Dynatron S2 Passive 2U Server CPU Heatsink
Passive 2U HeatsinkIntel LGA4677Copper Vapor ChamberSapphire Rapids Xeon
The Dynatron S2 is a passive server CPU heatsink for the Intel Socket FCLGA4677 used by Sapphire Rapids Xeon processors, engineered for 2U (and taller) rackmount chassis. It combines a copper base, vapor chamber and heat pipes with an aluminium fin stack to shed heat using the server’s own front-to-back airflow — no onboard fan. Part number 88885621, it stands 64mm tall and is rated to handle very high-wattage processors. It is built for datacentre and workstation-class dual airflow chassis. Typically in stock with fast delivery across Cyprus.
Compatibility — check before buying:
For the Intel FCLGA4677 (Socket E) platform only, in 2U or taller servers that provide strong front-to-back airflow. As a passive heatsink it has no fan and relies entirely on chassis fans — it is not suitable for a standard desktop tower or any low-airflow case. Ships with E1A and E1B package carriers; the E1C carrier is available on request for certain processors.
Best For
✓2U and taller rackmount servers with high airflow
✓Intel Xeon Scalable Sapphire Rapids (LGA4677) builds
✓Datacentre and high-density compute nodes
✓Systems that cool CPUs via chassis airflow, not onboard fans
✓Workstation-class dual-socket server platforms
✓Replacing or servicing an existing LGA4677 heatsink
Key Features
Passive 2U Design
No onboard fan — the S2 uses the server’s front-to-back airflow, reducing part count and noise sources while fitting neatly into 2U and taller chassis.
Copper Vapor Chamber
A copper base with vapor chamber and heat pipes spreads heat rapidly into the aluminium fin stack, giving the thermal capacity high-wattage Xeons demand.
High Wattage Capacity
Rated to handle up to 490W at 20°C ambient, it is dimensioned for the hottest Sapphire Rapids parts when paired with adequate chassis airflow.
Secure Server Mounting
Uses #8-32 screws at a defined 8 in-lb torque with pre-applied Shin-Etsu 7762-class thermal grease, for consistent, serviceable installation.

Frequently Asked Questions
Does the Dynatron S2 include a fan?
No. It is a passive heatsink that relies on the server’s front-to-back chassis airflow. It is designed for 2U and taller servers, not for low-airflow desktop cases.
Which processors does it fit?
It mounts on the Intel FCLGA4677 (Socket E) platform used by Sapphire Rapids Xeon Scalable processors, with E1A and E1B carriers included.
How much heat can it handle?
It is rated for up to 490W at 20°C ambient. Real-world capacity depends on your chassis airflow and inlet temperature, so pair it with adequate server fans.
Can I use it in a normal PC case?
No. Without its own fan it needs the strong directed airflow of a rackmount server. In a standard tower it would not receive enough airflow to cool a high-TDP Xeon.
Singular Expert Insight
The S2 is the passive route for LGA4677 servers where chassis fans do the work; Dynatron’s active S-series (such as the S5) adds an onboard fan for chassis with weaker airflow. Choose based on your server’s fan wall and 2U clearance. For desktop and tower builds, see the active options in our CPU coolers range instead. When commissioning a dual-socket node, confirm your power supply and airflow are rated for the full CPU load.
Buyer's Guide
Buy it if
You are building or servicing a 2U+ Intel LGA4677 Sapphire Rapids server with strong chassis airflow.
Skip it if
You have a desktop tower or low-airflow case, or a different socket — a passive heatsink needs directed server airflow to work.
Also consider
An active Dynatron S-series heatsink if your chassis airflow is limited, or the correct package carrier for your specific Xeon.
