Question Uncontrollable fan speeds ?

[tofulion1]

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.

Also the way fans are connected.
