I think there's something strange going on with the CPU temperature values in the graph.
1) Are you using Fahrenheit for the temperature deltas? :-O
2) Or the values are not actually "over ambient" but actual temperatures. I find it difficult to believe that you would be running the CPU at up to 119°C (assuming ambient of about 20°C)...
3) Or maybe your ambient is close to 0°C?
If using °F, could you please label it as such, and add another graph with Celsius/Kelvin? Temperature differences in °F are pretty much impossible to grasp for most of the World unless you do the math for each value.
