I posted because of fan noise, but it got quiet after I disconnected the fan power. AI is great.

‌I asked the AI what the fan model was, and since that same model was discontinued,
I asked it to recommend a compatible product, and it gave me some options.
Of course, I couldn't trust the AI blindly, so I checked the specs myself,
and they are indeed compatible.
It has become quite convenient.
The problem was that it was the rear fan of the case.
