Hey guys I'm pretty new to fedora and Linux in general and I have a question:

In windows 10 you can set maximum cpu usage to any value ex: 96% rather than 100% using power management settings for my laptop

It runs a lot cooler and the fan runs a lot slower without hardly any performance loss

Can you mimic this in linux I haven't been able to find a solid answer?

  • nice : see $> man nice for syntax and explanations.
  • cpulimit : probably not yet installed. To install
    $> sudo dnf install cpulimit
    type $> cpulimit for syntax and explanations.

there is a simple way to limit the cpu usage using the terminal

fist install "cpulimit "using the command

# dnf install cpulimit

it should be simple and easy

then issue the command

$ cpulimit

the terminal will list your options, its simple and easy to deal with

you can also install htop which is a must have tool, its exactly the same as top but in a more "friendly' shape.

if you run htop as root you can control how Nice the process is and you can increase and decrease the "niceness" as it suits you better

i hope this helped wish you the best of lick

In addition two the other two (useful) answers, I want to mention a Gnome extension that I am using, called CPU Power Manager.

Easy to install, easy to use. Not sure that is what you are looking for...
