The process is very simple, does not require prior knowledge of choosing the right one and is sufficient to follow the steps to find the right model.
However, it is true that not all GPU models will have replacement fans, especially when we talk about old or very old graphics cards, especially since at that time the industry did not do business with this kind of product and that This was not introduced in the market.
The option is to know our graphics card model
First of all, the first thing we should have is the graphics card itself or its box. What we will be looking for is a specific GPU model and in particular its SKU.
This is the first step that on well-known and commercially available models will save us from dropping a graphics card even on a PC. The next step with this data is already known directly to Aliexpress and enter by searching (in our case and example) "Zotac GTX 1660 SUPER AMP 6 GB fans" or "zt-16620D-10M fans).
This is usually enough for fans to appear in this search, where as a rule we will have different vendors. If this does not happen or we do not find a specific model, we should return to the most complex action, namely removing the card and its fans.
As they are in hand, in the background, we will see a particular model, along with its voltage and amperage and its interaction with the GPU PCB.
A particular model for fans is a very good sign to get
There's nothing like knowing a specific model for followers to optimize your search. In our case and continuing with the previous example, our Zotac goes up two Apistek GA92A2H with 12v amv and 0,35 amps, these rules are PWM as we see in its connector.
As will the case for some of you, model or card SKU we weren't able to get fans, but with some kind of followers yes.
In fact, one of the retailers offers us the option to buy both, or one or the other, helping to make the most affordable purchase if we have a problem with one of them.
As you can see the process is simple, replacing it is usually less expensive (especially if you have problems with the fan) and prevents the GPU from sitting in a drawer due to a lack of warranty, thus giving it a longer life and saving us money that we can allocate to other GPU purchases.
Of course, when we make a decision not because of such a stupid violation and on the other hand something is common in the towers with a lot of dust inside.
