Qooling quiz

[MrSeanKon]

First system's data:
Frequency1=2.9GHz, Vcore1=1.45Volts and temperature at full load 43C.
For frequency2=3GHz, Vcore2=1.53Volts the temperature is 47C.

Second system (similarly):
Frequency1=2.5GHz, Vcore1=1.4Volts, temperature1=36C.
Frequency2=2.7GHz, Vcore2=1.6Volts, temperature2=42C.

Which system has better cooling?

 

[MrSeanKon]

You are right but I would like to know your thoughts.
Why you chose the second system?

 

[MrSeanKon]

We assume that both systems are at full load and same ambient temperature.
But this (the ambient temperature) does not matter in internals.
