Video Allegedly Shows Crypto Miners Jet Washing Nvidia RTX GPUs

The transition of the Ethereum blockchain from Proof of Work to Proof of Stake, commonly referred to as a merge, effectively meant that cryptocurrency mining using consumer graphics cards was no longer profitable. rice field. Gamers were looking forward to cheap new and used GPUs becoming the norm, according to a series of videos posted on Twitter by I_Leak_VN.

In the video above, it’s somewhat surprising to see alleged Vietnamese GPU miners nonchalantly jet cleaning multiple racks of powerful GPUs. His I_Leak_VN on Twitter shared a collection of these interesting videos today. Alongside the video was a repeated warning about buying a used graphics card.

A powerful jet from this kind of cleaning system prevents potential physical damage (who misses random surface mount resistance?) and water intrusion where it may not readily evaporate. can easily be caused. Also, be careful with the fan, as the thermal grease and lubricating grease may come off.

The water allegedly used for jet washing/bathing was not particularly “clean”. Deposits tend to remain on PCBs and can cause damage leading to short circuits and other electrical damage when power is applied to these products.

A third video from the same source shows immersion cleaning being used on some graphics card PCBs and I/O brackets in a bath of “ozone water” being agitated using an ultrasonic cleaner. you can see that Whether this is the second stage of “refurbishment”, cleaning of jet-washed cards, or reserved for old, dusty, or dirty cards is not discussed. It should be mentioned that there are experts and hobbyists who use the immersion method to clean component PCBs. household dishwasherThose familiar with this cleaning method are very careful with water and cleaning additives. Impurities and deposits left after cleaning (and prolonged drying) can adversely affect electronic integrity.

Summarizing the above, it seems that some expected second-hand “as good as new” graphics cards, or even some “refurbished” graphics cards, may be prone to failure. If the silicon and the components that support it haven’t been stressed to the brink of death during the mining of time, they get an extreme cleaning to try and make the box look fresh. When looking for GPU bargains, keep an eye out on eBay or your local equivalent. It seems particularly important to ensure that you receive a refund or exchange. A warranty from a reputable seller is also probably worth it.
