Setup and Installation
Follow these steps for proper installation of your ID-COOLING FX240 LCD liquid cooler. Ensure your system is powered off and unplugged before proceeding.
1. Prepare the CPU Socket
Identify your CPU socket type (Intel or AMD) and select the corresponding mounting hardware. Install the backplate (if required for your socket) and standoffs onto the motherboard.
2. Apply Thermal Paste
Clean the CPU surface thoroughly. Apply a small amount of the provided FROST X45 thermal paste to the center of the CPU's integrated heat spreader (IHS). The thermal paste has a conductivity of 15.2W/M-K for optimal heat transfer.

ARGB Lighting Control
The ARGB lighting ring on the pump head and the fans can be synchronized and controlled via the ID-COOLING software or your motherboard's ARGB software (if compatible). This allows for various lighting effects and color schemes.
Maintenance
Regular maintenance ensures optimal performance and longevity of your liquid cooler.
- Dust Removal: Periodically clean dust from the radiator fins and fan blades using compressed air. Ensure fans are not spinning during cleaning.
- Fan Inspection: Check fan blades for any obstructions or damage. Ensure fans are securely mounted.
- Tubing Inspection: Inspect the tubing for any kinks, leaks, or damage. While the system is sealed, visual inspection is recommended.
- Cold Plate Contact: If CPU temperatures rise unexpectedly, re-check the mounting pressure of the cold plate on the CPU. Re-applying thermal paste may be necessary after several years of use.
Troubleshooting
This section addresses common issues you might encounter.
- No Power to Pump/Fans/LCD:
- Ensure all power cables (SATA power, fan headers, USB 2.0 header) are securely connected to the motherboard and power supply.
- High CPU Temperatures:
- Verify the pump is running (you may feel a slight vibration or hear a faint hum).
- Check fan operation; ensure they are spinning and not obstructed.
- Confirm the cold plate has proper contact with the CPU and thermal paste is adequately applied.
- Ensure radiator fins are not clogged with dust.
- LCD Screen Not Displaying/Software Issues:
- Ensure the USB 2.0 header cable is correctly connected to both the pump and the motherboard.
- Reinstall the ID-COOLING control software.
