When to Stop a FurMark Stress Test
Quick answer
Stop for unexplained artifacts, black screens, repeated driver resets, cooling failure or temperature approaching the specific GPU manufacturer’s limit.
What symptoms mean I should stop FurMark immediately?
Stop for unexplained artifacts, black screens, repeated driver resets, cooling failure or temperature approaching the specific GPU manufacturer’s limit.
Prepare a controlled Windows test
FurMark is a deliberately demanding graphics workload and should not be treated as a routine background task. Make sure the computer has adequate cooling and normal airflow, close other graphics-heavy programs, and locate the manufacturer’s published operating limits for your exact graphics card. If a system already has cooling problems, do not begin the test.
Check the card’s thermal specifications before starting. Keep monitoring visible and remain at the computer. Begin with a modest preset and stop if temperatures rise without stabilizing.
Keep conditions consistent
If a test ends due to instability, record the symptoms and allow a normal cool-down. Restore stock settings and examine logs before choosing any safer follow-up.
For repeatable results, preserve the FurMark major version, graphics API, preset, resolution, anti-aliasing mode, driver version and Windows power configuration. Keep a record of whether the GPU started cool or had just completed another workload. Changing several of these at once makes a before-and-after comparison unreliable.
Understand the results
Longer or more severe testing is not automatically more informative. Do not bypass hardware protections.
Observe the trend of temperatures and clocks rather than one peak value. A completed run demonstrates how the particular device handled that particular test; it does not certify the GPU, power supply, memory or overall PC. If performance varies, compare readings from the same system and consider a second, less intense real-world workload.
Stop conditions and next steps
End the run immediately if cooling no longer appears effective, the screen displays corruption, the graphics driver repeatedly resets, Windows freezes, or temperatures approach the manufacturer’s stated limit. Do not disable thermal or electrical protections. Allow cooling time before troubleshooting and avoid repeating crashes just to reproduce a result.

Frequently asked questions
What symptoms mean I should stop FurMark immediately?
Stop for unexplained artifacts, black screens, repeated driver resets, cooling failure or temperature approaching the specific GPU manufacturer’s limit.
Does passing this test guarantee that my GPU is healthy?
No. A passing stress test cannot rule out problems under other APIs, games or application workloads. Combine supervised measurements with normal usage and hardware documentation.
Should I maximize the power limit to improve the result?
No. Follow the hardware manufacturer’s published limits and do not defeat safety protections to obtain a higher benchmark score.
