while its running, pull the board furthest from the psu (number 1)

it will continue to hash and you can work on that one blade and check the thermal paste, i can almost guarantee its been applied poorly.

if so, reapply and shove it back in (not necessary to power down though the inexperienced will disagree)

if its still freaking after you pamper it, get on to bitmain and send it back for a better blade (no need to send the heatsink)

check the S2 SOLD OUT thread for images of the thermal paste applied in house

best of luck, stay in touch

After monitoring for few days i can safely report it was thermal paste issue.

When i removed the board's heatsink..almost 1/4 of the chips were not covered by paste at all..

I reapplied nicely and no downtime ever since, thanks edgar

I would recommend Antec 7 thermal compound it has dropped my boards temperatures quite a bit.

Use alcohol to remove the old compound.

Over the last month my S2 randomly stops hashing. After a single reboot everything is fine.

When i log in this is what i get:



Board temperatures are around 60℃ average and the "Stop running when temperature is over 80℃" option is disabled.

The room is not air-conditioned but this never stopped the S1's and S3's do their job.

Thoughts?
