The resale of components There’s nothing wrong. Sometimes, many users buy products at a good price from small stores or good individuals to make changes to our set up, also to replace parts that, otherwise, we would not find officially. However, with the constant and accelerated fall in the price of cryptocurrencies and the consequent increase in investment to mine, it is causing the second-hand market to be filled with graphics cards, even rigssecondhand.
As I said before, there is nothing wrong with buying from other individuals, but we are talking about a very difficult situation today, even tense, which benefits from 2 things: dire need to sell, and extremely affordable prices for graphics cards that make more than one dream of expanding their PC with the latest generation components. We are not going to reduce this article to the well-known popular saying “cheap is expensive”, but we are going to analyze what the risks are, including the truths and mythsto get one second hand gpu if it has been used for crypto mining.
Fans may be damaged
One very important thing must be taken into account and that is the usage rate of these components. Your everyday GPU or gaming not usually at 100% working 24 hours a day, not even having the PC plugged in all day. The software included in the cards causes the use of the fans to oscillate depending on the Workloadsomething that mining GPUs do not do.
These are in continuous operation and therefore their fans suffer much more. Its constant use causes electric motors and fan bearings to wear out over time. On the other hand, thermal paste can also lose its physical values, and this will imply a change that, although it is not difficult, does suppose a medium-short term hassle.
GPU flood is here.

Their transistors suffer greater thermal wear
Even so, this goes beyond cooling and, as the PCWorld medium advanced, a GPU in continuous use for mining can suffer from thermal acceleration.. This results in a forced detriment of performance by the GPU to cope with high temperatures, something that reduces performance and can even damage it.
A GPU is made of silicon, with lithographed transistors and other microscopic components. An electrical current passed through that silicon gradually changes the character and physical structures of these components; wears them down and eventually they fail. As TechRadar comments, “the more and/or more electrical current passes through a transistor, the faster its useful life decreases. This is basic electrical engineering.”
Yield is lost every year
When cryptocurrency mining saw a subtle decline in 2021, many GPU builders came out to say that we shouldn’t buy one of these cards due to the continued deterioration of this component. Palit, for example, shared last year that according to internal tests, performance looks depleted Around a 10% year after year after its first use outside of cryptomining.
True, but also not very successful. In fact, it’s a lottery which can even affect a GPU firsthand. Get a mining graphics card carries its risks and the deterioration is one that yes or yes you are going to suffer, but it is likely that it will reach such a dramatic point. If we look at Linus Tech, the YouTube channel did tests for months and concluded that it does affect performance, albeit slightly and mostly It depends on many factorsespecially the use that has been given previously.
Even so, it should be noted that we can’t trust either at 100% of Linus Tech, I explain. This channel did a continuous test of various GPUs already used for mining for several months, but, judging by what it says and its condition, it seems that they have been treated with a lot of pampering for a miner —I want to think— who knows what he’s doing, something we can’t say about everyone. It’s not derogatory, we don’t all use our systems in the same way and it shows once we sell it to others. In fact, the channel argues that “if you see a cheap mining GPU, YOLO (you only live once)”, and an outlay of money “to try” is not a tasteful dish for everyone.
Mining is not as hard as gaming, but it does make a dent
Perhaps you have never thought of it that way, but playing video games involves the consumption and expenditure of resources much higher than the mined. We are not talking about light or infrastructure, but about the capabilities of the GPU itself. Miners, as a general rule, do underclock of your cards and reduce consumption of energy looking for efficiency, something contrary to what the player is looking for, which is performance for performance’s sake.
A user can do underclock Y undervolt without problems, but you have to keep in mind one thing: the miners convert electricity into money, so these require a minimum and efficient consumption. It is, as the How to Geek portal advances, a “balancing act, to have the greatest power using less energy”. But does this mean that they work in a state of full parity? No, in fact, although in video games they are used in a more “extreme” way, we must not forget about continued use and changes in voltage.
Is there any magic formula to buy a mining GPU?
not unfortunately there isn’t. Again, I want to bring back the lottery argument. By not knowing how and for how long the previous user has used his GPU, it is an act of full trust in someone who, in most cases, we do not know. However, trusting is useless and you have to ask and physically check the component before paying. I know that it is difficult, sometimes impossible since we are talking about online sellers, but that evaluation can save you from trouble.

The question is, do I recommend buying a used GPU for mining? Nope. It’s simple, straightforward, and perhaps somewhat extreme, but we don’t always have the money to try our luck. Mining GPUs, and generally a second-hand electrical component, are more prone to failure. I myself bought a GPU — specifically an AMD RX 580 — second-hand. I trusted and it went well, but I also had the opportunity to physically check if it had been used for tasks outside the gaming.
