In their own words
CoreCtrl
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.
MSI Afterburner
MSI Afterburner is Windows software for tuning graphics cards and monitoring hardware in real time. Its controls cover GPU clock frequency, voltage, power limits and fan speed, and users can set fan curves and save tuning profiles. MSI says it works with graphics cards from all brands, not only its own. OC Scanner can find the highest stable overclock settings for a card. While gaming, an on-screen display can show live system performance information. The page also describes Predator, a separate recording tool for games or overclocking that supports H.264, WMV and AVI formats. MSI lists a free plan at free, with overclocking and undervolting, hardware monitoring, custom fan control and an on-screen display. There is no free trial. MSI lists versions 4.6.6 (Final) and 4.6.7 (Beta), both released in September 2026. It warns that phishing sites may steal data and identifies msi.com and Guru3D as the correct sites.
