The Ethereum blockchain changeover from Proof of Work to Proof of Stake, generally known as the Merge, successfully meant crypto coin mining with shopper graphics playing cards was no longer profitable. Whereas players appeared ahead to cheaper new and used GPUs changing into the norm, in response to a collection of movies posted to Twitter by I_Leak_VN, GPU crypto miners in Vietnam seem like jet washing gear their previous mining equipment earlier than placing the parts up on the market on eBay or native equivalents.
Some Vietnamese miners have cleaned up their previous graphics playing cards after ETH merge by bathing them with extraordinarily excessive danger. It is actually their cleansing season whereas ready for the following GPU-minable third coin. (1/3) pic.twitter.com/qnUMWxpyctSeptember 23, 2022
Within the video above it’s considerably startling to see what’s purportedly a Vietnamese GPU miner casually jet washing a number of racks full of highly effective GPUs. Twitter’s I_Leak_VN shared a set of those intriguing movies at the moment. Alongside the movies got here repeated warnings about shopping for used graphics playing cards.
The highly effective jets from this type of cleansing system can simply trigger potential bodily injury (who’d miss a random floor mount resistor?) or water ingress into locations it won’t simply evaporate from. Additionally, thermal paste or lubricating grease could presumably be eliminated too, so watch these followers.
The water allegedly getting used within the jet washing / bathing wasn’t notably “clear”. It may simply go away deposits behind on the PCB, doubtlessly inflicting injury that might result in quick circuits or different electrical injury as soon as these merchandise are powered up.
In a 3rd video from the identical supply, we will see immersion washing getting used on some graphics card PCBs and I/O brackets in a shower of ‘ozone water’ that’s being agitated utilizing an ultrasonic cleaner. Whether or not it is a second stage of ‘refurbishment’ or cleansing for the jet washed playing cards, or is reserved for older, dustier or grimier playing cards isn’t mentioned. We should point out that there are professionals and fans that often wash part PCBs through immersion strategies, and even in a household dishwasher. These nicely versed on this cleansing methodology are once more very cautious about their water and cleansing components; any impurities or deposits left behind after the wash (and prolonged drying) might be detrimental to digital integrity.
Summing up the above, it seems to be like a portion of the anticipated flood of used, ‘like new’ and even some ‘refurbished’ graphics playing cards might be susceptible to failure. If the silicon and supporting parts haven’t been pressured to inside an inch of dying throughout their time mining, they’re then subjected to excessive cleansing to attempt to make them look field contemporary. Watch out on the market on eBay or your native equal if you end up GPU bargain hunting. It seems to be like guaranteeing it is possible for you to to get refunds and/or replacements notably vital, and a assure from a vendor with an excellent fame would in all probability be worthwhile too.
