1. They are good, if we are talking maximum Core temps on the 4 cores....
...if it's package temp, then not really meaningful
2. They are good if you used something like Intel XTU or ROG Real Bench to establish load conditions
... if it's a game or program, then again, not really meaningful.
3. 25C is good if ambient air temps are 21-22C...
... if ambient was 60F (15.5C), not really meaningful.
