The fans are working fine, although maybe not as fast as before, and the top tasks are java as expected.

There is something here that is new behavior, but I can't quite pin what it is. Either:

1. The older kernels did not protect the CPU from overheating.
2. The older kernels used a different form of thermal protection such as reducing the clock frequency.
3. My system is suddenly running the cpu hotter.

I do wonder why the idle injection has to max out at 50%, instead of slowly ramping up until the temperature goes below the threshold.
