Thermal rules for server with DWCM
This topic provides thermal rules for the server with 9004 series processors and a Direct Water Cooling Module (DWCM).
- 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) 
- N: no 
- 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. 
 
Standard configurations
