- The ETH shift from Proof of Work to Proof of Stake is specified as the Merge, which meant crypto coin mining using consumer graphics cards was not beneficial anymore.
- Although, gamers anticipated cost-effective new and used GPUs becoming the benchmark, as per some videos posted by I_Leak_VN on Twitter.
GPU crypto miners were seen jet-washing and cleaning their old mining kit in Vietnam prior to putting the parts for sale on eBay, a C2C and B2C sales platform.
In the video posted on Twitter, it can be seen that a GPU miner is randomly jet-washing various racks loaded with strong GPUs. Next to this, the videos came with continuous warnings concerning the purchase of used graphics cards.
The strong jets from such a cleaning system can simply cause potential physical damage or water entrance into places from where it won’t vaporize comfortably.
The water which is being used in the process was also not that clean. It can simply leave residuals on the PCB, eventually causing harm that may lead to short circuits and many more once the product is turned on.
We can also witness that immersion washing is being done with a few graphics card PCBs and I/O brackets in a shower of ‘ozone water’ that is being stirred with an ultrasonic cleaner. We should also mention that there are many experts and passionate that sometimes wash component PCBs by immersion methods, sometimes in a household dishwasher also.
Those professionals in this process are very careful about the water and cleaning equipment they use; any residual left after the wash may cause harm to electronic morality.
Conclusion
Concluding, it seems like a part of the anticipated flood of used, ‘such as new’ or few renovated graphics cards can be exposed to failure. If the silicon and backing parts have not been stretched to within an inch of death at the time of mining, they are then exposed to extreme cleaning to make them look fresh.
It would be best if you were very careful while looking on eBay or your native equivalent at the time of GPU bargain search. It seems like making you sure will make getting refunds and replacements specifically significant, and a promise from a seller with good recognition will likely be worthy too.
