Water block Alphacool 13498 acetale rame nero argento 75,5 x 118,5 x 20,5 mm

The Alphacool ES Jet water block (Alphacool 13498) is a compact, high-capacity CPU cooler developed for powerful processors on Intel LGA 4677 sockets used in server and workstation systems. The cooler combines a nickel-plated copper construction with an acetal top and uses an innovative four-nozzle distribution system that directs coolant across the base to cover all processor cores. The design supports reliable heat dissipation up to 800 W and includes Alphacool Subzero thermal paste with a thermal conductivity of 16 W/mK.

Advantages

The integrated four-nozzle arrangement provides targeted and even coolant distribution over large processor cores, improving cooling precision compared with single-nozzle designs. The nickel-plated copper base offers high thermal conductivity, making it more effective than aluminum for heavy-load server and workstation applications. The cooler is manufactured to be compact and low-profile with side-mounted connections to facilitate installation in server racks. The included Subzero thermal grease is electrically non-conductive and optimized for high contact pressures while remaining workable due to its viscosity.

Suitable for

• Server and workstation CPUs on Intel LGA 4677
• High-performance systems that require up to 800 W heat dissipation
• Compact rack-mounted builds where side connections are advantageous
• Custom liquid-cooling loops using nickel-plated copper water blocks

How to use

Mount the water block onto an Intel LGA 4677 CPU following the server or motherboard manufacturer’s mounting instructions and Alphacool’s torque recommendations where provided. Apply the included Alphacool Subzero thermal paste to the CPU contact surface in a thin, even layer before fitting the block to ensure optimal thermal transfer. Connect the block to your liquid-cooling loop using appropriate fittings on the side-mounted ports, and verify flow and leak-free operation before full system use.

Recommendations

For best results in server or workstation environments, use corrosion-inhibiting coolant compatible with nickel-plated copper, maintain regular loop maintenance, and ensure sufficient flow rate to benefit fully from the four-nozzle distribution. Verify clearance in rack-mounted systems and prefer side-mounted fittings to simplify installation.
