- Ensure the USB 2.0 header cable from the pump is securely connected to your motherboard.
- Verify that the Nexlinq App is installed and running.
- Check for any driver conflicts or Windows updates that might affect USB device recognition.
- High CPU Temperatures:
- Confirm the pump is running (check pump speed in Nexlinq App or BIOS).
- Ensure fans are spinning and correctly oriented for airflow.
- Verify the pump/block is making proper contact with the CPU and thermal paste is correctly applied.
- Check for dust buildup on the radiator.
- Fans Not Spinning or D-RGB Not Working:
- Check all fan and D-RGB cable connections.
- Ensure the D-RGB cable is connected to a compatible header or controller.
- Verify fan speed settings in BIOS or through the Nexlinq App.
- Limited Data Displayed on LCD: The Nexlinq App currently supports display of CPU/GPU temperature, CPU/GPU fan speed, and pump speed. Additional data such as RAM usage or liquid temperature may be added in future software updates.
