Installation Tips for Optimal Performance
Proper installation is crucial for achieving the best cooling performance:
- Thermal Paste: Use a pea-sized amount in the center of the CPU. Too much paste can actually reduce performance.
- Mounting Pressure: Ensure even mounting pressure by tightening screws in a cross pattern gradually.
- Fan Orientation: For air coolers, ensure fans push air through the heatsink. For AIOs, mount the radiator with tubes at the bottom if possible.
- Case Airflow: Good case airflow is essential. Ensure intake fans bring cool air in and exhaust fans remove hot air.
- Fan Curves: Set appropriate fan curves in BIOS or software. Balance between cooling performance and noise levels.
