6 Best Alternatives to the Boartechs 2U LGA4677 5-Heatpipe Server (2026)

How each alternative compares

CTDOFUM 2U LGA4677 5-Heatpipe Cooler

The CTDOFUM cooler matches the Boartechs model with five heat pipes and a 2U profile for LGA4677 sockets. It targets the same 400W TDP support for 4th and 5th gen Xeons. You get a similar aluminum construction in a silver finish. The key difference is the included E1B bracket, which may suit your specific mounting requirements better than the standard setup. If you need a direct functional swap with potentially different bracket compatibility, this is a practical choice. It offers the same core cooling performance without adding extra features, keeping the design simple and focused on heat dissipation for your server build.

JUCMJXQEQ 2U LGA4677 5-Heatpipe Server Cooler

The JUCMJXQEQ cooler provides another five-heatpipe, 2U option for LGA4677 servers needing 400W cooling. It uses a silver aluminum design similar to the Boartechs unit. The main distinction lies in the mounting hardware, as this model comes with an E1A bracket. This specific bracket might align better with your chassis mounting points. Like the original, it is built for robust server workloads and reliable heat dissipation. If your current setup requires the E1A bracket or you simply want a comparable cooling solution with different mounting geometry, this alternative serves as a direct replacement. It maintains the essential specifications for your LGA4677 processor while offering slight hardware variations.

KFXJMY 2U 5 Heat Pipe Server Cooler

The KFXJMY cooler differs by supporting both LGA4677 and LGA4710 sockets, offering broader compatibility than the Boartechs model which is limited to LGA4677. It retains the five-heatpipe, 2U active design with a fan. This unit features a black color and RGB lighting attributes, though the size spec notes no RGB, suggesting the lighting may be an option or separate. If you need a cooler that can adapt to multiple socket types or prefer a black aesthetic, this is a strong alternative. It provides the same 2U active cooling performance but adds versatility in socket support and visual customization options for your server environment.

Supermicro 2U Server Heatsink

The Supermicro heatsink is designed for LGA2011 sockets, making it incompatible with your LGA4677 Boartechs cooler. It is a 2U server heatsink weighing 10 pounds, which is significantly heavier than the 2.2-pound Boartechs unit. This product is intended for Intel Xeon E5 processors in narrow 2U chassis. If you are upgrading or building a server with LGA2011 sockets instead of LGA4677, this Supermicro option provides the necessary mounting support and thermal mass for enterprise workloads. It serves a completely different socket family, so it is only relevant if your processor socket type differs from the original Boartechs recommendation.

MITXPC Threadripper EPYC Passive 2U Heatsink

The MITXPC passive heatsink is designed for AMD Threadripper and EPYC processors using the SP3 socket, not Intel LGA4677. It is a 2U passive cooler, meaning it relies on case airflow rather than an attached fan like the Boartechs model. This makes it suitable for silent builds with dedicated airflow paths. The dimensions are 3.15 inches wide, 2.52 inches high, and 4.45 inches long. If you are working with AMD Threadripper or EPYC CPUs and need a fanless 2U solution, this is the appropriate choice. It does not fit LGA4677 sockets, so it is only an alternative if you are changing your processor platform entirely.

YQQEWI 2U LGA 2011 Passive Server Heatsink

The YQQEWI passive heatsink is built for LGA2011 Narrow sockets, not LGA4677. It is a 2U silent solution that requires existing server airflow, as it lacks an active fan. Weighing only 1.76 ounces, it is much lighter than the Boartechs cooler. It features a black color and A-RGB size specification, though as a passive unit, the lighting is purely aesthetic. This heatsink is ideal for LGA2011 builds where silence is a priority and airflow is managed by case fans. It does not support LGA4677, so it is only a viable alternative if you are using LGA2011 processors and prefer passive cooling over the active 5-heatpipe design.
