Server CPU Heatsink for X3550 and X3650

This heatsink fits IBM System x3550 M2, M3 and x3650 M2, M3 servers. It mounts directly onto the processor socket to dissipate heat in 1U and 2U rack chassis. The part is supplied new and matches FRU 49Y4820 and part number 49Y5341. System administrators maintaining these platforms use it to replace a worn or missing cooler.

Direct replacement for original FRU cooler

It replaces the factory heatsink shipped with the listed servers without modification. The jump is worth it when the original cooler is damaged, lost during a board swap, or shows degraded thermal performance. Technicians installing a spare processor in a cold-spare chassis also need this matching cooler. It is not for builders assembling white-box servers or anyone using non-IBM motherboards.

Limited to specific IBM System x models

The mounting pattern and airflow shroud align only with the X3550 M2, M3 and X3650 M2, M3 families. It cannot be adapted to other form factors or processor sockets. Buyers must verify the exact server model and FRU number before ordering because no universal bracket is included.
