GPU Thermal Stress

⚠️ SAFETY ADVISORY

This tool uses intensive WebGL shaders to maximize GPU clock usage. During operation, your fans may spin up and system responsiveness may decrease. **Monitor your temperatures** using external software. If your screen flickers or the browser crashes, restart your computer immediately.

How Does an Online GPU Stress Test Work?

Our online graphics card stress test runs custom **WebGL (Web Graphics Library)** fragment shaders directly in your browser. These shaders execute complex mathematical operations for every single pixel on the screen, forcing your GPU (Graphics Processing Unit) to work at maximum capacity to render the fluid thermal simulation.

What is a GPU Burn-In Test Used For?

Burn-in and stress tests are critical for:

• Testing Hardware Stability: Verifying if your graphics card can handle high workloads without crashing, thermal throttling, or displaying visual artifacts.
• Verifying Cooling Capacity: Checking how quickly your GPU temperatures rise and whether your computer's fans and thermal paste are dissipating heat effectively.

How to Safely Stress Test Your Graphics Card

• 1. Close Background Apps: Close heavy applications, web pages, or games to ensure your browser has direct access to system resources.
• 2. Monitor Thermals: Use hardware monitoring software (like MSI Afterburner, HWMonitor, or Task Manager) to keep track of your GPU core temperature.
• 3. Watch for Throttling: If temperatures exceed **85°C**, click "ABORT" to let your GPU cool down and prevent automatic hardware thermal throttling.
