Unwinder, the creator of MSI Afterburner, has released version 4.6.6 Beta 5, a significant update supporting Nvidia’s RTX 50 Blackwell GPUs and experimental compatibility with the latest Intel and AMD processors. While no specific date has been provided for a stable release, the updated beta version is available on Guru3D and will be downloadable from MSI’s official website after the Chinese New Year holidays.
MSI Afterburner, a popular overclocking utility that includes RivaTuner for hardware monitoring, now supports up to four independently controllable GPU fans, a step up from previous triple-fan support. This enhancement aligns with expectations that RTX 50 GPUs will include dedicated fan controllers for each fan, though Nvidia’s reference PCB design specifications remain unclear.
Another major addition is integrating Nvidia’s G-Assist AI feature, which will be released in February. This feature will allow users to leverage AI-assisted overclocking and system tuning within the software directly.
To enhance user experience, MSI Afterburner now defaults to the Windows 11 Dark skin, providing a seamless look that matches the operating system’s aesthetics. Notably, the newly introduced quad-fan control interface is only available in the Windows 11 dark and light skins, along with a newly designed MSI Special skin.
Additionally, RivaTuner has been updated to version 7.3.7 Beta 5, which introduces quad-fan monitoring support for RTX 50 GPUs and improves sensor compatibility with Intel’s Core Ultra 200S (Arrow Lake) and AMD’s Ryzen 9000 (Zen 5) CPUs. As this is a beta release, users should expect minor bugs and quirks, which are anticipated to be resolved before the final stable version.
