Texas, the main mining epicenter in the USA, has traditionally been a strategic cornerstone for Bitmain's relentless pursuit of mining dominance. Nevertheless, there was a shocking twist as all of Bitmain's air-cooled miners, particularly the celebrated Antminer S19 sequence, have been compelled to close down in Texas. The official evaluation is unequivocal: The intense weather conditions of Texas, characterised by intense warmth and oppressive humidity, are thought of unfavorable for the environment friendly operation of air-cooled antminers.
The upkeep challenge inside the Antminer S19 line working in Texas is critical. Models in optimum situation face a 40% restore price, whereas these in sub-optimal situation expertise a staggering 100% restore price. This led to the phasing out of the Antminer S19 sequence from Texas cabinets in mid-June of this 12 months, coinciding with a big drop within the community's total hashrate round June sixteenth.
On the core of this downside is extreme corrosion in Antminer S19 sequence hashboards, particularly the S19K Professional mannequin. The stark distinction in coloration between the air consumption aspect and the remainder of the hashboard is a tangible manifestation of this corrosion, exacerbated by the cruel Texas climate.
Upon nearer examination, it’s clear that this predicament stems not solely from environmental components, but additionally from Bitmain miners' personal design flaws. The continued use of compact heatsinks, whereas efficient for warmth dissipation, has confirmed to be a double-edged sword beneath sure situations.
Specifically, the Antminer S19K Professional Bitmain makes use of a warmth dissipation construction harking back to the double-sided small radiator Bitmain Antminer S17, which has confirmed to be extremely inclined to wreck beneath sure circumstances. These circumstances embrace:
First, the visitors vulnerabilities:
The small cooler's sensitivity to vibration makes it susceptible to slipping throughout delivery, particularly in bumpy situations or insufficient packaging.
Second, speedy temperature fluctuations:
As evidenced by Bitmain Antminer S19K Professional's fluctuating hashrate and elevated efficiency ratio with growing ambient temperature, its small thermal capability exacerbates the affect of speedy temperature modifications. This will result in harm even within the absence of maximum situations.
Third, moisture-induced chip cracking:
After shutdowns for a number of days, the restricted safety provided by the small heatsink leaves the chip inclined to moisture absorption, which may trigger cracking upon reboot.
In conclusion, Bitmain's Antminer S19 sequence met an enormous problem within the unforgiving local weather of Texas, exposing the restrictions of their present design method. Because the mining trade continues to evolve, it will likely be crucial for Bitmain and different producers to adapt their designs to resist the trials of assorted environments and guarantee reliability and longevity amid the relentless pursuit of mining dominance.
