Description
TL;DR: The LTPA-4189 and LTPA-4677 are split-design server-grade CPU water blocks for Intel's narrow-ILM Xeon platforms - LTPA-4189 for socket LGA 4189 (3rd Gen Xeon Scalable, Ice Lake-SP / Cooper Lake-SP) and LTPA-4677 for socket LGA 4677 (4th and 5th Gen Xeon Scalable, Sapphire Rapids and Emerald...
The LTPA-4189 and LTPA-4677 are split-design server-grade CPU water blocks for Intel's narrow-ILM Xeon platforms - LTPA-4189 for socket LGA 4189 (3rd Gen Xeon Scalable, Ice Lake-SP / Cooper Lake-SP) and LTPA-4677 for socket LGA 4677 (4th and 5th Gen Xeon Scalable, Sapphire Rapids and Emerald Rapids). The two-piece body bolts to the socket retention frame and exposes G1/4 inlet/outlet ports. The block is targeted at sustained AI, HPC and cloud-computing workloads.
Q: Which Intel sockets are supported?
A: LTPA-4189 fits socket LGA 4189 (3rd Gen Xeon Scalable, Ice Lake-SP and Cooper Lake-SP). LTPA-4677 fits socket LGA 4677 (4th and 5th Gen Xeon Scalable, Sapphire Rapids and Emerald Rapids).
Q: What port size does it use?
A: Standard G1/4 BSPP inlet and outlet, compatible with any mainstream water-cooling fitting.
Q: Is it suitable for 24/7 server operation?
A: Yes, the block is built for continuous AI and cloud workloads. An upstream in-line filter is recommended for any fine-channel server cold plate.
Q: Does it ship with mounting hardware?
A: Yes. Mounting screws sized for the chosen LGA 4189 or LGA 4677 retention are included.
Q: Why a split / two-piece block?
A: The split design lets the cold plate sit flat across the long Xeon IHS while the retention frame bolts independently to the socket.
