CoreCtrl vs G-Helper

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.

G-Helper is a free, portable Windows control tool for Asus laptops and handhelds. It brings together performance, fan, GPU, battery, and RGB controls in a single executable that does not require installation. Performance modes are Silent, Balanced, and Turbo, with built-in fan curves; GPU modes are Eco, Standard, Ultimate, and Optimized. Dedicated GPU controls include core and memory clock offsets, GPU power, Dynamic Boost, and temperature limits. Automation can change performance mode, GPU mode, screen refresh rate, and keyboard-backlight timeout according to AC or battery power. An in-game overlay reports FPS, CPU and GPU temperatures, fan RPM, and power draw. Selected Asus mice, keyboards, and headsets can have lighting, bindings, equalizers, and battery settings. The app checks Asus for model-specific BIOS and driver updates and uses the Asus System Control Interface driver plus BIOS-stored operating modes. It requires the .NET 10 Desktop Runtime and that Asus driver. The desktop application says it does not collect or transmit personal data.
