Bitmain Antminer S19J Pro: What Went Wrong
Recently, there has been a story circulating in the crypto mining community about a Bitmain Antminer S19j Pro catching on fire. In this article, we will discuss what happened, the potential reasons behind the incident, and what we can learn from this experience.
A Quick Recap of the Incident
For those not familiar with the incident, the miner in question had its stock fans removed in an attempt to quiet down the ASIC miner. The miner was then placed in a crypto mining shed and set up with an intake and exhaust system that involved an air filter box, an AC Infinity inline fan, and various adapters to connect the fan to the front and back of the miner.
The AC Infinity inline fan produces 800 CFM (cubic feet per minute), which is actually 300 CFM more than the stock fans. When the miner was turned on, within two to three minutes, there was a popping sound, a burning smell, and visible flames at the back of the miner.
Fortunately, no one was injured, and the owner managed to shut everything down before the flames spread. The miner was not used again, and the owner decided to investigate the issue further.
Inspecting the Damaged Miner
Upon removing the casing and examining the internals of the Antminer S19j Pro, the owner discovered that the bottom of the ASIC was blackened and charred. One of the hash boards had significant burnt chips, while the other boards appeared to be untouched by the incident.
In addition, one of the heatsinks appeared to be loose and angling towards another heatsink. It is unclear if this was the root cause of the fire, but it is certainly an interesting point to consider.
AC Infinity Inline Fan: Pushing It Too Far?
It is possible that the higher CFM provided by the AC Infinity inline fan may have been a factor in the incident. The extra airflow from the fan may have contributed to increased temperatures within the ASIC, resulting in the eventual fire.
However, this is purely speculative, and it is difficult to determine with certainty if this was the main reason behind the fire.
Taking Precautions and Reactions
The owner of the damaged Antminer S19j Pro reached out to Wadom, where the miner was initially purchased. Wadom, a complete Bitcoin mining solutions provider and largest distributor of Bitcoin mining equipment in the United States, agreed to provide a replacement miner as well as a return shipping label for the damaged unit.
Wadom’s response demonstrates excellent customer service and support for the hobbyist miner community. However, it is important to remember that this incident could have had far more disastrous consequences, such as causing significant damage to the mining shed or the owner’s property.
Learning From This Experience
The takeaway from this incident should be that hobbyist miners need to exercise caution when modifying their mining setups. It is crucial to carefully consider the overall impact of any changes to a mining setup, whether it’s something as simple as replacing a fan or more complex modifications.
Additionally, staying vigilant and keeping a close eye on your mining equipment during operation is vital to prevent potential fires or other hazards. Reacting quickly in emergency situations, like the owner of the Antminer S19j Pro, can significantly minimize potential damages and protect both your equipment and property.
In conclusion, while these types of incidents are rare, they serve as a reminder to remain precautious and vigilant when it comes to crypto mining. By taking the necessary precautions, understanding the limitations of your setup, and responding quickly to any potential hazards, you can ensure the safety of both your equipment and the environment in which you operate.
