NOTE:
When the 80 GB GPUs are installed, the iDRAC sets the thermal warning threshold to 28° C instead of the normal
38° C.
NOTE:
If System Board Inlet Temp reaches 28° C - 32° C, a warning message is logged. It is possible the GPUs may lower
power consumption to avoid thermal damage. This results in lower GPU performance.
