Inadequate speed of the video card fans.

Greetings. In general, the problem is in the title. During any short-term load (opening a browser, watching a video, downloading something), the cooler begins to howl frantically for a short period of time (1-2 seconds), while GPU-Z shows that either the RPM is at 0, or at all at 100,000 RPM, which is naturally impossible. The temperature of the video card at these moments is within normal limits. During the game, this problem is not observed. I make the assumption that the coolers start to roar when the frequency is jumped, therefore they do not make noise in the game (although at the moment I am writing this, the coolers still howl, although the frequency does not change at all). I exposed all curves through MSI afterburner, fans completely ignore it. Previously, this feature disappeared during a reboot (then msi began to work), but now it does not help anymore. What could it be? Not really a tachometer blade? Maybe the problem is in the connector?
