MSI Kombustor is MSI’s burn-in benchmarking tool that’s designed to push your graphics card to its limits so you can identify overheating, crashes, or instability issues. Built on the FurMark engine, it supports OpenGL and Vulkan to run heavy, continuous workloads that push the GPU to maximum heat for accurate stress testing and stability checks.

The Kombustor MSI includes multiple test scenarios (over 15) that target different parts of your GPU hardware. They’re available in two modes: demo/stress test mode (runs until the user stops it) and benchmark mode (runs for 60 seconds and displays an MSI Kombustor score). The tool also includes artifact scanning to detect visual glitches. Alongside GPU testing, it includes a CPU burner that loads CPU threads to simulate full system load, mainly for combined stress testing and checking power and cooling balance (not for CPU stress testing). Real-time monitoring shows temperature, clock speeds, and usage. 

It is widely used with MSI Afterburner for GPU stability tests. The latest MSI Kombustor v4.1.36 supports NVIDIA GeForce, AMD Radeon, and Intel Arc GPUs. Want to see if your PC’s cooling can survive hours of maximum stress? Use Kombustor to test your GPU stability and check for crashes before you start gaming or rendering.
