Who it fits

Key specs explained

Material: Copper skived-fin and copper base

The cooler uses copper for both the base and the fins. Skived fins are cut from a solid block of metal, which creates thinner and denser fins than extruded methods. This construction improves thermal conductivity and surface area. You get better heat transfer from the processor to the air. Copper is a standard choice for high-performance server cooling, offering reliability in tight spaces.

Cooling Method: Passive

This unit has no fans. It relies on natural air convection or external case airflow to move heat away. This design eliminates moving parts, reducing noise and potential points of failure. It is ideal for environments where silence is critical or where fans are impractical. You must ensure your server chassis provides adequate airflow through the heatsink fins for effective cooling.

Server Height: 1U

The cooler is designed for 1U rackmount servers, which are extremely thin enclosures. The physical height is approximately 26mm. This low profile allows it to fit into standard server racks without interfering with other components. You need a chassis specifically designed for low-profile cooling solutions. This spec ensures compatibility with enterprise-grade server hardware that requires compact form factors.

Socket Compatibility: LGA2011/2066

This heatsink mounts only to Intel LGA2011 and LGA2066 sockets. It is not compatible with consumer sockets like LGA115x or AM4. These sockets are typically found in workstation and server platforms. You must verify your motherboard socket before purchasing. Using it on an unsupported platform is impossible. This restriction limits its use to specific high-end desktop or server builds.

Design and build details

The listing specifies a copper base paired with copper skived fins. This material choice prioritizes thermal conductivity over cost savings. Skived fins are cut from a solid block, creating thinner and denser structures than extruded alternatives. This construction maximizes surface area for heat dissipation within a restricted volume. The unit stands 26mm tall, which aligns with the 1U server height requirement. Its dimensions are 3.54 inches in width and length, with a total height of 1.02 inches. This compact footprint allows it to fit into standard rackmount enclosures without obstructing adjacent components.

According to the listing, the cooler weighs 1.08 pounds. This mass helps stabilize the unit in server chassis where airflow is directed by case fans rather than integrated fans. The design lacks active components, meaning it relies entirely on system airflow for cooling. It is compatible with Intel LGA2011 and LGA2066 sockets. This specificity limits its use to compatible server platforms. The finish is not detailed beyond the copper material description. You must ensure your server chassis provides adequate front-to-back airflow to utilize this passive solution effectively. The build focuses on durability and thermal efficiency in a constrained space.

Setup and everyday use

You will install this cooler in a standard 1U rackmount server chassis. The unit measures 1.02 inches in height, which matches the 26mm profile listed. This low profile ensures it fits within tight server enclosures without interfering with adjacent components. You must verify that your motherboard supports either the LGA2011 or LGA2066 socket. The listing confirms compatibility with these specific Intel platforms. It is not designed for consumer desktop motherboards. Installation involves mounting the copper base directly to the CPU. The cooler relies entirely on passive cooling. There are no fans or active components included. This means you must ensure your server case has adequate airflow. The system needs strong front-to-back air movement to dissipate heat through the dense copper skived fins. The cooler weighs 1.08 pounds. This weight is substantial for its small size. You should check that the mounting hardware can support this mass without stressing the motherboard. Daily operation depends on the server’s cooling solution. The heatsink transfers heat from the processor to the fins. The case fans then move air across those fins. This setup is ideal for environments where noise is a concern or where fan failure is unacceptable. It provides consistent thermal performance as long as airflow remains steady. You do not need to manage fan curves or RPMs for this unit. It operates silently by design. This makes it suitable for data centers or quiet server rooms. The copper construction ensures efficient heat spreading. You rely on the server’s existing cooling infrastructure to handle the rest.

Before You Buy This Cooler

This cooler requires active airflow from your server’s chassis fans to function. You must verify that your case provides sufficient air pressure across the dense skived fins. The unit is strictly for LGA 2011 and LGA 2066 sockets. Do not attempt to mount it on consumer desktop boards like LGA 1700 or AM5. You need a server motherboard with compatible mounting holes. Passive designs rely entirely on case ventilation. If your server fans are weak or clogged with dust, this copper block will not cool enough. Regular cleaning of the fins is essential to maintain performance. This option suits specialized 1U rackmount environments where space is tight. It does not fit standard ATX towers. You should compare this against active 1U coolers if your airflow is limited. Passive units offer silence but demand strict airflow management. Check your thermal design power limits before purchasing.

Check before you buy

• Verify your server chassis supports 1U height constraints
• Confirm your motherboard uses LGA 2011 or LGA 2066 sockets
• Ensure your case fans provide strong, directed airflow through the fins
• Check that your CPU thermal output fits passive cooling limits
