Hello!
 
So I just received my x570 dark motherboard. It seems there is a cooling fan on the motherboard near the heatsink? It is extremely loud (more like a high-frequency pitch sound-like fan) under load. When CPU is over 70 degrees, it sounds like a jet engine. It is even louder than my case fans (Noctua A12 at 1500 rpm) ..... Is it normal? is it possible to turn off this cooling fan? 
 
edit: nevermind, was a noisy fan on my CPU cooler. 
Thanks!
