EGX-MXM-RTX5000
1.7 Thermal Policy
The GPU core clock throttles at temperatures (T
J
) past the thresh-
olds shown with the behaviors as listed. Thermal throttling ensures
that the highest temperature on the die does not exceed the sense
temperature for prolonged periods of time.

Parameter Value Units
Thermal Resistance (Junction to Case, RJC) 0.014 °C/W
Thermal Resistance (Junction to PCB Board, RJB) 0.64 °C/W
GPU Maximum Operating Temperature1 89 °C
GPU Slowdown Temperature (THERM_ALERT)2 97.5 °C
GPU Shutdown Temperature (OVERT)3 102.5 °C
NOTE: NOTE:
X
Max.GPU operating temperature is the maximum at
which the GPU is guaranteed to operate at target perfor-
mance (base clock) under total board power level
X
THERM_ALERT generates a 50% (÷2) hardware clock
slowdown.
X
OVERT generates a 87.5% (÷8) hardware clock slow-
down
