The lack of RGB and the heavy weight are minor concessions. If you demand the best air cooler on the market today, the LongMint 9 is your answer. Whether you are building a silent media server or a high-octane gaming rig, this cooler delivers "long mint" performance—cool, quiet, and enduring. The LongMint 9 is available via Amazon, Newegg, and the official LongMint webstore. Look for the "Revision B" model released in Q2 2024, which includes the LGA 1851 mounting hardware for Intel Arrow Lake processors.
The graphene coating on the aluminum fins serves two purposes: it improves radiative heat transfer (how heat leaves the fins) and gives the cooler a sleek, matte black finish that resists corrosion. The top plate features a brushed aluminum cover with the LongMint logo, hiding the heat pipe terminations for a clean, premium look. Anyone who has installed a dual-tower air cooler knows the struggle: bloody knuckles, awkward screw alignment, and backplates that fall out mid-installation. The LongMint 9 solves this with a tool-less mounting bracket . The system uses a pre-installed backplate (with adhesive strips to keep it in place) and spring-loaded screws that click when properly torqued. longmint 9
For AMD AM5 users, the cooler uses the stock backplate, but LongMint includes a custom mounting frame that prevents the CPU from bending under pressure—a common issue with heavy coolers. The entire installation process, from removing the old cooler to booting up, took roughly 8 minutes in our test bench. The only minor gripe? The fan clips are slightly too rigid, requiring a flathead screwdriver to pry open. We tested the LongMint 9 against two heavyweights: the Noctua NH-D15 and the Deepcool Assassin IV. The test bench used an Intel Core i9-14900K (a notoriously hot chip) running at stock speeds (125W base, 253W PL2) in a 22°C ambient room. The lack of RGB and the heavy weight are minor concessions
This article provides a comprehensive deep-dive into the LongMint 9, exploring its design philosophy, technical specifications, real-world performance, and how it stacks up against the competition. The LongMint 9 is a flagship dual-tower air cooler designed for high-TDP (Thermal Design Power) processors from Intel (LGA 1700/1851) and AMD (AM5). Unlike its predecessor, the LongMint 7, the new "9" series introduces a radical shift in fin density and heat pipe architecture. It is not merely an incremental update; it is a complete re-engineering of how air moves through a heatsink. The LongMint 9 is available via Amazon, Newegg,
