As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
The JUCMJXQEQ 2U LGA4677 4th & 5th CPU Cooler handles high-TDP server loads with five heat pipes. You might seek jucmjxqeq 2u lga4677 4th alternatives if you need a different bracket, socket support, or passive cooling. This list covers 6 options that share the 2U server height and LGA4677 compatibility. Each alternative was chosen because its specifications overlap with the original product's core requirements.
The original model uses an E1A bracket and offers silver finish with PWM fan support. Some users may prefer the E1B bracket found in the CTDOFUM option. Others might need LGA4710 support, which the KFXJMY and YQQEWI models provide. If you require a passive solution for silent operation, the MITXPC heatsink is a valid choice. The Supermicro unit serves a different socket entirely but fits the same 2U chassis. You can compare these specs to find the best fit for your specific server build.
Our top pick: JUCMJXQEQ 2U LGA4677 5-Heatpipe Server Cooler.
How these alternatives compare
CTDOFUM 2U LGA4677 5-Heatpipe Cooler
The CTDOFUM cooler matches the JUCMJXQEQ with five heat pipes and a 2U server height for LGA4677 sockets. It distinguishes itself by including an E1B bracket, whereas the original uses an E1A bracket. This difference matters for your specific chassis mounting requirements. Both units are silver and designed for high-TDP server processors. If your server frame requires the E1B mounting configuration, this CTDOFUM model is the direct swap. It provides identical thermal capacity through its heat pipe count but ensures physical compatibility with your existing bracket setup without modification.
KFXJMY 2U 5 Heat Pipe Server Cooler
This KFXJMY unit offers five heat pipes and a 2U height like the original, but it supports both LGA4677 and LGA4710 sockets. This broader socket compatibility makes it useful if you plan to upgrade to newer processors later. It is available in black, differing from the silver JUCMJXQEQ. The listing notes RGB lighting attributes, though the size spec says NO RGB, so verify the exact fan configuration before buying. It is a strong choice for administrators managing mixed-socket environments who need a single cooler solution for multiple server generations within the same rack.
Boartechs 2U LGA4677 5-Heatpipe Server Cooler
The Boartechs cooler provides five heat pipes and a 2U height for LGA4677 servers, matching the thermal design of the JUCMJXQEQ. It uses the 4677-2UAF8 cooler size specification. A key difference is the weight, listed at 2.2 pounds, which may affect airflow resistance or mounting stress in tight 2U chassis. It is suitable for users needing reliable cooling for 4th and 5th gen Intel Xeon processors. If you require a standard AF8 cooler form factor with similar heat pipe density, this model serves as a functional alternative for standard server builds.
YQQEWI 2U Active Server Cooler
The YQQEWI active server cooler supports both LGA4677 and LGA4710 sockets in a 2U height, offering broader compatibility than the LGA4677-only JUCMJXQEQ. It is black and includes RGB lighting attributes, which the original does not mention. This cooler is designed for standard 2U server racks where visual indicators or aesthetic lighting are desired. If you need to cool newer LGA4710 processors or prefer RGB fans for rack visibility, this unit provides those features while maintaining the 2U form factor and active cooling method required for high-TDP server workloads.
Supermicro 2U Server Heatsink
The Supermicro heatsink targets LGA2011 sockets, making it incompatible with the LGA4677 socket of the JUCMJXQEQ. It is designed for Intel Xeon E5-2600 series processors in dual-processor server builds. This unit weighs 10 pounds, significantly heavier than the JUCMJXQEQ, indicating a different thermal mass and construction approach. It is strictly for LGA2011 systems, so it is not an alternative for your current 4th or 5th gen LGA4677 CPU. Choose this only if you are building a separate server platform using the older LGA2011 architecture.
MITXPC Threadripper EPYC Passive 2U Heatsink
The MITXPC Dynatron A34 is a passive 2U heatsink for AMD SP3 sockets, which differs from the active, LGA4677 JUCMJXQEQ. It requires you to supply your own airflow, unlike the PWM fan included with the original. This makes it suitable for silent builds where noise is a priority. The dimensions are 3.15 by 2.52 by 4.45 inches. It is not compatible with Intel LGA4677 processors. Select this only if you are building an AMD SP3 server and can ensure adequate case airflow to compensate for the lack of an integrated fan.
