My pump died within 2 months of batch 2!
I've emailed bitmain for rma details...
Anyone else had this problem in batch 2??
It's a painful process with syscooling. They will want multiple videos of troubleshooting it with various tutorials that they forward to you. It could take over two weeks. My pump was DOA and after back and forth I bought a XSPC that is build much better. Although at about 70 usd.
Careful with those, I've had about 20 failed XSPC pumps over the years, at least. The good high quality pumps tend to cost an arm and a leg unfortunately, so XSPC always looks enticing.
