How to Check a GPU Fan Curve with FurMark

Can FurMark help evaluate a GPU fan curve?

FurMark can demonstrate how cooling responds to load when fan RPM and temperature are monitored. It does not automatically tell you the best fan curve.

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.

Start with automatic fan control and a short supervised run. Note baseline temperature and fan speed, then watch whether speed increases as the GPU warms. End testing immediately if fans stop unexpectedly or temperature keeps rising.

Keep conditions consistent

Compare changes only at similar ambient temperature and case airflow. Aggressive manual curves can trade noise for cooling; do not bypass the card’s protective behavior.

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

A quiet fan at low temperature can be normal because many modern cards use a zero-RPM mode. Validate sensor readings against the card manual.

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

Can FurMark help evaluate a GPU fan curve?

FurMark can demonstrate how cooling responds to load when fan RPM and temperature are monitored. It does not automatically tell you the best fan curve.

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.
