The SP5 CPU Water Block is purpose-built for the AMD EPYC SP5 platform, offering a custom-fit cold plate that perfectly matches the CPU heatspreader dimensions. This ensures even thermal distribution across the entire processor surface, minimizing hotspots and maintaining consistent cooling efficiency.
It is fully compatible with AMD EPYC 9004 Series (Genoa/Bergamo) processors, making it the ideal choice for server integrators, OEM system builders, and data center solution providers seeking dependable SP5 cooling performance.

Featuring a precision-machined microchannel structure or pin-fin array, the SP5 water block delivers superior heat transfer efficiency. Each microchannel is optimized through CFD (Computational Fluid Dynamics) simulation to maximize coolant flow and minimize thermal resistance.
This design significantly enhances liquid-to-surface heat exchange, ensuring high thermal conductivity and low junction temperatures even at extreme CPU loads.
The result is improved processor stability, extended component life, and reduced fan noise compared to traditional air cooling systems.
Key Advantages:
Microchannel or pin-fin internal structure for optimized flow
Uniform cooling across the CPU die area
Reduced thermal resistance (<0.05 °C/W)
Support for high coolant flow rates up to 6 L/min
The SP5 CPU Water Block is crafted using high-purity copper or industrial-grade aluminum, both chosen for their excellent thermal conductivity and mechanical strength.
For enhanced durability and corrosion protection, the surface can be nickel-plated, anodized, or left bare based on system requirements.
Material Options:
Base: Copper / Aluminum
Surface Finish: Nickel Plated, Anodized, or Bare
Top Cover: Aluminum, Acrylic, or Stainless Steel
Sealing: High-temperature industrial-grade O-rings
This combination of materials ensures the water block maintains stable performance even under continuous 24/7 operation in high-density server environments.
Every SP5 water block is leak-proof by design. It uses industrial-grade seals, precision-machined threads, and is pressure-tested up to 1.5 bar (21.7 psi) to ensure zero leakage during operation.
The internal structure is assembled under strict quality control standards, making it reliable for mission-critical data center cooling systems and OEM liquid-cooled servers.
Technical Reliability Highlights:
Leak-tested at 1.5 bar
Long-life O-ring sealing system
Compatible with glycol-based and deionized water coolants
Supports 24/7 continuous operation
The water block supports standard G1/4” threaded ports, allowing compatibility with most liquid cooling fittings, tubing sizes, and quick-disconnect systems.
OEMs and integrators can also request custom port orientation, mounting hole patterns, and manifold integration for large-scale deployments.
Mounting & Port Options:
Thread Type: G1/4” (default)
Customizable inlet/outlet orientation
Mounting holes adjustable for OEM specifications
Compatible with rack server manifolds and coolant distribution units (CDUs)
The low-profile design of the SP5 CPU Water Block fits within 1U and 2U rack-mounted servers, supporting dense computing environments.
It is widely adopted in data centers, AI/ML clusters, cloud servers, and high-performance computing nodes, where efficient cooling is vital for maintaining stable clock speeds and energy efficiency.
