Dynatron S5R1 4677 2U Active Cooler for Intel 4677 up to 550W

Dynatron S5R1 4677 — Powerful Server Cooler

Cooling powerful server processors requires a precise and reliable solution that can handle extreme loads. The Dynatron S5R1 is an active cooler designed for Intel processors with the FCLGA 4677 socket, providing exceptional cooling performance up to 550 W TDP, which is crucial for servers with high computing density. With its compact dimensions of 118 x 82 x 67 mm, it is ideal for deployment in 2U server environments and above. This model stands out with a combination of advanced materials, such as 5 heatpipes and aluminum fins, which effectively dissipate heat and keep the processor in a safe temperature zone.

Performance and cooling efficiency

The Dynatron S5R1 is equipped with a 60 x 60 x 25 mm fan that offers three power modes with rotation speeds from 2300 rpm at low load to 11,000 rpm at maximum load. This variability allows for an optimal balance between cooling performance and noise. The fan achieves an air flow of up to 58.31 CFM, which ensures reliable cooling even during intensive operation. With a noise level of 25.8 dBA at low load, it is also suitable for noise-sensitive environments.

Reliability and long life

The cooler uses Double Ball bearings, which are known for their durability and long life. At a normal operating temperature of 40 °C, the Dynatron S5R1 guarantees a lifespan of up to 70,000 hours, making it an ideal choice for continuous server operation. In addition, the cooler is equipped with Shin-Etsu 7762 thermal paste or equivalent, which ensures perfect heat transfer between the cooler base and the processor.
