I’m using an ASUS ExpertBook B9 with an i7-1165G7, no dedicated GPU. I always need to switch to a performance profile in order to run games. This works fine on Windows 10 but when trying the performance power profile on an Ubuntu 24.04.3 live USB I do not hear any difference in fan speed, presumably because GNOME’s power profile feature doesn’t work with my hardware.
Is there any other way I can increase fan speed before playing games and then bring them back down to normal when I’m done gaming? I asked about this on Ubuntu’s forum but got no response.
Don’t worry about that, the OS does not need to control fan speeds, it’s built in to the hardware.
In the BIOS many computers will let you control the temperatures that determine the speed. Also you can use software to override the hardware defaults but it’s usually only really necessary if you want to tune it for extra quietness.
