Maintenance
Regular maintenance helps ensure optimal performance and extends the lifespan of your graphics card.
- Dust Removal: Periodically clean dust from the fans and heatsink using compressed air. Ensure the system is powered off and unplugged before cleaning. Hold the fan blades gently to prevent them from spinning rapidly during cleaning, which can damage the bearings.
- Environmental Conditions: Operate the graphics card in a well-ventilated environment. Avoid extreme temperatures and high humidity.
- Driver Updates: Keep your graphics drivers updated to the latest stable version provided by AMD or PowerColor to benefit from performance improvements and bug fixes.
