As one of many largest mining facilities in the USA, Texas has traditionally been a strategic cornerstone for Bitmain in its relentless pursuit of mining dominance. Nonetheless, a stunning reversal occurred as all of Bitmain's air-cooled miners, particularly the well-known Antminer S19 collection, had been compelled to stop operations in Texas. The official evaluation is obvious. Texas' excessive local weather situations, characterised by hovering warmth and oppressive humidity, are regarded as detrimental to the efficient functioning of air-cooled ant miners.
The upkeep woes of the Antminer S19 collection operated in Texas are dire. Models in optimum situation have a restore fee of 40%, whereas models in suboptimal situation have a restore fee of a staggering 100%. This led to the gradual removing of the Antminer S19 collection from Texas cabinets in mid-June of this 12 months, coinciding with a noticeable drop in network-wide hash charges round June sixteenth.
The core of the issue lies in extreme corrosion throughout the hashboard of the Antminer S19 collection, particularly the S19K Professional mannequin. The sharp distinction in colour between the air inlet facet and the remainder of the hashboard is a transparent manifestation of this corrosion, exacerbated by the tough Texas climate.
Upon nearer inspection, it turns into clear that this predicament isn’t just attributable to environmental elements, but additionally by an inherent design flaw in Bitmain's miners. The continued use of compact warmth sinks, whereas efficient at dissipating warmth, has confirmed to be a double-edged sword beneath sure situations.
Particularly, Bitmain's Antminer S19K Professional employs a warmth dissipation construction harking back to the double-sided compact radiator of Bitmain's Antminer S17, which seems to be very vulnerable to break beneath sure circumstances. These conditions embody:
First, transportation vulnerabilities:
Small radiators are delicate to vibrations and are due to this fact liable to changing into dislodged throughout transport, particularly in tough situations or improper packaging.
Second, speedy temperature fluctuations:
The small thermal capability exacerbates the consequences of speedy temperature modifications, as evidenced by the fluctuations in Bitmain Antminer S19K Professional's hash fee and the rise in energy ratio with rising ambient temperature. This may trigger injury even within the absence of utmost situations.
Third, chip breakage as a result of moisture:
After a number of days of shutdown, the restricted safety offered by the small radiator could make the chips extra vulnerable to moisture absorption and cracking upon restart.
In conclusion, Bitmain's Antminer S19 collection confronted formidable challenges within the harsh Texas local weather and uncovered the constraints of present design approaches. Because the mining trade continues to evolve, it's essential for Bitmain and different producers to adapt their designs to make sure reliability and longevity and stand up to the pains of quite a lot of environments within the fixed pursuit of mining superiority. It’s important to take action.
