⚙️ Fit Notes

• Match your original heatsink / fan assembly part number whenever possible
• Confirm your motherboard uses Intel Socket LGA1366 / Socket B
• Confirm your system supports this active Intel heatsink and fan assembly style
• Confirm your motherboard has a compatible 4-pin CPU fan header
• Confirm the heatsink mounting pattern, surrounding component clearance, fan height, and chassis airflow before ordering
• This cooler is for compatible LGA1366 desktop / workstation-style installations and may not replace proprietary server heatsinks
• Many rackmount servers and OEM workstations use chassis-specific passive heatsinks, ducted airflow, screw-down heatsinks, or proprietary fan assemblies
• Fresh thermal compound is recommended during installation: Shin-Etsu G751 Thermal Grease
• This is not compatible with LGA775, LGA1150, LGA1151, LGA1155, LGA1156, LGA2011, LGA2011-3, LGA2066, LGA3647, AMD sockets, or other non-LGA1366 platforms
• If any existing thermal compound is damaged, dried, contaminated, or removed, clean the CPU/heatsink surface and apply fresh thermal compound before installation
