CPU air cooler kit FUJITSU S26361-F4051-L820 for 2nd processor, compatible server cooling module

Replacement CPU air cooler kit FUJITSU designed for installation as a second processor cooling module in compatible Fujitsu servers. This kit provides targeted airflow and improved heat dissipation for an additional CPU, helping to maintain safe operating temperatures during sustained load and supporting stable performance and component longevity. The module is intended for system maintenance, upgrades, or when a server configuration requires an extra dedicated cooler for a second processor.

Advantages

The kit delivers focused cooling to the secondary CPU position, reducing thermal stress on the processor and nearby components. It is engineered to fit compatible Fujitsu server layouts, enabling straightforward replacement or addition without major chassis modifications. By restoring or enhancing airflow, the cooler helps prevent thermal throttling during high-utilization periods and contributes to predictable system behavior under load. The design supports continuous operation typical for datacenter environments.

Suitable for

• Installation as a secondary CPU cooler in compatible Fujitsu rack or tower servers
• Server maintenance where an extra cooling module is required after CPU upgrade or replacement
• Preventing thermal throttling in dual-processor configurations under sustained workload
• Replacing a failed or degraded second-CPU cooling module to restore manufacturer-recommended airflow

Key specifications

• Form factor: dedicated air-cooling module intended for secondary CPU position in compatible Fujitsu server chassis
• Cooling method: active air cooling with integrated fan(s) and heatsink assembly designed for server airflow channels
• Compatibility: specific to Fujitsu server models that accept a dedicated second-processor cooler (verify chassis and CPU socket layout)
• Purpose: replacement or additional cooling for a second processor to maintain operating temperatures under load
• Mounting: designed for tool-assisted or tool-free installation according to server manufacturer's service instructions

How to use

Power down the server, disconnect power sources, and follow antistatic handling procedures before beginning installation. Remove the access panel and locate the secondary CPU area following the server service manual. Remove the existing cooling module if present, clean the processor surface and surrounding area of old thermal interface material, and apply new thermal compound per the manufacturer's guidance. Position the replacement cooler kit onto the secondary CPU area, secure mounting points according to the chassis instructions, and reconnect any fan or sensor connectors to the system board. Reassemble the chassis, restore power, and verify that the system recognizes the fan(s) and reports normal operating temperatures in system management utilities.

Recommendations

Use only in servers verified as compatible with this Fujitsu second-processor cooling module. Follow Fujitsu service documentation for torque specifications, thermal compound type, and fan connector locations. After installation, monitor system temperatures and fan speed through server management tools during a controlled stress period to confirm effective cooling. Regularly inspect and clean airflow paths and replace the module if fan noise, reduced airflow, or elevated temperatures indicate degradation.
