Well after a week in the DC, I can clearly state these tubes SUCK!! total junk!! Unreliable heat MONSTERS!!
Out of 40 boards 10 are severely under performing and I had 1 start on fire today. Now to see IF the RMA process is as botched as the sales process.

Sorry for your mining operation, but now you see why is it worth to pay a bit more for some reliable and stable miners?
