What customers say
This flagship water block earns high praise primarily for its exceptional thermal performance and premium aesthetics. Users confirm it effectively manages demanding processors, delivering top tier cooling results. The combination of polished copper and durable acetal creates a visually striking, robust component that justifies its high end positioning. While the resulting performance is excellent, the installation process presents a notable challenge. Many customers find the mounting mechanism overly complex, requiring precise alignment and careful pressure management. Despite this initial hurdle, the consensus is clear: the Magnitude delivers unparalleled build quality and cooling efficiency, making it a highly recommended choice for custom loops prioritizing both looks and power.
Know before you buy
No, this specific model features a solid POM Acetal top and does not include any integrated RGB lighting. It is designed for users who prefer a clean, industrial aesthetic without LED illumination.
This block is compatible with Intel LGA-2066 and LGA-2011(-3) sockets, as well as the AMD AM4 socket. Please ensure your motherboard uses one of these specific mounting patterns before purchasing.
The convex shape is engineered to ensure optimal contact pressure across the CPU's integrated heat spreader. This design helps compensate for slight surface irregularities, ensuring the most efficient heat transfer possible.
The additional jet plate allows you to fine-tune the flow distribution within the block. While the pre-installed plate is optimized for general performance, the 0.6P plate gives enthusiasts the option to adjust internal flow dynamics to better suit their specific loop configuration.
The Magnitude is engineered for high-performance cooling with very low flow restriction. Its design, which includes a 50% larger fin array, allows coolant to pass through efficiently even in complex custom loops.
Yes, the block features a reversible port orientation. This flexibility allows you to route your tubing more easily depending on the layout of your custom liquid cooling loop.
