That is another lie, a while ago i linked an article which was likely translated from a Chinese one, that talked about Chinese miners complain about the exact same problem we all have 'heatsinks/chips falling apart', apparently the mining whales in China have some private WeChat groups, and that's where Jihan Wu hangs around, Jihan Wu begged the Chinese miners to give bitmain another chance with the S19 after admitting the 17 series had some major quality issues, those reports came from CHINA from CHINESE miners, so saying "new miners rarely have such problems in china is a straight out lie" unless he thinks that 30% or higher failure rate is considered "rare".

This, of course, does not negate the fact that the Chinese miners get a special pass, Jihan Wu never apologized or begged us, he probably never bothers about the forum, or other non-Chinese groups on telegram and Facebook, but when the Chinese miners complain he listens, heck he even offered to send them staff on site to have the faulty 17 series fixed at NO cost.
