4. Compatibilitat
4.1. CPU Socket Compatibility
- Intel: LGA1851, LGA1700
- AMD: AM5, AM4
4.2. Case and Motherboard Compatibility
The radiator dimensions are approximately 277mm (L) x 120mm (W) x 65.5mm (H, including fans). Ensure your PC case has sufficient clearance for a 240mm radiator with a thickness of 38mm, plus the fans.
Nota important: Oversized components, particularly coolers on the M.2_1 slot of certain motherboards, may interfere with the installation of the Liquid Freezer III. It is recommended to consult the ARCTIC official website for a detailed compatibility checker or refer to your motherboard's manual for clearance specifications.

5. Configuració i instal·lació
Before starting, ensure your system is powered off and unplugged. It is highly recommended to watch the official ARCTIC installation video (accessible via QR code on the product packaging) for a visual guide.
5.1. Preparing the CPU
- Netegeu bé la superfície de la CPU amb alcohol isopropílic per eliminar qualsevol pasta tèrmica antiga o residus.
- Apply a small amount of the provided thermal paste to the center of the CPU. A pea-sized dot is generally sufficient.
5.2. Installing Mounting Brackets
Select the appropriate mounting hardware for your CPU socket (Intel or AMD).
5.2.1. Intel LGA1851 / LGA1700 Installation
- Install the Intel contact frame onto your motherboard. This frame improves contact pressure distribution for more efficient heat transfer.
- Secure the backplate and standoffs according to the instructions for your specific socket.

5.2.2. AMD AM5 / AM4 Installation
- Utilize the native AMD offset mounting. This design optimizes coverage of the CPU hotspot for Ryzen processors, enhancing heat transfer efficiency.
- Attach the AMD mounting clips to the pump unit and secure them to the motherboard's stock backplate.

5.3. Mounting the Pump/Cold Plate
- Carefully place the pump/cold plate assembly onto the CPU, aligning it with the mounting brackets.
- Secure the pump unit using the provided screws, tightening them in a cross pattern until snug. Do not overtighten.
5.4. Muntatge del radiador i dels ventiladors
- Position the radiator in your desired mounting location within the PC case (e.g., top, front).
- Secure the radiator to the case using the appropriate screws.
- The fans are pre-installed on the radiator. Ensure their orientation is correct for optimal airflow (intake or exhaust, depending on your case's cooling strategy).
5.5. Cable Management and Connections
The Liquid Freezer III features integrated cable management, where the PWM cables of the radiator fans are routed within the hoses. This results in a single visible cable connection to the motherboard.
- Connect the main PWM connector from the cooler to your motherboard's CPU_FAN header.
- For A-RGB lighting, connect the A-RGB cable to a compatible 3-pin 5V A-RGB header on your motherboard.
- The cooler also includes a PWM-controlled VRM fan. This fan's cable is integrated and will draw power from the main PWM connection, providing active cooling to voltage regulator modules.

6. Funcionament
6.1. Fan and Pump Control
The Liquid Freezer III's pump and fans are PWM-controlled, allowing for dynamic speed adjustments based on CPU temperature. This can be configured through your motherboard's BIOS/UEFI settings or dedicated software provided by your motherboard manufacturer.
- Recomanat: Set a custom fan curve in your motherboard's BIOS to balance cooling performance and noise levels. Aggressive fan curves can lead to higher noise, while a more relaxed curve can reduce noise at the cost of slightly higher temperatures.
- The integrated VRM fan operates automatically based on the PWM signal, contributing to overall system stability by cooling critical motherboard components.
6.2. A-RGB Lighting Control
The A-RGB lighting on the fans and pump can be controlled via your motherboard's A-RGB software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, ASRock Polychrome Sync, Gigabyte RGB Fusion 2.0). Ensure the A-RGB cable is correctly connected to a compatible 3-pin 5V A-RGB header on your motherboard.

7. Manteniment
Regular maintenance helps ensure optimal performance and extends the lifespan of your cooler.
- Eliminació de pols: Netegeu periòdicament les aletes del radiador i les aspes del ventilador per evitar l'acumulació de pols, que pot impedir el flux d'aire i reduir l'eficiència de la refrigeració. Feu servir aire comprimit o un raspall suau.
- Inspecció del cable: Check all cables for secure connections and signs of wear.
- Nivell de líquid: The AIO unit is a closed loop system and does not require refilling. If you suspect a leak or significant performance drop, contact support.
8. Solució De Problemes
| Problema | Causa possible | Solució |
|---|---|---|
| Temperatures altes de la CPU | Improper thermal paste application, loose cold plate, dust buildup on radiator, incorrect fan orientation, pump failure. | Reapply thermal paste, ensure cold plate is securely mounted, clean radiator/fans, verify fan direction, check pump connection. |
| Soroll del ventilador excessiu | Aggressive fan curve settings, fan obstruction, faulty fan. | Adjust fan curve in BIOS, ensure no cables are hitting fans, replace faulty fan if necessary. |
| A-RGB Lighting Not Working | Incorrect cable connection, incompatible motherboard header, software issue. | Verify A-RGB cable is connected to a 3-pin 5V A-RGB header, check motherboard software settings, ensure motherboard header is enabled. |
| La nevera no encaixa | Case clearance issues, motherboard component interference. | Double-check case and motherboard compatibility before purchase. Refer to ARCTIC's compatibility checker. |
