Thermal rules for the server with 9005 series processors
This topic provides thermal rules for the server with 9005 series processors.
Standard configurations: server models with front drive bays only
- Thermal rules for DIMMs
Thermal rules for server models installed with PCIe/OCP adapters (≥ 100 GB)
Fan locations and supported quantity for different configurations
The maximum supported DIMM quantity is 12.
cTDP is short for Configurable Thermal Design Power. It refers to the maximum supported power of a processor.
System performance may be impacted when the operating temperature is above 35 °C.
- When a 10 x 2.5" AnyBay backplane is used, only the following two configurations support closed loop heat sink:
10 x 2.5" NVMe (Gen 4)
8 x 2.5" NVMe (Gen 5)
Group B: 200 W ≤ cTDP ≤ 240 W
Group A: 240 W < cTDP ≤ 300 W
Group E: 320 W ≤ cTDP ≤ 400 W
Heat sink types and fan types in the tables are abbreviated as follows:
Air cooling heat sink: AC
Closed loop heat sink: CL
Performance fan: P
Standard fan: S
Standard configurations: server models with front drive bays only
This section provides thermal information for server models with front drive bays only.

Storage configurations: server models with rear bays
This section provides thermal information for the storage configuration when rear drives (except 7mm drives) are installed.
Front bays | Max. Ambient Temp. (at sea level) | Processor group | Heat sink | Fan type |

25°C | E (except 9575F) | AC | P |
To support rear 2 x 2.5" SAS/SATA or NVMe (U.2/U.3) drives, the following conditions need to be met:
Gen 4 low-profile riser installed in Riser 1
No Riser 2 installed
No 7mm drives
No PCIe adapter installed in slot 2 and slot 3
10 x 2.5" AnyBay front backplanes support rear NVMe (U.2/U.3) drives but do not support rear SAS/SATA drives.
GPU configurations: server models with GPU adapters
This section provides thermal information for the GPU configuration.
- Low-profile, half-length, single-wide:
NVIDIA® A2
NVIDIA® L4
All GPU configurations require performance fans.
