What customers say
This Supermicro passive heatsink earns high praise for its perfect compatibility and seamless integration with Supermicro server boards and chassis, making it the go-to solution for specific rackmount builds. Users value the robust, high-quality construction, which ensures long term durability for critical tasks. The core strength is its reliability in maintaining stable CPU temperatures when paired with adequate system airflow, a necessary condition for passive cooling. While the specialized nature justifies the cost, some find the pricing higher than standard consumer coolers. Overall, for its intended role as a perfectly fitting thermal component in high airflow server environments, sentiment remains overwhelmingly positive.
Know before you buy
A passive heatsink does not have its own integrated fan. It relies entirely on the high-velocity airflow generated by your server chassis fans to dissipate heat away from the CPU.
No, this heatsink is specifically engineered for 1U server chassis environments. It requires the high-pressure, directed airflow found in rackmount server systems to function correctly.
While it fits the LGA4189 socket, you must verify that your specific CPU's Thermal Design Power (TDP) falls within the cooling capacity of this 1U heatsink. Always check your server's manual or the Supermicro compatibility matrix before installation.
Most Supermicro heatsinks include a pre-applied thermal interface material (TIM) on the base. However, it is recommended to inspect the unit upon arrival and have a high-quality thermal compound on hand just in case you need to reapply it during installation.
Passive heatsinks are preferred in 1U server environments because they have no moving parts, which eliminates the risk of fan failure and reduces overall power consumption. They are ideal for high-density racks where system-level cooling is already managed by the chassis.
