Fan allways spins loudly when under a bit of load with latest Firware

Since I upgraded my V54 to Release v3.0.1 - Nitropad T430/X230 T480/T480s V54/V56 nv41/ns50 · Nitrokey/heads · GitHub the fan spins to (ig 100%) if the cpu gets a little hot. So when I update my System etc.. This wasn’t like this before. I can’t find a fan option in the Firmware Interface. Am I missing something?
