All CPUs since Pentium 4/Athlon (down)clock themselves. iirc since Nehalem/Bulldozer they overclock themselves as compute demand increases. So totally normal behaviour.
Turtvaiz
Task manager frequency is basically never correct btw
AMD CPUs also opportunistically boost their clock frequencies. 3.9 GHz is only the base when turbo is off and the absolute worst case scenario.

No, that’s the normal boosting behavior
