CoreCtrl vs Notebook FanControl

CoreCtrl is a free, open-source GNU/Linux application for controlling hardware through profiles. Profiles can launch when an associated Linux or Windows application starts, then restore their settings when it ends. You can also activate a manual profile, which takes priority over automatic profiles; only one manual profile can be active at a time. The project describes its AMD GPU controls as full, covering fans, frequency, power, sensors, and hardware and software information. CPU support is more limited: it includes a frequency-scaling governor control, a package maximum-frequency sensor, and CPU package information. Automatic profiles need an executable binary name, so they cannot be tied to scripts or interpreted-language applications. The available controls depend on the Linux kernel version and hardware. Full AMD GPU control with the amdgpu driver requires a boot parameter and reboot. CoreCtrl is free, with no paid plans stated, and the project recommends installation through a distribution package manager. It is in maintenance mode, with development focused on fixes and upkeep rather than new features or hardware support.

Notebook FanControl (NBFC) is a free, open-source service for controlling notebook fans on Windows and Linux. Its configuration system adapts the service to many notebook models. Windows users run an installer, choose a notebook configuration, and apply it so NBFC can control the fans. Linux users build the software themselves, install its systemd service, and apply a notebook configuration; the project provides no pre-built Linux releases. Downloads are linked through GitHub releases and a Chocolatey package. The repository includes the GNU General Public License version 3. An FAQ points to a supported-notebook list and says a configuration for a similar model may work when yours is absent. The maintainer does not create individual configurations, so users may need to make one themselves. Some systems have conflicts with ImDisk Toolkit or HWiNFO. Nvidia Optimus notebooks may lose fan control while the dedicated GPU is active, and Linux Secure Boot can require disabling.
