Why does one cooler not work on the video card, and the other two do not slow down?

Question

Video cards

I have an Asus Strix 1080 Ti card lying idle. When you turn on the computer with it, it works fine. But when for some reason (default settings, or settings of your own temperature profile in a special program) you start to turn the coolers at least 1%, then the vidyuha two coolers unwind to the fullest and do not stop the speed even if you reset them in the program until you turn off the computer . Through experiments, I noticed that the impeller of a non-working fan bulged out a little ... when I pressed on it, it went inside and after restarting the computer, everything worked fine. But when an hour is running at full speed, I noticed that the impeller again goes to the floor a centimeter or less .... but this is enough for the glitches to start again. What could be the connection between the impeller that has left the coil and two coolers that do not stop? How can this impeller be re-fixed there securely, without going to the service? It seems that if you press it, there should be a click, but it doesn’t happen ..... Because of the quarantine, everything is closed .... repair is still possible only at home ..

PS: If this is important, then the first cooler, which comes from the wire that is connected to the power supply, has bugs ... and the last two coolers from the power circuit are buggy with speed

No way. If it comes out, then the paragraph has arrived. It's time to change coolers.
