Looking Beyond the ASHATA 1U Passive LGA 2011? 6 Alternatives Worth a Look
As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
You are looking for ASHATA 1U Passive Heatsink CPU cooler alternatives, perhaps because the ASHATA SNK-P0047P does not fit your specific socket or chassis needs. This original heatsink is a passive, metal unit designed for LGA 2011 sockets in Supermicro X9 or X10 1U servers. It relies on case airflow to dissipate heat, offering a silent, fanless solution that weighs just 7.69 ounces. Its compact 0.39-inch height ensures it fits in tight server enclosures without obstructing other components.
However, you might need a different socket compatibility, such as AM4 or LGA 4189, or a different material like copper for better thermal conductivity. Some builds require support for older sockets like LGA 1150 or LGA 1366. The alternatives listed here were chosen because their specifications overlap with the original product. Each option maintains the 1U form factor and passive cooling method, ensuring they fit in similar server chassis. You can compare their dimensions, weights, and socket support to find the right fit for your system.
Our top pick: ASHATA 1U Passive LGA 2011 Server Heatsink.
Key differences in these alternatives
SilverStone 1U Passive Copper Server Heatsink
The SilverStone SST-XE01-2011 uses copper instead of the ASHATA’s general metal construction. Copper offers higher thermal conductivity, which helps move heat away from the CPU faster. It shares the same 1U passive design and LGA 2011 socket compatibility. However, it is significantly larger and heavier. The SilverStone unit measures 3.54 inches square and weighs 1.08 pounds, compared to the ASHATA’s tiny 0.39-inch profile and 7.69 ounces. This size difference matters in tight 1U chassis. Choose this if you need better heat transfer and have the physical space. Avoid it if your server case has strict clearance limits under the ASHATA dimensions.
Dynatron 1U AM4 Copper Passive Heatsink
The Dynatron A37 shifts the focus to AMD AM4 sockets rather than Intel LGA 2011. It retains the passive, 1U form factor and copper material for efficient heat dissipation. The dimensions are 3 by 5 inches with a 1-inch height. This is taller and longer than the ASHATA unit. It is not compatible with your LGA 2011 processor. Pick this alternative only if you are building an AMD-based 1U server. It provides silent operation similar to the ASHATA but for a different platform. Do not buy this if you are sticking with Intel Xeon or Core processors in the LGA 2011 socket.
BVIVDMIWF 1U LGA4189 Passive Heatsink
The BVIVDMIWF heatsink targets LGA4189 sockets, making it incompatible with LGA 2011. It features a vapor chamber, a technology that spreads heat more evenly than standard fin stacks. This can improve thermal performance in passive scenarios. The listing does not specify exact dimensions or weight, so physical fitment requires careful verification. It is designed for 1U server chassis. Select this if you are using an LGA4189 processor and need advanced heat spreading. It offers a different cooling mechanism than the ASHATA. Skip this option if your system relies on LGA 2011 or other Intel sockets.
Supermicro 1U Passive Server Heatsink
The Supermicro SNK-P0037P supports LGA1366 sockets, not LGA 2011. It is a passive, 1U heatsink designed for Xeon 5500 series processors. The unit measures 25 inches in one dimension, which is unusually large compared to the ASHATA. It weighs 12.8 ounces, slightly more than the ASHATA. This size suggests it is for a different motherboard layout or server form factor. Choose this if you have an older LGA1366 Xeon build. It provides silent cooling for that specific socket. Do not use this for LGA 2011 systems, as the socket compatibility does not match.
Supermicro 1U Passive Server Heatsink
The Supermicro SNK-P0046P is built for LGA 1150 and LGA 1155 sockets. It is a passive, 1U cooler, sharing the same general design philosophy as the ASHATA. The dimensions are 1.1 by 3.6 inches, weighing 8 ounces. It is slightly wider and heavier than the ASHATA unit. This heatsink is not compatible with LGA 2011 processors. It fits well in X8 and X9 chassis. Pick this if you are upgrading an older LGA 1150 or 1155 system. It offers a compact, silent solution for those specific Intel sockets. Avoid it for LGA 2011 builds.
Supermicro 1U Passive Server CPU Heatsink
The Supermicro SNK-P0042P supports AMD Socket G34 and Socket F. It is a passive, 1U heatsink designed for server environments. The dimensions are 1.02 by 3.94 inches, weighing 14.4 ounces. It is larger and heavier than the ASHATA LGA 2011 unit. This alternative is not suitable for Intel sockets. Choose this if you are building or maintaining an AMD Opteron server with G34 or F sockets. It provides silent cooling in a compact 1U profile. Do not select this for LGA 2011 systems, as the socket type is completely different.
