Blockstream CSO Announces Technical Issues with Bitmain’s S17/T17 Antminer, Resulting in High Failure Rate

The Blockstream Chief Strategic Officer (CSO), Samson Mow, has recently shared some alarming news from the community of bitcoin miners who use rigs from Bitmain, the world’s largest manufacturer of crypto mining equipment.  Mow announced on April 26 through his official twitter account that, miners are reporting technical issues with Bitmain’s Antminer S17 and T17. 

According to him, bitcoin miners who rely on the Bitmain S17 and T17 Antminer have said that the rigs have failure rates between 20% to 30%, instead of the normal 5%. Mow Claimed the miners are reporting that heat sinks on the Antminer S17 and T17 rigs have been falling off. 

Furthermore, Mow said users have reported problems with the power supply fans on the Antminer S17 and T17. Both the heat sinks and power supply fans are normally designed to transfer the heat generated by the rigs. As a result, almost one-third of the mining machines have been shorted out by the reported problems. 

In the tweet, Mow also highlighted that Bitmain Chief Executive Officer, Jihan Wu, blames fellow Bitmain co-founder MicreeZhan for the above problems. Zhan was ousted from the mining rig producing company by Wu in October last year. At that time, Wu pointed out that Zhan was responsible for the wrong direction in research due to his self-centered approach. With the release of the new Antminer S19 series, Bitmain hopes its customers will have a better experience. 

Both the Antminer S17 and Antminer T17 were released by Bitmain in the second quarter of 2019. They account for a significant share of SHA-256 ASICs worldwide. According to data from ASIC Miner Value, Bitmain’s Antminer S17 is among the few ASICs that remains profitable, even after the recent historic price crash.
