Madsupra is absolutely correct.
On an Intel CPU "Cool and Quiet" is called Speedstep, but it does the same thing.
Effectively by putting it to High Performance, you are disabling Speedstep and thus using more power/clock cycles because the CPU can't cycle down.
There is NO need to use High Performance, it is one of the most worst named settings ever. Balanced (or "HP Recommended" in your case, but their the same thing) will give you exactly the same performance, but will also allow the CPU to idle.
In truth, what your seeing isn't the CPU working overtime, it's the fact it can't Idle, so it's being confused, and thinking it must be working hard, and telling Windows this. WIndows doesn't "magically" know what your CPU is doing, it reports what the CPU is telling it.
In truth, it should be called "Use lots of power for no reason" not "High Performance"
Hope it helps
