3.2. Motherboard Preparation
- For AMD AM5/AM4: Remove the motherboard's plastic retention brackets around the CPU socket. Keep the original backplate.
- For Intel LGA 1851/1700: Use the provided Intel backplate. Adjust the mounting hole position on the backplate to match your CPU socket (e.g., 1700).
3.3. Waterblock Installation
- Install the appropriate standoffs onto the motherboard's CPU socket holes.
- Attach the correct mounting brackets (Intel or AMD) to the standoffs using the provided screws. Ensure they are finger-tight.
- Remove the protective sticker from the cold plate of the waterblock.
- Carefully place the waterblock onto the CPU, aligning the bracket nuts with the screws on the mounting brackets.
- Tighten the screws on the waterblock bracket in a diagonal pattern until secure, ensuring even mounting pressure.

4.2. Fan Speed Control (PWM)
The RS120 fans support PWM (Pulse Width Modulation) control, allowing for precise adjustment of fan speeds. This enables the system to automatically adapt fan speeds based on CPU temperature, optimizing for either quiet operation or maximum cooling performance.
5. Maintenance
Regular maintenance ensures optimal performance and longevity of your liquid CPU cooler.
- Radiator Cleaning: Periodically clean dust from the radiator fins using compressed air. Ensure the system is powered off before cleaning.
- Fan Cleaning: Gently wipe fan blades with a soft, dry cloth to remove dust buildup.
- Tubing Inspection: Check tubing for any signs of kinks, leaks, or damage.
- Coolant: The AIO cooler is a sealed unit and does not require coolant refills or maintenance.
6. Troubleshooting
- High CPU Temperatures:
- Ensure the waterblock is securely mounted to the CPU with adequate pressure.
- Verify that the pump power cable is correctly connected to the motherboard's AIO_PUMP or CPU_OPT header.
- Check fan connections and ensure they are spinning. Adjust fan curves in iCUE for higher performance if needed.
- Clean any dust buildup on the radiator fins.
- Fans Not Spinning or Loud:
- Confirm fan cables are properly connected to the splitter and the splitter to the CPU_FAN header.
- Check fan speed settings in iCUE. Adjust to a quieter profile if noise is an issue.
- Inspect fans for any obstructions.
- LCD Screen Not Displaying:
- Ensure the USB cable from the waterblock is securely connected to a USB 2.0 header on the motherboard.
- Verify iCUE software is installed and running.
- Check for any driver updates for the cooler or iCUE software.
