About MSI Afterburner

MSI Afterburner is the most popular and powerful free GPU overclocking and hardware monitoring utility in the world. For many years it has been the first choice for millions of gamers, overclockers, cryptocurrency miners, content creators and PC enthusiasts who want full control over their graphics card.

The program offers extremely detailed real-time monitoring of GPU temperature, fan speed, core and memory clock speeds, voltage, power consumption, usage percentage, frame rate and many other important parameters. It also includes the legendary RivaTuner Statistics Server (RTSS) — the best on-screen display tool that shows FPS, temperatures, load and other data directly in games.

In version 4.6.6 (May 2026), MSI Afterburner received major updates: improved support for the latest NVIDIA, AMD and Intel Arc graphics cards, more accurate sensor readings, enhanced fan curve editor, better voltage control and a cleaner modern interface while keeping the classic functionality that users love.

MSI Afterburner works perfectly with graphics cards from all manufacturers — NVIDIA GeForce, AMD Radeon and Intel Arc. It does not require an MSI motherboard and is not limited to MSI graphics cards, despite its name. The program is completely free, contains no ads, no telemetry and no forced registration.

Thanks to its stability, rich functionality and regular updates, MSI Afterburner remains the undisputed leader in the field of GPU monitoring and overclocking in 2026. It is used daily by both beginners who just want to monitor temperatures during games and professional overclockers who push their graphics cards to the limit.

One of the biggest advantages of MSI Afterburner is the combination of monitoring and overclocking in one program. You can safely increase core and memory clock speeds, adjust voltage, create custom fan curves and save everything into profiles that can be switched with a single click.
