Question Uncontrollable fan speeds ?

Recently built a PC with solid specs and everything has been going smoothly, mostly the fact that I have been able to game with low fan noise and very good temps. However, today all of a sudden after loading up a game that I have been playing, my CPU fans ramp up to sound like a jet engine (70-80% power). The CPU temps are well below 50C and around the low 40s while i was gaming so it doesn’t make sense for them to ramp up this high 10 seconds into a game. I will also add I’ve been adjusting the fan curves in the BIOS but nothing is working. Any help is appreciated.
 
Full specs? Include all model numbers if possible.
i have a 360 mm aio with 3 cooler master pwm sickleflow 120 fans hooked up to the cpu fan header via a splitter cable. my other fans (corsair rs120) are hooked up to system fan headers as well via daisychaining. running an i7 12700k with an rx 9070xt. i think the noise is mainly coming from my radiator fans

Can you post a pic of the inside of your case so we can see the radiator location and orientation of it's fans and hoses, and the orientation and locations of the case fans?
