Thermal rules for server without DWCM

This topic provides thermal rules for the server with 9004 series processors and without a Direct Water Cooling Module (DWCM).

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 or no Gen4 P5336 15.36 TB/30.72 TB/61.44 TB NVMe drive is installed)
Y¹ 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:

Note

For 9184X or 9384X in UEFI Maximum Performance Mode, the processor temperature may reach 95°C in all configurations, and the processor frequency will be impacted but still meets AMD specifications.
ThinkSystem NVIDIA BlueField-3 VPI QSFP112 2P 200G PCIe Gen5 x16 is supported under the following conditions:
- The ambient temperature is 25°C or lower.
- The processor TDP is less than or equal to 300 W.
- The GPU air baffle and performance fans are used.
- The server is not equipped with 24 x 2.5", 16 x 2.5" + FIO, or 12 x 3.5" front drive bays.
Performance fans are needed for all GPU configurations.
The GPU air baffle is needed in configurations that include adapters with power greater than 75 W. No air baffle is needed in configurations with middle drive bays.

Standard configurations

This section provides thermal information for standard configurations.

Note

When a part with active optical cable (AOC) is installed and the rate of the part is greater than 25 GB, the ambient temperature must be limited to 30°C or lower.
When the following parts are installed, the ambient temperature must be limited to 35°C or lower.
- Broadcom 57416 10GBASE-T 2-port OCP
- Broadcom 57454 10GBASE-T 4-port OCP
- Network interface cards (NICs) at a rate greater than or equal to 100 GB
- Parts with AOC and at the rate of 25 GB
In standard configurations, ThinkSystem 256GB TruDDR5 4800MHz (8Rx4) 3DS RDIMM-A v1 is supported only on servers with standard heat sinks at a maximum temperature of 25°C.
