When I start Minecraft (1.14.4), the CPU usage in Task Manager always goes to 100% for a few seconds. And in general, my CPU fan is always quite loud with Minecraft. Although my CPU is actually not that bad: Intel Core i7-4790K (4 GHz).
I have already looked through autostart programs and sorted out unnecessary ones.
Someone propose solutions or need a new fan? Or do I just have to set up the computer again?
Yes and where exactly is the problem now? It's not uncommon now that the CPU load briefly increases when starting CPU-heavy applications.
The problem is that the CPU fan is still quite loud during the game. And that has not always been the case. I didn't notice it at all, but my father pointed it out to me.
Then maybe you should dust off your computer.
Then clean the fan, it is probably dusty.
i got the same problem and its not even letting me play the game
The 100% usage seems indeed to be a bug. I start the game and get 100% usage in the main menu? No, that's not how a programm should work. Even more odd. I join a MP server and the usage drops drastically and remains at 5% when i go back to the main menu.
