5.3. PWM Fan Control
The included fans feature PWM (Pulse Width Modulation) intelligent temperature control. This automatically adjusts fan speed based on CPU temperature, optimizing cooling performance and reducing noise without manual intervention.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your CPU cooler.
- Dust Removal: Periodically clean dust from the heatsink fins and fan blades using compressed air or a soft brush. Ensure fans are not spinning during cleaning.
- Fan Cleaning/Replacement: The fans can be easily removed from the heatsink for thorough cleaning or replacement, thanks to the SS2 fasteners and magnetic top cover.
- Thermal Paste: If reinstalling the cooler or replacing the CPU, clean off old thermal paste and apply a fresh layer.
7. Troubleshooting
If you encounter issues with your CPU cooler, consider the following:
- No Display/Incorrect Readings: Verify that the 9PIN USB cable is securely connected to both the digital display board and the motherboard. Ensure TRCC software is installed and running correctly.
- High CPU Temperatures: Check that the heatsink is properly mounted and making good contact with the CPU. Ensure thermal paste is correctly applied. Confirm fans are spinning and not obstructed. Verify fan cables are securely connected to the motherboard.
- Excessive Fan Noise: Ensure fans are securely mounted and free from obstructions. Check for dust buildup on fan blades or heatsink fins. The fans feature S-FDB bearings designed for quiet operation; if noise persists, inspect for damage.
- Installation Issues: Double-check compatibility with your CPU socket and memory clearance. Refer to the installation steps and your motherboard manual.
