4. Installation Guide
This section details the installation process for your Thermalright Aqua Elite 240 ARGB CPU Water Cooler. Please follow the steps carefully for your specific CPU socket type.
4.1. General Preparation
- Ensure your computer is powered off and unplugged.
- Open your PC case and locate the CPU socket area on your motherboard.
- Remove any existing CPU cooler. Clean the CPU surface thoroughly to remove old thermal paste.
4.2. AMD AM4/AM5 Installation
- Remove the protective sticker from the coldplate of the water block.
- Align the arrow on the AMD bracket with the arrow on the water block and rotate to install the AMD bracket onto the water block.
- Apply thermal compound to the CPU Integrated Heat Spreader (IHS).
- Place the water block onto the CPU. Use the buckles on the AMD bracket to secure the water block to the motherboard's existing retention module.
- Tighten both screws on the bracket with a screwdriver to apply mounting pressure evenly.

4.3. Intel LGA1700 Installation
- Adjust the mounting hole position on the Intel backplate to "1700".
- Install the backplate from the backside of the motherboard, ensuring the screws pass through the mounting holes.
- Install the 1700 standoffs onto the backplate screws from the front side of the motherboard.
- Remove the protective sticker from the coldplate of the water block.
- Align the arrow on the Intel bracket to the water block and rotate to lock it in place.
- Apply thermal compound to the CPU Integrated Heat Spreader (IHS).
- Align the mounting holes on the bracket with the standoffs and install the water block.
- Secure the metal brackets and water block with the four nuts, applying appropriate mounting pressure.

4.4. Wiring Connections
- Connect the pump power cable to the CPU_OPT or AIO_PUMP header on your motherboard.
- Connect the fan PWM cables to the fan splitter cable for synchronized fan speed control.
- Connect the PWM splitter cable to the motherboard's CPU_FAN socket to power the fans.
- Remove the protective caps from the ARGB 3-pin connectors.
- Connect the fan ARGB cables to sync the lighting signal.
- Connect the ARGB lighting cable to the motherboard's 3-pin +5V ARGB socket for lighting control.

5. Operating Instructions
Once installed, the Thermalright Aqua Elite 240 ARGB CPU Water Cooler operates automatically based on your motherboard's settings.
- Fan Control: The PWM fans will adjust their speed automatically via the motherboard's 4-pin PWM header based on CPU temperature. You can configure fan curves in your motherboard's BIOS/UEFI settings or through compatible software.
- ARGB Lighting: The addressable RGB lighting on the fans and water block can be controlled via your motherboard's 5V 3-pin ARGB header. Use your motherboard's RGB synchronization software (e.g., ASUS Aura Sync, MSI Mystic Light, Gigabyte RGB Fusion, ASRock Polychrome Sync) to customize lighting effects. Ensure your motherboard supports 5V 3-pin ARGB; this cooler is not compatible with 12V 4-pin RGB headers.
- Pump Operation: The water pump operates continuously to circulate coolant. Ensure the pump power cable is securely connected to a dedicated AIO_PUMP or CPU_OPT header for stable operation.

6. Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your liquid cooler.
- Dust Cleaning: Periodically clean dust from the radiator fins and fan blades using compressed air. Ensure fans are not spinning during cleaning to prevent damage.
- Tube Inspection: Check the water tubes for any signs of kinks, damage, or leaks. While the polymer compilation protection water pipes are designed for low evaporation and high life, regular visual inspection is recommended.
- Thermal Paste: Re-applying thermal paste is generally not required unless the cooler is removed. If re-installation is necessary, clean off old thermal paste and apply new compound.
7. Troubleshooting
If you encounter issues with your Thermalright Aqua Elite 240 ARGB CPU Water Cooler, refer to the following common troubleshooting steps:
- No Power/Fans Not Spinning:
- Check all power connections, especially the pump power cable to the motherboard's AIO_PUMP/CPU_OPT header and the fan splitter cable to the CPU_FAN header.
- Ensure the cables are fully seated.
- Verify fan settings in BIOS/UEFI are not set to "0 RPM" or a very low threshold.
- No ARGB Lighting:
- Confirm the ARGB 3-pin cable is correctly connected to a +5V ARGB header on your motherboard.
- Ensure your motherboard's RGB software is installed and configured correctly.
- Verify that the ARGB header is enabled in your motherboard's BIOS/UEFI.
- Remember, this cooler supports 5V 3-pin ARGB only, not 12V 4-pin RGB.
- High CPU Temperatures:
- Check if the water block is securely mounted to the CPU with adequate pressure.
- Ensure thermal paste was applied correctly and evenly.
- Verify that the pump is running (you might hear a faint hum or feel vibrations).
- Check fan orientation on the radiator for proper airflow (intake or exhaust, depending on case setup).
- Clean any dust buildup on the radiator fins.
