Liquid Cooler III Pro 420 A-RGB

The Arctic Liquid Freezer III Pro 420 A-RGB is a high-performance, highly compatible, all-in-one water cooler for CPUs, designed for superior cooling performance and future compatibility. Featuring a 420 mm radiator with an improved design that increases the cooling surface area, it ensures enhanced heat dissipation and a larger liquid volume for effective management of temperature spikes. Equipped with 3 P14 Pro A-RGB fans with addressable RGB lighting, it provides strong static pressure for optimal radiator airflow while maintaining quiet operation. The integrated 60 mm VRM fan offers additional cooling for motherboard components, enhancing overall system stability. The cooler supports a wide range of Intel and AMD sockets, including the latest Intel LGA1851 and AMD AM5, guaranteeing compatibility with current and upcoming CPUs.

Integrated VRM Fan

The PWM-controlled fans reduce the voltage regulator temperature, ensuring stable performance.

Mounting relocation for Intel and AMD

Moves the cold plate to the CPU hotspot for more efficient heat transfer.

Intel contact frame

Optimized contact pressure distribution for longer CPU lifespan and improved heat dissipation.

Integrated Cable Management

The fan cables integrated into the case simplify installation and minimize cable clutter.

The new fans of the P14 Pro

The P14 Pro unleashes all its capabilities: quieter and more powerful at low speeds, with greater performance reserves under load - for maximum cooling without compromise.

Premium-Class Cooler

The 38 mm radiator not only enhances heat dissipation, but also holds more liquid than conventional 27 mm radiators. This reduces heat buildup and ensures more efficient handling of sudden temperature changes.

Premium Tubes

Reinforced EPDM tube with braided lining for increased durability

Easy Installation

Pre-installed, pre-wired fans, easy placement, and a dynamic electronic manual.

Includes MX-6 Thermal Paste

Simply apply in a cross pattern - the water pump’s cold plate distributes the paste evenly

Two Control Options

With the splitter cable, the pump, VRM fan, and radiator fans can be controlled separately or synchronized via a single PWM signal with the all-in-one cable.

Features

  •  420 mm radiator with expanded surface for improved cooling performance.
  •  Triple P14 PRO fans with addressable RGB lighting for customizable aesthetics.
  •  Integrated 60 mm PWM VRM fan for additional cooling of motherboard components.
  •  Wide compatibility with Intel sockets (including LGA1851) and AMD (including AM5).
  •  Pre-installed fans and optimized cabling for easy installation.
  •  MX-6 thermal compound included for optimal heat transfer.
  •  Silent operation with efficient pump and low-noise fans.
  •  Standard 3-pin A-RGB headers for broad motherboard/software compatibility.

  • This review is about the colour: Black

    For gaming, it is preferred by many, especially for AMD Ryzen. There is a slight difficulty in installation with the base provided for AMD. Another issue is that you need to make sure you have the space to place it at the top of the case; even though I have a full tower, it was difficult and I had to make new holes to fit it, but it cools very well with temperatures not exceeding 65 degrees.
    On some motherboards, the heatsink for the M2 does not fit, but if you contact the company, they will send you a more compact one for free in a short period of time.
    Overall, very good performance and low price

    Very good cooling performance.
    In combination with the Be Quiet FX 900 + 3 fans at the bottom of the tower, the processor is in silent mode (water cooling/case) at 21 degrees idle and 58 during stress test/gaming without power or thermal throttling. (Intel 14700KF)
    Very easy to install.

    Although it is amazingly effective at cooling, I can't give it 5 stars because its installation was exhausting.

    The pump screws refused to catch onto the mounting brackets, even when I put all my body weight into bending them into place.

    Eventually, I had to unscrew the mounting brackets to loosen them, lightly screw in the pump, tighten the brackets, and then tighten the pump.

    It works amazingly on the 9950X3D.

    Powerful. On a Core Ultra 7 285kf it keeps it permanently below 70 degrees Celsius. For typical office work (with very low speed on the cooler fans to be completely silent) I am at 30 degrees Celsius 99% of the day.

  • The first AIO solution I use after years of using custom watercooling loops. I can say that it is quite high quality and performs like the custom solution, taking up less space and with a nice aesthetic result. Time will tell, but it has a 6-year warranty so I believe anyone who buys it is covered.
    The only negative thing that disappointed me was that the tube with the thermal paste (mx-6) was completely dried out.

    Refrigerator 420mm. Purchased for future investment in the computer. For the moment, I have it on a Ryzen 7 7800x3D. The temperature has never risen above 65 degrees C. This particular implementation has no LED and RGB, it is aimed at those who want a computer and not a Christmas tree. At 100 euros (approximately) it is a no brainer purchase.

    This review is about the colour: Black

    Very good liquid cooling, I was in a dilemma whether to switch from air cooling (NH-D15s) to the Arctic and in the end, I didn't regret it.
    Installed on a 9800x3d (with undervolt negative offset -20). In OCCT at a room temperature of 29 degrees Celsius, with the NH-D15s it exceeded 90 degrees.
    Now with a custom curve on the pump and fans so that the machine is a bit quieter, it doesn't exceed 86 (in OCCT).
    In-game it doesn't go over 55 (while before it reached close to 70).
    The case is the Light Base 900 fx, obviously before buying you should check if it fits.
    I hope it lasts long enough...
