2. Install Red Standoffs: Install four red standoffs into the motherboard's mounting holes.
3. Install Metal Brackets: Place two metal brackets onto the red standoffs and secure them with screws using a screwdriver.

4.2. Intel LGA115X/1200 Motherboard Installation

1. Assemble Intel Backplate: Use the inner mounting holes on the Intel backplate. Attach the blue washers to fix the backplate screws.
2. Install Backplate: Install the assembled Intel backplate from the back side of the motherboard, ensuring the backplate screws pass through the motherboard mounting holes.
3. Install Blue Standoffs: Install four blue standoffs onto the backplate screws.
4. Install Intel Brackets: Place two Intel brackets onto the standoffs.
5. Secure Brackets: Secure the brackets with nuts.

4.3. Intel LGA1700 Motherboard Installation

1. Assemble Intel Backplate: Use the outer mounting holes on the Intel backplate. Attach the blue washers to fix the backplate screws.
2. Install Backplate: Install the assembled Intel backplate from the back side of the motherboard, ensuring the backplate screws pass through the motherboard mounting holes.
3. Install Blue Standoffs: Install four blue standoffs onto the backplate screws.
4. Install Intel Brackets: Place two Intel brackets onto the standoffs.
5. Secure Brackets: Secure the brackets with nuts.

4.4. Common Procedures (All Sockets)

1. Apply Thermal Compound: Apply a small amount of thermal compound to the center of the CPU's Integrated Heat Spreader (IHS).

2. Remove Coldplate Protective Sticker: Carefully peel off the protective sticker from the waterblock's coldplate.
3. Mount Waterblock: Place the waterblock onto the CPU, aligning the waterblock bracket nuts with the screws on the installed Intel or AMD brackets.
4. Secure Waterblock: Tighten the nuts to secure the waterblock evenly.
5. Install Radiator: Install the radiator onto your PC case using the provided short screws. Ensure proper airflow direction.

6. Connect Fan PWM Headers: Connect the 4-pin PWM headers from the fans to the included fan hub.
7. Connect Fan Hub to Motherboard: Connect the fan hub to the motherboard's CPU_FAN socket.
8. Connect Waterblock PWM Header: Connect the waterblock's 4-pin PWM header to the motherboard's CPU_OPT or WATER_PUMP socket to power the water pump.
9. Connect ARGB Headers: Connect the fan 3-pin ARGB headers to sync lighting effects. Then, connect the 3-pin ARGB header from the fan hub to the motherboard's +5V ARGB lighting socket.

5. Operation

Once installed, the Thermalright Frozen Prism 240 operates automatically. The PWM fans and pump adjust their speeds based on CPU temperature, ensuring optimal cooling performance and noise levels.

• Initial Boot: Upon the first boot after installation, monitor your CPU temperatures using motherboard software or third-party tools to ensure proper function.
• Fan Control: Fan speeds are controlled via the motherboard's CPU_FAN header. You can typically adjust fan curves in your motherboard's BIOS/UEFI settings or through manufacturer-provided software.
• Pump Control: The pump speed is controlled via the CPU_OPT or WATER_PUMP header. It is generally recommended to run the pump at or near 100% speed for consistent performance.
• RGB Lighting: The Addressable RGB (ARGB) lighting on the waterblock and fans can be synchronized with compatible motherboard software (e.g., ASUS Aura Sync, MSI Mystic Light, Gigabyte RGB Fusion, ASRock Polychrome Sync) via the +5V ARGB header.

6. Maintenance

Regular maintenance helps ensure the longevity and optimal performance of your liquid CPU cooler.

• Dust Cleaning: Periodically clean dust from the radiator fins and fan blades using compressed air or a soft brush. Ensure fans are not spinning during cleaning.
• Inspect Tubing: Check the tubing for any signs of kinks, leaks, or damage.
• Monitor Temperatures: Regularly monitor CPU temperatures to detect any potential cooling issues early.
• Thermal Paste: While not frequently required, if you ever remove the waterblock, reapply fresh thermal paste before reinstallation.

7. Troubleshooting

If you encounter issues with your Thermalright Frozen Prism 240, refer to the following common troubleshooting steps:

• High CPU Temperatures:
  • Ensure the waterblock is securely mounted and making good contact with the CPU.
  • Verify that thermal paste was applied correctly.
  • Check if the fans are spinning and the pump is operating (you might hear a faint hum or feel vibrations in the tubes).
  • Ensure adequate airflow in your PC case.
• Fans Not Spinning / RGB Not Working:
  • Check all fan and ARGB cable connections to the fan hub and motherboard.
  • Ensure the fan hub is powered correctly.
  • Verify motherboard BIOS/UEFI settings for fan control and RGB lighting.
• Unusual Noise:
  • Check for loose fan screws or cables obstructing fan blades.
  • A slight gurgling sound initially is normal as air bubbles clear from the loop. If persistent, ensure the radiator is mounted higher than the pump.
