In their own words
ASUS GPU Tweak III
ASUS GPU Tweak III is free Windows software for adjusting parameters on NVIDIA and AMD desktop graphics cards, including overclocking, voltage, and fan control. OC Scanner automatically optimizes clock speeds for NVIDIA cards and saves a profile without overwriting driver data. The Voltage-Frequency Tuner manages the GPU boost curve through multiple input methods. Profile Connect can load linked overclock, fan-curve, and OSD settings when a selected application runs. Users can configure GPU fans and system fans connected to FanConnect headers with curves or fixed RPM settings. Monitoring includes fan RPM and system power metrics, system information over full-screen apps, and log export for analysis. A hardware plug-in adds real-time component statistics, while the OSD has adjustable display properties. ASUS lists Windows 10 and 11, 2 GB RAM, and 200 MB storage as minimum requirements for most versions. Power Detector+ compatibility is limited to specified ROG cards. The listed stable release is version 2.1.9.5, dated September 18, 2026.
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.
