How hot is too hot?

So I recently built my own PC! First time playing Java Minecraft. I understand its a bit CPU heavy, but how heavy?

I have a 5070Ti, R7 7800X3D, and 32gb of DDR5. I use an AIO with my cpu.

I have ran RLCraft, BetterMC, AllTheMods, etc. and my CPU is constantly reading 65°- 80°c. Sounds normal but thats much more hot then my CPU ever gets in any other game.

Ill run modded Skyrim (Nolvus) with 3,577 mods, and even it doesn’t run my CPU over 60°. Even heavily modded Ark: Ascended doesn’t run it that high, and its poorly optimized.

While my temps aren’t crazy high on Minecraft, is this normal? For it to drag my CPU as much as it does? Is it a modding issue?
