Product Details

Intel LGA4677 Description:
The EagleStream platform is the latest generation server platform launched by Intel, aimed at providing high-performance computing and data processing capabilities. The platform not only innovates in technology, but also widely recognizes and applies the LGA4677 CPU, which adopts the new 7-nanometer technology. The EagleStream platform adopts advanced technology and design to provide excellent performance and efficiency. It supports multi-channel memory and high-speed data transfer, which can meet the stringent requirements of high-performance computing and data centers. In addition, the platform also supports AI and machine learning applications, further expanding its application scope in the fields of data processing and analysis.
LGA4677 CPU heat sink is designed for Intel LGA4677 socket, this CPU heat sink cooler consists of copper stamped zipper fin, copper vapor chamber. Stamped zipper fin stack is a critical component due to it has great heat dissipation performance. A stamped zipper fin stack is manufactured by using a stamping process to punch the copper sheets into designed shape from a tooling die. The fin stack are manufactured to create interlocking fins by stamping process, the copper zipper fin can be manufactured with a range of geometrics and thickness.


The LGA4677 1U Standard CPU heatsink is design for the intel eagle stream platform series processors ,thermal design power is 205W for 1U server air cooling . The heatsink use Aluminum base, copper plate, aluminum zipper fin and copper pipe ,and assembled together by reflow soldering process. Heatsink hardware adopts the intel standard peek nut to provide 32lbf lock force for cpu assembly , and the thermal interface material is Shin-ETSU,7921 or DOW CORNING,TC-5888. And the indicator label attached on the heatsink surface helps customer better underdtand the lock and unlock steps of the hardware during CPU installation and disassemble.
For all the thermal heatsinks with heatpipe or vaporchamber, Sinda Thermal require 100% online thermal test before ship to customer. Therefore , a golden sample or limit sample will be needed for every production performance verification , the themral spec is defined and used as the reference data to make use the stable performance heatsink production before shipping.

Custom Thermal Solution:
For those high performance requirement customer, the heatsink material, size, fin thickness,fin pitch parameters can be customized based on customer's needs.
Sinda Thermal is a manufacturer specializing in CNC machining ,stamping and thermal components related products. We make all kinds of metal products and radiators, which are widely used in server,computer, new energy batteries, new energy vehicles, communication equipment, household appliances, medical equipment, military industry and other fields.
