Large-scale CPU Water Cooling: The Liquid Freezer II 420

Liquid Freezer II 420 Liquid cooler launch

“Will ARCTIC ever release the Liquid Freezer II in bigger sizes?”

This is one of the most common questions we get from our social media community about our award-winning Liquid Freezer II CPU water cooling series. Well, now we can give you a straight answer: Yes, we will!

Meet the Liquid Freezer II 420. With three 140 mm ARCTIC P-fans and a 458 mm-long radiator, the Liquid Freezer II 420 is ARCTIC’s largest and most powerful liquid cooler yet.

Since its release at the end of 2019, our all-in-one series Liquid Freezer II has been winning over hardware enthusiasts and independent tech reviewers worldwide.

If you’re planning to boost your gaming rig and could use a fresh ARCTIC breeze, this is definitely the CPU cooler to add to your Christmas list! For the extremely low price of 119.99€ and $139.99 here’s what you can expect:

  • Compatible with Intel & AMD Sockets
  • In-house Developed PWM Controlled Pump
  • High Performance allows Overclocking
  • Motherboard VRM Cooling Solution
  • Pressure Optimised Fans
  • Fully Sleeved Tubes
  • Integrated Cable Management
  • Maintenance-free Water Loop
  • Secure Hold with Backplate
  • MX-4 Thermal Paste Included

By the way, here’s the second most-asked question about the Liquid Freezer II: “Are we ever going to get a white version of the Liquid Freezer II?”

Guess you’ll have to stay tuned for a bit longer to find it out!

Liquid Freezer II Second Revision – What’s Changed?

Liquid Freezer Rev. 2

Because we are constantly improving our products–for example to increase their efficiency– it occasionally happens that they are available in different revisions. This is the case with the new Liquid Freezer II. To avoid confusion about the changes, we have summarized them for you here:

  1. At launch, the P-fans of the Liquid Freezer II had a 0 dB mode. They stopped when the PWM signal was below 10%. Due to increased RMA rates from customers who thought their fans were defective, the 0 dB mode was canceled for all fans and coolers and the minimum speed increased to 200 revolutions per minute.
  2. Since the new revision, additional screws have been added to the water cooler to simplify installation in pull configuration. You can find animated instructions for this at support.arctic.ac.
  3. Similar to the motor hubs of our fans, a print of the technical specifications of the cooler is now printed on the underside of the pump unit. This allows you to calculate its maximum power consumption and check compatibility with the fan headers of your Mainboard.
  4. The integrated cable management of the Liquid Freezer II has been further improved, so that the cables are installed on the back of the radiator and disappear from your field of vision.
  5. The connection of the VRM fan no longer sits directly on the PCB, but hangs on a short cable. This minimizes the risk of damaging the connection when deactivated.
  6. The last revision of the Liquid Freezer II gave an incorrect value of the pump as RPM value. Now the value of the radiator fans is output instead. So be sure to deactivate the CPU fan error warning in the BIOS if you want to operate them separately.

Our award-winning Liquid Freezer II is currently in its second revision. You can recognize it from the outside by the small Rev.2 next to the barcode on the packaging. Its performance and main characteristics remained unchanged, so it’s still the same great product.

ARCTIC SNEAK PEEK: LIQUID FREEZER II SERIES

Liquid Freezer II

Psst…want to see something cool?

We’re just about ready to launch our Liquid Freezer II Series, the highly anticipated follow-up to our original AiO water cooler. While we can’t share all the details just yet, we can give you sneak peek. This way, you can see for yourself just how good it’s going to look in your in your system.

We’ll let Vincent André, our Technical Director, tell:

Some technical details…

The pump is powered by a three-phase motor, which allows it to achieve higher efficiency and smoother operation. When we got the idea to add a VR cooling fan, which came with further integration challenges. This, however, went well with the choice of the 40mm diagonal fan and its integration over the cooling plate. We’re also quite proud of the cable management, as there are almost no visible cables in the product, even for the 360 variant.

About the new pump…

ARCTIC is a company that puts innovation at the core of its product line, but we found ourselves using the same pump as most of the competition in the market. So, we saw this as an opportunity to challenge ourselves by bringing our own design to the market. Further, having worked with Asetek, we also knew both what aspects of their module was great and what aspects didn’t work well for us. We took great care to match them on the strengths while adding solutions for our ARCTIC-specific needs.

About the challenges in process…

As explained before, the patent protection was one of them. The second and biggest was actually the experience: experience can’t be acquired just by downloading it. You need to test things, fail, learn from missed attempts, then repeat that again and again until experience comes. Going into it, we already knew a lot about water cooling, but doing it ourselves made us learn way more deeply. Some things that seemed trivial were, in reality, very different than we had anticipated. In addition to acquiring the experience needed to create great CPU cooler, we of course did not want to release a product without thoroughly testing it. We spent time making sure that the cooler would not only work for the user when they get it, but also for years to come. Value for money is a core ARCTIC principle, and for that reason, we spent a lot of time refining the design but even more time making sure the production process was totally mastered.

Value for money, indeed! But don’t take our word for it. We let a few people check out the prototype earlier this year. Here’s what they had to say:

Liquid Cooling Solutions – Step Up Your Cooling System

Every computer, from home theater PC to the most hulking of gaming system, generates heat during operation- and this heat can kill your PC’s precious internals if you’re not careful.  For quite some time, air cooling systems were the solution to stop the CPU and GPU from overheating. As this method is quite successful, air coolers are still extremely popular in the marketplace. But there are some new solutions, as well.

The Next Level of Cooling

Over the time, cooling solutions were reworked to new sizes and methods. Thereby, liquid coolers became the next level of cooling. Especially for the CPU, this method becomes more and more popular. Here, the liquid used is a low conductive mixture that loops from the radiator to the CPU block which dissipates heat faster than air cooling does. That way, the CPU will run cooler at idle and under load.

No Worries

New liquid coolers are quiet, save internal space where it matters most, and perform well – all at a price that’s not far off from a good air cooler. Who thinks that water and a computer system won’t go together can be reassured.  When you follow the installation instructions correctly, there should be no leaks and therefore, your system stays dry. Moreover, thanks to the innovation of all-in-one water coolers like the ARCTIC Liquid Freezer, there is only need to install it once and the cooler won’t require to be maintained constantly in the future.

Easy Installation

The easiest way to get into liquid cooling is with an all-in-one loop. These consist of a single closed loop with a radiator on one end and a pump/water block combo on the other. The system is pre-filled and pre-sealed so you don’t need to mess with it. You just install the radiator and its included fan onto one of your case’s existing fan mounts, attach the water block to the CPU and fire it up.
Most all-in-one loops cool the CPU only. There are some all-in-one loops for GPUs, like our ARCTIC Accelero.
