There’s a unique thrill in planning a new PC build, especially when a new generation of processors hits the market. I remember the buzz around Intel’s 12th Gen “Alder Lake” chips. The leap in performance was undeniable, and for enthusiasts like us, the call to upgrade was strong. I had my new Core i7-12700K and a Z690 motherboard ready on the workbench. My trusty ARCTIC Liquid Freezer II 280, a cooler that has tamed every CPU I’ve thrown at it, was ready to be moved to its new home. Then came the gut-sinking moment every builder dreads: incompatibility. The mounting holes didn’t line up. The socket, now dubbed LGA1700, was a completely different shape and size. My high-performance, and not inexpensive, AIO cooler was suddenly useless. This is a scenario that has played out in thousands of workshops and home offices. The choice becomes a frustrating one: buy a brand new cooler and let the old one gather dust, or find a solution. That’s precisely where the ARCTIC Liquid Freezer II LGA1700 Upgrade Kit enters the narrative, not as an exciting new component, but as a crucial, problem-solving hero.

Before You Buy: What to Consider for a CPU Cooler Upgrade Path
A CPU cooler mounting kit is more than just a handful of screws and metal; it’s a key solution for ensuring longevity and value from your hardware investments. When CPU manufacturers change socket designs, as they inevitably do, they risk making entire ecosystems of third-party hardware obsolete. An upgrade kit like this one solves the critical problem of forward compatibility, allowing you to carry over a high-performance, expensive component like an AIO liquid cooler to a new platform. This not only saves you a significant amount of money but also reduces electronic waste. The primary benefit is financial and environmental, but the performance benefit is just as crucial: it enables your top-tier cooler to function with perfect mounting pressure on a new CPU, ensuring the thermal performance you originally paid for.
The ideal customer for this type of product is a specific but large group: any existing owner of an ARCTIC Liquid Freezer II series cooler who is planning to build or upgrade to a new PC using an Intel LGA1700 motherboard (for 12th, 13th, or 14th generation Intel Core processors). You are our target audience if you value the performance of your current cooler and want a cost-effective path to a new system. Conversely, this kit is not for you if you are building a new PC from scratch and don’t already own a Liquid Freezer II; in that case, you’d simply buy the latest revision of the cooler which includes the LGA1700 hardware. It is also, obviously, not for anyone building an AMD-based system. For those starting fresh, a complete cooler package is the only logical choice.
Before investing in a compatibility solution, consider these crucial points in detail:
- Compatibility & Revision: First and foremost, verify that your cooler is a Liquid Freezer II model. While this kit is designed for the series, it’s always wise to double-check. More importantly, ARCTIC has released different revisions of their coolers and kits over time. Check your cooler’s purchase date; if you bought it recently, it might already include the necessary parts. If you are buying a kit, ensure it’s the correct and most recent revision for your needs.
- Mounting Pressure & Design: A proper upgrade kit does more than just adapt to new mounting holes. The LGA1700 socket has a different “Z-height” than previous sockets, meaning the distance from the motherboard to the top of the CPU is different. This kit is specifically engineered with standoffs of a precise length to ensure the cooler’s cold plate makes perfect, even contact with the CPU’s heat spreader. Using a jury-rigged solution or an incompatible kit can lead to poor contact, resulting in dangerously high CPU temperatures.
- Kit Contents & Durability: Upon receiving the kit, immediately inventory the parts. A complete kit should include a new backplate, specific mounting brackets for the pump head, and the correct standoffs and thumbscrews. The material quality matters; the metal should feel robust and precisely machined. We’ve seen isolated user reports of parts breaking, so inspect everything for integrity before you begin disassembly of your system.
- Installation Process & Instructions: While the installation is generally straightforward for experienced builders, it’s not a simple snap-on process. You will need to remove your motherboard from the case to install the new backplate. Read the instructions carefully or, better yet, watch a video tutorial from a trusted source. A mistake here, like over-torquing a screw, can damage your motherboard or CPU permanently. The ARCTIC Liquid Freezer II LGA1700 Upgrade Kit aims for simplicity, but diligence is required.

Performance Under Pressure: A Deep Dive into the LGA1700 Upgrade Kit
A simple bag of metal parts can make or break a hundred-dollar cooler and a thousand-dollar system. The function of the ARCTIC Liquid Freezer II LGA1700 Upgrade Kit goes far beyond merely holding the cooler in place. It’s about ensuring a mechanically perfect interface between the cold plate and the CPU’s integrated heat spreader (IHS). We put the kit through a full installation and testing process to determine if it truly delivers on its promise of seamless, top-tier performance on Intel’s new platform.
The Installation Gauntlet: A Step-by-Step Experience
For many, the most daunting part of using an upgrade kit is the installation itself. Having performed this procedure, I can attest that while it requires patience, ARCTIC has made it as straightforward as possible. The process begins with the complete removal of the motherboard from the PC case—a necessary step to access the rear of the socket. We first removed the old LGA1200 mounting hardware from our motherboard. Then, we prepared the new ARCTIC backplate. Unlike some frustrating adjustable backplates, this one is a single, solid piece designed exclusively for LGA1700’s 78mm x 78mm spacing. It fits through the holes from the back with zero ambiguity.
Flipping the motherboard over, we threaded the four LGA1700 standoffs into the backplate. These are the most critical components in the bag, as their height is what dictates the final mounting pressure. They screwed in smoothly and felt secure. Next, we carefully placed our i7-12700K into the socket and applied our thermal paste. The final step on the motherboard side was placing the two new mounting arms onto the pump block of the Liquid Freezer II itself. With that done, we carefully lowered the cooler onto the CPU, aligning the arms with the standoffs, and secured it with the four thumbscrews in a cross-pattern to ensure even pressure. The entire process felt secure and logical. The parts fit perfectly, and at no point did we feel we were forcing anything. While our kit was complete and the parts were robust, we are aware of isolated reports from users receiving packages with missing pieces or experiencing a part breaking. We strongly advise inventorying and inspecting all parts before you start your build, a small step that can prevent a major headache.
Engineering Matters: Why Z-Height and Mounting Pressure are Crucial
Why can’t you just use washers or different screws? This is a question we see online, and the answer lies in the precise engineering of modern CPUs. The Intel LGA1700 socket introduced two major physical changes: a new rectangular CPU shape (from 37.5mm x 37.5mm to 37.5mm x 45mm) and a lower Z-height. This means the top surface of the CPU sits slightly lower relative to the motherboard surface than on previous generations. The ARCTIC Liquid Freezer II LGA1700 Upgrade Kit is more than just a bracket with new holes; it’s a recalibrated mounting system. The standoffs are shorter by a specific, calculated amount to compensate for this lower Z-height.
This precision is non-negotiable for optimal thermal performance. If the standoffs were too long (i.e., if you used the old LGA1200 ones), the cooler’s cold plate would make poor, uneven contact with the CPU’s heat spreader, or even hover just above it. This would create air gaps, which are disastrous for thermal conductivity, leading to immediate overheating and thermal throttling. Conversely, if the standoffs were too short, the mounting pressure would be dangerously high, risking physical damage to the CPU die or the motherboard socket itself. This kit provides the “Goldilocks” solution—the pressure is just right, ensuring a thin, even layer of thermal paste and maximum heat transfer from the CPU to the cooler’s cold plate. This meticulous engineering is the core value you are paying for.
Thermal Performance Before and After: The Ultimate Litmus Test
Talk of engineering and mounting pressure is meaningless without results. The ultimate question is: does a Liquid Freezer II mounted with this kit cool an LGA1700 CPU as well as a native cooler? To find out, we simulated a common upgrade path. We benchmarked our Liquid Freezer II 280 on an Intel Core i9-10900K (LGA1200), a notorious heat monster, noting its excellent performance. Then, we used the upgrade kit to mount that same cooler on our new test bench with an Intel Core i7-12700K (LGA1700), a chip known for its high power draw under load.
The results were exactly what we had hoped for. At idle, the 12700K sat at a cool 28-32°C, well within the expected range for this class of cooler. The real test, however, is under full load. We ran a 10-minute loop of Cinebench R23, a benchmark that pushes all CPU cores to 100%. The 12700K’s power package quickly ramped up to over 180 watts, yet the Liquid Freezer II, thanks to the perfect mount provided by the kit, held the line magnificently. Core temperatures stabilized in the low 80s Celsius, with no signs of thermal throttling. This is exceptional performance, on par with or even better than many newer AIOs designed natively for the LGA1700 socket. The test definitively proves that the ARCTIC Liquid Freezer II LGA1700 Upgrade Kit is not a compromise. It is a flawless bridge that allows one of the best AIOs ever made to continue its reign of thermal dominance on a new generation of hardware.
What Other Users Are Saying
While our hands-on experience with the kit was overwhelmingly positive, it’s crucial to consider the full spectrum of customer experiences. In our research, we found that the vast majority of users who successfully installed the kit were pleased with the outcome, echoing our findings on performance. However, we also came across some critical feedback that highlights potential issues. One particularly detailed account from a user in Europe mentioned receiving what they believed to be old stock with missing pieces. They also reported a critical part of the kit breaking during installation, something they had never experienced with other brands. Their frustration was compounded by a lack of response from the manufacturer’s customer service, forcing them to find another solution.
This feedback, while representing a minority, is important. It underscores the potential risks of quality control lapses and a customer support system that may be overwhelmed. It serves as a potent reminder for anyone purchasing the kit to buy from a reputable vendor and to inspect the contents thoroughly upon arrival. While our hardware was faultless, these reports suggest that your mileage may vary, and being prepared to act quickly if you receive a faulty or incomplete kit is a wise precaution.
