So chip / heatsink issue on most of units, and yet Bitmain claims if heatsink is loose or chip is burned that warranty for that board is voided, so sad.
AFAIK that website wasn't changed since era of S9's. For T/S17 gear they know they fk-ed up and are replacing whole units without any real questions. For my S17 Pro (out of warranty) "repair" cost me $60 which is less than 40% of what I paid for shipping, so I was happy. But for bigger farms, I guess they do not even ask and just replace it with new unit for free.
