5. Guia d'instal·lació
Before beginning, ensure your computer is powered off and unplugged. Refer to your motherboard and PC case manuals for specific instructions regarding component installation and clearances.
5.1. Prepareu la placa base
For Intel Sockets (LGA1700, 1200, 115X):
- Place the Intel backplate behind the motherboard, aligning the holes with the CPU socket mounting holes.
- Insert the appropriate standoffs through the motherboard from the front, screwing them into the backplate.
For Intel Sockets (LGA2011-3, 2066 - Square ILM):
- These sockets typically have integrated backplates. Screw the appropriate standoffs directly into the existing mounting holes around the CPU socket.
For AMD Sockets (AM5, AM4):
- Remove the plastic retention clips from the motherboard, but keep the original backplate.
- Screw the appropriate standoffs into the original AMD backplate's mounting holes.
5.2. Instal·leu el radiador i els ventiladors
The fans are pre-mounted on the radiator. Determine the optimal mounting location in your PC case (e.g., top, front) based on case compatibility and airflow strategy. Secure the radiator to the case using the provided screws.
5.3. Apply Thermal Compound and Install Pump
- Clean the CPU surface with an alcohol wipe to remove any dust or old thermal paste.
- Apply a small amount of the included ARCTIC MX-5 thermal compound to the center of the CPU's integrated heat spreader (IHS). A pea-sized dot is generally sufficient.
- Carefully place the pump/cold plate assembly onto the CPU, aligning the mounting holes with the installed standoffs.
- Secure the pump with the provided thumb screws or nuts, tightening them in a diagonal pattern until snug. Do not overtighten.

5.4. Cable Management and Connections
The Liquid Freezer II features integrated cable management, with PWM and A-RGB cables for the fans routed within the tubing sleeving. This minimizes visible cables.
- Connect the 4-pin PWM connector from the pump to your motherboard's CPU_FAN or AIO_PUMP header. This controls both the pump and fan speeds.
- Connect the 3-pin 5V A-RGB connector to your motherboard's addressable RGB header. Ensure correct pin alignment to prevent damage.
- Route any remaining cables neatly within your case to maintain good airflow and aesthetics.

6. Funcionament
Once installed, the ARCTIC Liquid Freezer II 420 A-RGB operates automatically based on your motherboard's fan control settings. The pump and fans are PWM-controlled, allowing for dynamic speed adjustments based on CPU temperature, optimizing for both cooling performance and noise levels.
- Control PWM: The cooler's pump and fans are controlled via a single PWM signal from your motherboard. You can configure fan curves in your motherboard's BIOS/UEFI settings or using compatible software to fine-tune performance.
- A-RGB Lighting: The A-RGB lighting can be synchronized with your motherboard's RGB software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, GIGABYTE RGB Fusion, ASRock Polychrome Sync) to customize lighting effects and colors.
7. Manteniment
Un manteniment regular ajuda a garantir un rendiment òptim i una llarga durada del refrigerador de líquid.
- Eliminació de pols: Netegeu periòdicament la pols de les aletes del radiador i de les pales del ventilador amb aire comprimit o un raspall suau. Assegureu-vos que els ventiladors no girin durant la neteja.
- Inspecció visual: Check tubing for any signs of wear, kinks, or leaks. Ensure all connections are secure.
- Pasta tèrmica: While not frequently required for AIOs, if you remove the cold plate for any reason, clean off old thermal paste and apply new thermal paste before reinstallation.
8. Solució De Problemes
If you encounter issues with your ARCTIC Liquid Freezer II 420 A-RGB, refer to the following common problems and solutions:
| Problema | Causa possible | Solució |
|---|---|---|
| Temperatures altes de la CPU | Improper cold plate contact, insufficient thermal paste, dust buildup on radiator, pump failure. | Re-seat cold plate, reapply thermal paste, clean radiator/fans, check pump connection. |
| Fans Not Spinning / RGB Not Lighting Up | Incorrect cable connection, disabled fan header in BIOS, software conflict. | Verify PWM and A-RGB connections, check BIOS settings, update motherboard RGB software. |
| Soroll inusual de la bomba/ventiladors | Air bubbles in loop (pump noise), fan obstruction, loose mounting. | Gently tilt case to dislodge air bubbles, check for cable obstruction, ensure secure mounting. |
| Leaking Coolant | Damaged tubing or fitting. | Immediately power off system. Contact ARCTIC support for assistance. |
