  • Cools Intel Sapphire Rapids CPUs up to 350 W TDP
  • Fits FCLGA 4677 socket for secure processor mounting
  • Designed for 2U chassis height constraints
  • Active fan assembly handles 550 W maximum heat load

Server cooler for Intel Sapphire Rapids

The Dynatron S5R1 is a 2U active heatsink built for the FCLGA 4677 socket. It supports Intel Sapphire Rapids processors with a thermal design power of up to 350 W. The unit is supplied new and carries the manufacturer part number 277565.

Fits 2U Intel platforms only

This cooler suits administrators deploying high-power Intel chips in 2U rackmount systems. It will not fit 1U chassis or motherboards using a different socket. Buyers who need AM4 support or passive 1U cooling should look at a different part.

350 W TDP on FCLGA 4677

The decisive specification is the 350 W heat dissipation rating on the Intel FCLGA 4677 socket. The manufacturer also lists a 550 W maximum power figure for reference. Confirm your processor TDP and socket before ordering.

Questions about this item

How do I install the Dynatron S5R1 active heatsink onto the FCLGA 4677 socket, and what step is commonly missed?

Align the heatsink mounting holes with the FCLGA 4677 socket retention frame, secure the four captive screws in a diagonal pattern, then connect the PWM fan header to the motherboard; the step often missed is plugging in the fan power cable before closing the chassis.

What maintenance or replacement will the Dynatron S5R1 require over time?

The 277565 fan assembly is the only moving part; plan to clean dust from the fins every 6 to 12 months and replace the fan if bearing noise appears or airflow drops below specification.

At what sustained power level does the Dynatron S5R1 hit its thermal limit first?

The cooler is rated for 350 W continuous dissipation; sustained loads above that level will cause temperatures to rise before the 550 W maximum power threshold is reached.
