GPU load strange?

I have a question about my RTX 2080 S.

I recently assembled a PC, it went well for a while, from today the fans of the GPU were extremely loud / fast. I noticed that I have a GPU utilization in e.g. Minecraft 60% and in the Assassins Creed titles Origins or Odyssey strangely 100%. The temperature remains constant at 78 ° C

Would be nice if someone could help me

What does the fan control in the NVidia controll pannel say.

And don't think it has to run at 100% with Minecraft, it only works if everything is actually used and Minecraft is programmed as "garbage" and waits for many things that are then probably processed with the CPU.
