- The 38mm thick radiator holds more liquid than standard 27mm radiators, improving heat dissipation and handling temperature spikes.
Cons
- Radiator fans can produce significant noise, reaching up to 59-62 dBA at maximum speeds.
- The Intel mounting solution, which replaces the stock ILM with a contact frame, can be more complex for new builders.
- Some users report stiff tubing, which can make routing challenging in smaller cases.
- The cooler lacks a dedicated coolant temperature sensor, potentially leading to fan speed fluctuations based on CPU temperature spikes.
- The pump can be noticeably loud for some users, even when not at maximum RPM.
Dimension Scores
The 38mm radiator, P12 Pro fans with 77 CFM airflow and 6.9 mmH2O static pressure, and integrated VRM fan provide exceptional thermal performance, especially on high-TDP CPUs.
While quiet at low speeds, the P12 Pro fans can reach up to 62 dBA at maximum RPM, and some users report noticeable pump noise.
Features a copper cold plate, aluminum radiator, reinforced EPDM tubing, and a 6-year warranty, indicating a durable construction.
Integrated cable management routes fan PWM cables through the tubing sleeves, simplifying the appearance, though individual fan cables are short.
Best For
- Overclocked Intel LGA1700/1851 or AMD AM5/AM4 systems needing top-tier thermal management.
- PC builds where VRM cooling is a priority due to high-power draw CPUs.
- Users who prioritize maximum cooling performance and are comfortable with potentially higher noise levels under extreme load.
Not Recommended For
- Silence-focused builds where any fan or pump noise is unacceptable.
- Novice builders looking for the simplest possible installation process, especially on Intel platforms.
- Compact ITX cases that may struggle with the 38mm thick radiator and stiff tubing.
Watch Out For
- The P12 Pro fans can generate up to 62 dBA at full speed, which is significantly louder than many other AIOs.
- Intel LGA1700/1851 installation requires removing the stock ILM and installing a contact frame, which some users find daunting.
- Some users reported CPU temperatures around 80-90°C even with fans at 3000 RPM while gaming, suggesting potential mounting or case airflow issues.
- The pump has been reported by some users to be 'super loud', impacting overall system acoustics.
- Fan cables are short despite integrated management, which can limit routing flexibility in certain case configurations.

What Buyers Say
Many users highlight the cooler's ability to tame even the hottest CPUs, with some noting significant temperature drops compared to previous coolers. The integrated VRM fan is frequently praised for its effectiveness in cooling motherboard components. However, the trade-off for this performance is often noise, with several reports of the fans becoming very loud at higher RPMs, and some users experiencing noticeable pump noise. The Intel contact frame, while beneficial for performance, adds a layer of complexity to the installation process that some find challenging.
“Man, this thing cools my 13900K like a champ, but holy cow, when those fans ramp up it sounds like a jet taking off. My VRMs are chill though, so I guess it's a trade-off.”
Common Praise
- Keeps CPU temperatures significantly lower than other coolers, even with demanding workloads.
- The VRM fan effectively cools the voltage regulators, preventing thermal throttling in that area.
- Pre-installed fans and integrated cable routing make the initial setup visually clean.
- The included Intel contact frame improves CPU-to-cold plate contact for better heat transfer.
Common Complaints
- Radiator fans are very loud when spinning at higher RPMs, sometimes reaching 60 dBA+.
- The pump can produce a 'super loud' noise for some users.
- Intel installation process is more involved due to the contact frame, requiring removal of the stock ILM.
- Lack of a coolant temperature sensor causes fan speeds to fluctuate aggressively based on CPU temperature spikes.
Ownership Tips
- You might need to adjust fan curves manually to balance cooling performance with acceptable noise levels.
- The stiff tubing can make routing tricky, so plan your tube runs carefully before installation.
- Ensure your case has adequate clearance for the 38mm thick radiator, as it's chunkier than many standard AIOs.
- If installing on Intel, be prepared for a slightly more involved process with the contact frame; watch an installation guide first.
Frequently Asked Questions
Is this cooler compatible with Intel LGA1200 sockets?
No, this cooler is specifically designed for Intel LGA1700 and LGA1851 sockets, and AMD AM4 and AM5 sockets. It is not compatible with LGA115x/1200 sockets out of the box.
Does the cooler come with thermal paste?
Yes, Arctic includes a tube of MX-6 thermal paste with the Liquid Freezer III Pro 360 A-RGB.
Can I control the pump and fans separately?
Yes, the cooler provides two control options: a single cable to synchronize all components or a splitter cable for independent control of the pump, VRM fan, and radiator fans.
What are the dimensions of the radiator?
The radiator measures 398mm in length, 120mm in width, and 38mm in height.
Is the installation difficult?
Installation on AMD AM5 is generally straightforward. For Intel LGA1700/1851, it involves replacing the stock ILM with an included contact frame, which can be more involved than traditional mounting.
Buying Guide
When looking at an AIO CPU cooler like this, you're essentially buying a self-contained liquid cooling loop. It's designed to move heat away from your CPU more effectively than air coolers, especially for high-performance processors. The size of the radiator (360mm here) and its thickness (38mm) directly impact how much heat it can dissipate. More surface area and liquid volume generally mean better cooling. The fans are also critical; their speed, airflow (CFM), and static pressure (mmH2O) determine how well they push air through the radiator fins.
Radiator Size (360mm) & Thickness (38mm)
Think of the radiator as the car's radiator – it's where the heat from the engine (your CPU) gets released into the air. A 360mm radiator means it holds three 120mm fans. The 38mm thickness means it has more surface area and liquid capacity than a standard 27mm radiator, allowing it to shed more heat.
P12 Pro Fan Airflow (77 CFM) & Static Pressure (6.9 mmH2O)
Airflow (CFM) tells you how much air the fan can move, like how much wind a fan creates. Static pressure (mmH2O) is how well the fan can push air through resistance, like the dense fins of a radiator. High static pressure is crucial for AIOs because the fans need to force air through those tight spaces to cool the liquid effectively.
Integrated VRM Fan
Your CPU isn't the only hot component; the Voltage Regulator Modules (VRMs) on your motherboard also get toasty, especially with powerful CPUs. This small fan on the pump block blows air directly onto them, helping to keep them cool and stable, which can prevent system instability or throttling.
Alternatives
If this cooler doesn't fit your needs, look for AIOs with larger radiator sizes (e.g., 420mm) for even greater cooling capacity, or models with lower maximum fan RPMs and different fan designs if noise is a primary concern.
