profit...you should be ashamed of yourselves
