Thermal rules

This topic provides thermal rules for the server.

Abbreviations used in tables below are defined as follows:
  • Max.Temp.: Maximum ambient temperature at sea level

  • FIO = riser 5 + front OCP

  • S/S: SAS/SATA

  • Any: AnyBay

  • S: standard

  • P: performance

  • A: advanced

  • NA: not applicable

  • Y: yes

  • Y* in the Support middle bays or Support rear bays column: yes (when no Gen5 7.68 TB or larger capacity NVMe drive is installed)

  • Y1 in the Support DIMMs >= 96 GB column: yes (except ThinkSystem 96GB TruDDR5 4800MHz (2Rx4) RDIMM-A and ThinkSystem 128GB TruDDR5 4800MHz (4Rx4) 3DS RDIMM-A v1)

  • Y2 in the Support DIMMs >= 96 GB column: yes (except ThinkSystem 128GB TruDDR5 4800MHz (4Rx4) 3DS RDIMM-A v1)

  • N: no

Processor groups are defined as follows:
  • Group B: 200 W ≤ cTDP ≤ 240 W

  • Group A: 240 W < cTDP ≤ 300 W

  • Group E: 320 W ≤ cTDP ≤ 400 W
