Review: Great performance, extremely quiet, great price. - - Effortlessly cools my Ryzen 9 5900x w/ PBO limits @ 200/185/130 - Idles at 40c , maxes out at 85c. For these power limits, that's impressive. - Extremely quiet... I actually had to look in the case to make sure the fans were spinning. Yeah, it's that quiet. Even when it's running max speed. Unreal! -It comes nicely cable managed and you can choose between 1 connection on the board or 3 in case you want to control the fans, pump and VRM fan separately. The VRM fan is a nice touch - keeping your VRMs cool can prevent little drops in voltage which in theory will keep your CPUs boost behavior more consistent. - Installation went okay, just make sure you have clearance. For what this is, I can't believe the price. I am very happy with my purchase. Just make sure you have a ginormous case with explicit 420mm radiator compatibility and enough verticality over the motherboard (if you are top mounting) to make room for the thick radiator on this thing. I even had some clearance issues (8-pin power for the VRM blocked the radiator) in my Thermaltake View 71 TG RGB. Had to get a little... creative. Another thing to bear in mind - that VRM fan that magnets to the pump/block - the blades visible from the front do not spin. Those just light up. The actual VRM fan is on that same part, but below and tucked away. Really, the only thing I can criticize is the length of the header cables... if they were longer you could more easily cable manage them.
Review: Great performance and a fan near the cpu socket, nice touch - After running a 360mm EK AIO for a while, I decided to upgrade to the ARCTIC Liquid Freezer II 420 A-RGB — not because of thermal issues, but to improve airflow throughout my HAVN case. I wanted all fans to be 140mm for consistency, better aesthetics, and improved internal airflow. Why I Chose This Cooler The standout feature for me was the small VRM fan built into the pump cap. It’s a thoughtful design — that small fan helps circulate air around critical components like the VRMs, RAM, GPU, and NVMe drives. In a tightly packed system, that airflow matters more than people give it credit for. Real-World Performance I was especially curious to see how it would perform with higher power BIOS settings, which used to push my EK 360mm into thermal throttling. The difference was immediate: • The 360mm would quickly throttle under high load, catch up, then throttle again. • The 420mm kept up from the start — no thermal throttling, even under sustained high-power workloads. Under long-duration CPU stress, the ARCTIC 420mm still ran about 3°C cooler than the 360mm. That part I expected. What I didn’t expect was how much better it handled rapid temperature fluctuations — scenarios where the system goes from idle to load instantly. The ARCTIC simply reacted faster and more effectively. Final Thoughts This cooler isn’t just about raw thermal performance — it’s about thermal control and stability. The build quality is solid, the 140mm A-RGB fans are quiet and efficient, and the integrated VRM fan adds practical cooling benefits in real-world builds like the HAVN. If you’re pushing high power settings or want maximum cooling headroom without going custom loop, this is an excellent upgrade.

## Features

- LGA1851 AND LGA1700 CONTACT FRAME: Improved contact pressure distribution through Intel mounting frame for efficient heat transfer, thanks to even CPU contact surface
- NATIVE AMD OFFSET MOUNTING: Optimized for the multi-die chiplet design of Ryzen processors - 5mm offset for optimal coverage of the CPU hotspot, resulting in more efficient heat transfer
- ACTIVE COOLING OF THE VOLTAGE CONVERTERS: PWM-controlled VRM fan that additionally cools components in the base area, such as voltage converters
- INTEGRATED CABLE MANAGEMENT: The PWM cables of the radiator fans are integrated into the jacket of the hoses, which means that only one visible cable is connected to the motherboard
- LIMITED COMPATIBILITY WITH A FEW MOTHERBOARDS: Oversized coolers on the M.2_1 slot can lead to compatibility problems. An overview and solution is available in the technical data, in the manual and on the manufacturer's website. Please use the compatibility check

### ⭐⭐⭐⭐⭐ Probably the Best AIO
*by J***H on April 12, 2026*

Probably the best AIO out there if you can fit it in your case. Great value for what you pay. Keeps my 9950x cool under a work load. Pretty quiet as well with the 140mm fans and large size radiator.
