As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.

The UBJFMAC A26 2U cooler 280W handles high thermal loads for Threadripper sWRX8 or sTRX4 systems. It uses four heat pipes to dissipate up to 280W of heat in a compact 2U server chassis. This design suits dedicated workstations that need reliable socket compatibility and strong thermal performance. However, you might look for different dimensions, a lower price point, or quieter operation. Some builds require a smaller footprint or a different mounting style. You may also prefer a brand with a longer track record in server cooling.

This list features 6 alternatives that share key specifications with the original. Each option supports the SP3 socket family, ensuring it works with your Threadripper or EPYC processor. The selections include 2U active coolers for tight spaces and tower designs for standard cases. We chose these products because their specs overlap with the UBJFMAC model. You can compare heat pipe counts, physical dimensions, and TDP ratings. This approach helps you find a cooler that fits your specific case size and cooling needs without guessing.

Our top pick: UBJFMAC 2U Server Cooler with 4 Heat Pipes.

How each alternative compares

Dynatron 2U AMD SP3 Active CPU Cooler

The Dynatron T17 shares the 2U server height and SP3 socket compatibility with the UBJFMAC A26. It focuses on active cooling for Threadripper and EPYC builds. You get a practical option that fits tight spaces. The UBJFMAC model explicitly rates for 280W TDP with four heat pipes. The Dynatron does not list a specific wattage rating in the provided data. You might choose the Dynatron if you need broad socket support in a 2U chassis without a high TDP requirement. It lacks the explicit heat pipe count of the UBJFMAC. This makes it a solid budget choice for lower thermal loads.

SilverStone 2U SP3 Compact Server Cooler

The SilverStone SST-XE02-SP3S offers a compact 2U solution for AMD SP3 or TR4 processors. It is rated for 180W heat dissipation. This is lower than the 280W TDP rating of the UBJFMAC A26. The SilverStone model has a width of 3.11 inches and a height of 2.52 inches. The UBJFMAC does not list these specific dimensions. You should pick the SilverStone if you need a trusted brand for compact server cooling. You give up some thermal headroom compared to the UBJFMAC. It is a solid choice for systems that do not reach the maximum thermal output of high-end Threadripper CPUs.

Noctua 120mm SP3 Threadripper Tower Cooler

The Noctua NH-U12S TR4-SP3 is a 120mm tower cooler, not a 2U server cooler. It has a height of 6.22 inches. This is much taller than the 2U form factor of the UBJFMAC. It fits users prioritizing low noise in a compact tower form factor. The UBJFMAC uses four heat pipes for 280W loads. The Noctua model weighs 1.76 pounds. You should choose this if you are building a workstation where space allows for a taller cooler. You gain quieter operation. You lose the ability to fit into a standard 2U server chassis. It is better for desktop workstations than for rack-mounted servers.

Noctua NH-U9 Workstation CPU Cooler

The Noctua NH-U9 TR4-SP3 is a 92mm server cooler with a height of 4.92 inches. It is still taller than the 2U limit of the UBJFMAC. It fits workstations with tight PCIe clearance. The UBJFMAC is designed specifically for 2U chassis. This Noctua model weighs 2.2 pounds. You get reliable cooling for Threadripper and EPYC CPUs. You give up the compact 2U profile of the UBJFMAC. It is a good choice for users who need more height than 2U allows. It is not suitable for strict 2U server cases. You prioritize space constraints over the ultra-compact design of the UBJFMAC.

Cooler Master Hyper 212 Black CPU Cooler

The Cooler Master Hyper 212 Black is a standard desktop CPU cooler. It has four heat pipes like the UBJFMAC. However, it is not designed for 2U server chassis. Its height is 6.3 inches. This is significantly taller than the 2U form factor. It is a solid choice for standard desktops. You prioritize compatibility and noise levels over maximum thermal capacity. The UBJFMAC is built for server environments. You should pick the Cooler Master if you are building a regular desktop. You cannot use this in a 2U server case. It lacks the specific socket compatibility for Threadripper server builds.

Dynatron Aluminum Side-Fan CPU Cooler

The Dynatron A38 Aluminum Server Cooler is a side-fan design with a height of 3 inches. It is taller than the 2U limit. It offers a compact, socket-specific solution for Threadripper and EPYC builds. The UBJFMAC uses four heat pipes. The Dynatron A38 is made of aluminum. You prioritize size and ease of setup. You give up the heat pipe count of the UBJFMAC. It is not rated for 280W TDP. You should choose this if you need a specific socket fit in a slightly taller case. It is not a direct 2U alternative. You accept a different form factor for easier installation.
