What to do if the video card coolers spin at 100% when the value is 25%?

Question

Windows

The video card (GTX 1060 3GB) worked fine, there were no crashes before or anything that could cause this problem.
At one point it was necessary to check the old video card (GT630). Checked. In the morning I decided to look at the temperature of the computer and I see that the video card has a high idle temperature (53 degrees). I decided to raise the temperature with "MSI AFTERBURNER".
As soon as I tried to do this, the two coolers started spinning at maximum. I decided to change back, but nothing happens.
What I tried to do The list goes in order:

1. Rebooted the computer
   
2. Reinstalled the program
   
3. Reinstalled firewood
   
4. Reinstalled windows (I did it for other reasons, but for this situation it is important)
   
5. Installed firewood and MSI
   
6. Changed the power cord
   

Nothing helped. Naturally, I googled before all these operations. They offered to clean it, because it is possible that this is due to dust. But I didn't really find anything. (The video card is clean.)
I thought about getting into the BIOS, but for me this is still an extreme measure. At least until I understand for sure that the problem may lie there.
Addition:

1. Gpu z, when I set the MSI speed to 50% (for example), shows the same value and the same when I do the opposite.
   

Answer 1

Oh, had exactly the same problem with the same graphics card, but with three fans.
The problem was in the wire in the system unit, which stalled one of the fans and the rest began to thresh at maximum.
Check.

Answer 2

Remove all the software for regulating coolers and remove the BIOS battery for 10-15 seconds (this should reset its settings (the computer is turned off at the same time)) then you go into the BIOS settings and look for temperature settings there, check them and what you need to google (I can’t say what precisely because the chance that we have the same bios is less than 1%), then download the malwarebytes antivirus and check the system (the MB miner picked it up (well, the chance is just super scanty)) then check the wiring, did you damage anything during the manipulations with video cards, check the video card itself for damage, if system measures did not help you, then the problem in the
PS BIOS hardware is not an extreme measure, any changes in it can be rolled back, so do not be afraid to experiment, if something is not clear, then ask
