Supporting Intel's Latest Innovations: LGA1851 Socket and RL-ILM
The Core Ultra 200S CPUs bring significant architectural changes designed to enhance efficiency and lower temperatures. While Intel’s improvements to semiconductor architecture play a big part, there’s also been a design change in the form of a new socket: the LGA1851, paired with the RL-ILM (Reduced Load - Integrated Lever Mechanism).
The RL-ILM aims to address some of the common thermal and mechanical issues present in older mechanisms by reducing the loading pressure and providing a flatter load plate. This change mitigates the risk of the CPU's IHS (Integrated Heat Spreader) bending, ensuring more consistent and direct contact with the cooling plate. Cooler Master has always prioritized high-quality engineering, which is why many of our cooling solutions—designed for the previous LGA1700—are also compatible with LGA1851 (See Table).
Compatibility You Can Trust
Whether you’re using the flagship MasterLiquid Ion Series or the versatile MasterLiquid Core Series, your Cooler Master cooling solution is ready to deliver exceptional performance with Intel’s latest CPUs. Here’s how our cooling solutions fit perfectly with the new socket:
• LGA1851 Compatibility: All of Cooler Master’s cooling solutions that supported the LGA1700 socket are compatible with LGA1851. This includes our most advanced liquid coolers, engineered with the versatility to fit evolving standards and maximize cooling efficiency.
• RL-ILM Compatibility: Not all Cooler Master cooling solutions support Intel's RL-ILM (Reduced Load - Integrated Lever Mechanism). RL-ILM features lower load pressure on the CPU but requires greater mounting pressure from the cooler—up to 35 pounds. While some LGA1700-compatible coolers can meet this requirement, others may not.
This table shows our current retail products that support both LGA 1851 and RL-ILM. It will help you identify which Cooler Master cooling solutions are compatible with Intel's latest advancements.

Understanding the Evolution from ILM to RL-ILM
The RL-ILM is a leap forward in protecting the longevity and efficiency of your CPU. The older ILM utilized a higher loading pressure, which often led to bending in the CPU’s IHS. This bending could interfere with cooler-to-IHS contact, diminishing the cooling efficiency and raising the risk of CPU malfunction.
In contrast, the RL-ILM reduces the loading force, preventing the IHS from bending and ensuring an even, solid contact between the CPU and the cooling solution. This means lower CPU temperatures and better reliability, but it requires a CPU cooler with stronger mounting pressure (35 pounds)—which is where Cooler Master’s commitment to quality comes in. Our solutions are engineered to meet and exceed these mounting requirements, providing users with the full thermal advantages of Intel’s latest design.
Practical Tips for Upgrading
When upgrading to Intel’s new Core Ultra 200S CPUs, it’s important to ensure your entire system is RL-ILM-ready:
1. Check Your Motherboard: Not all motherboards with the LGA1851 socket automatically include the RL-ILM. Be sure to verify if your motherboard uses the updated mechanism, as the benefits of the RL-ILM will only be realized when both the CPU Socket and cooler are compatible.
2. Optimal Cooler Pressure: To gain the maximum advantages of the RL-ILM, ensure your cooler provides strong mounting pressure. Cooler Master’s solutions are designed to beat usual standards, so you’re covered.
3. Cooling Compatibility: Refer to our compatibility list for detailed information about which coolers are ready to deliver top-tier performance for Intel’s latest CPUs.
