I have an Asus ROG STRIX B550-A GAMING motherboard with AMD Ryzen™ 7 5800X3D and for processor cooling, Corsair h100i RGB Platinum SE white with another 4 Corsair LL120 White RGB on the case. I just installed it and my case fans runs to fast , it increase their speed at the same time as using the processor. The fans act as CPU fans although they are mounted directly on the motherboard on CHA FAN 1 and 2 headers . The other 2 fans from the processor heatsink that are connected to the pump and the pump connected to USB header on the motherboard , run just fine at low speed.
To mention that I updated the bios and it still shows over 4000 rpm in the bios fan profile.
