Guia de configuració
Follow these steps for proper installation of your ARCTIC Liquid Freezer III Pro 420 A-RGB cooler. It is highly recommended to consult your motherboard and PC case manuals for specific instructions related to fan headers, mounting points, and clearance.
1. Prepareu el vostre sistema
- Apagueu l'ordinador i desconnecteu tots els cables.
- Open your PC case and remove any existing CPU cooler. Clean the CPU surface thoroughly to remove old thermal paste.
- Ensure your PC case has adequate clearance for the 420mm radiator (18.03 x 5.43 x 2.68 inches or 458 x 138 x 68 mm).
2. Install Mounting Hardware
The Liquid Freezer III Pro 420 A-RGB supports both AMD and Intel platforms. Use the appropriate mounting hardware for your CPU socket.
For Intel LGA1851/1700:
- Install the provided Intel contact frame onto your motherboard. This optimizes contact pressure for better thermal performance and CPU longevity.
- Secure the backplate and standoffs according to the instructions provided with the cooler.
For AMD AM5/AM4:
- Utilize the native offset mounting design. This shifts the cold plate center towards the CPU hotspot for more efficient heat transfer.
- Attach the appropriate AMD mounting brackets and secure the backplate and standoffs.

3. Mount the Radiator and Pump
- Carefully position the radiator in your chosen mounting location (e.g., top of the case). Secure it using the provided screws.
- Align the pump/cold plate assembly with the CPU and gently lower it onto the CPU, ensuring the pre-applied thermal paste makes full contact.
- Secure the pump/cold plate assembly to the mounting hardware using the provided screws. Tighten screws in a cross pattern until snug.
4. Connecteu els cables
The Liquid Freezer III features integrated cable management, simplifying connections.
- Connect the single All-In-One 4-pin PWM cable from the cooler to your motherboard's CPU_FAN or AIO_PUMP header. This cable controls the pump, radiator fans, and VRM fan.
- For A-RGB lighting, connect the A-RGB cable to a compatible 3-pin 5V A-RGB header on your motherboard.

Instruccions de funcionament
Fan and Pump Control (PWM)
The ARCTIC Liquid Freezer III Pro 420 A-RGB utilizes Pulse Width Modulation (PWM) for dynamic control of fan and pump speeds. This allows your motherboard to adjust cooling performance based on CPU temperature, optimizing for both cooling efficiency and noise levels.
- Configuració de la BIOS/UEFI: Access your motherboard's BIOS/UEFI settings to configure fan curves. It is recommended to set the CPU_FAN header to PWM mode and adjust the fan curve to your preference. A more aggressive curve will provide better cooling under load, while a less aggressive curve will result in quieter operation at lower temperatures.
- Integrated VRM Fan: The integrated VRM fan is also PWM-controlled and helps to cool the voltage regulator modules on your motherboard, ensuring stable performance, especially during overclocking.

A-RGB Lighting Control
The A-RGB fans and pump head feature individually addressable LEDs, allowing for customizable lighting effects.
- Programari de la placa base: Control the A-RGB lighting using your motherboard's RGB synchronization software (e.g., ASUS Aura Sync, GIGABYTE RGB Fusion, MSI Mystic Light Sync, ASRock Polychrome Sync). Ensure the A-RGB cable is connected to the correct 3-pin 5V A-RGB header.
- Third-Party Controllers: If your motherboard does not have a compatible A-RGB header, you may use a separate A-RGB controller (not included) to manage the lighting effects.

Manteniment
Regular maintenance ensures optimal performance and longevity of your Liquid Freezer III Pro 420 A-RGB cooler.
- Neteja de pols: Periodically clean dust from the radiator fins and fan blades using compressed air or a soft brush. Ensure fans are not spinning during cleaning to prevent damage.
- Pasta tèrmica: While the pre-applied thermal paste is high quality, consider reapplying fresh thermal paste if you ever remove the cold plate from the CPU for maintenance or upgrades.
- Liquid Loop: The liquid cooling loop is sealed and requires no refilling or maintenance. Do not attempt to open it.
Resolució de problemes
