CPU Frequency running at max

With Beta 15, may have been in 14 as well, I have noticed that my CPU Frequency runs at max speed on my laptop when sitting idle. The CPU load is only 8%. The frequency will run at 4.3GHZ. Other applications will run much lower until thy are doing something. I notice this on my laptop because it triggers the cooling fan to on full the entire time I have scrivener open.

On my desktop computer it raises the CPU temp by 8 to 12 c. Again just when sitting idle.

Has anyone else noticed this happening?

Some third party apps like Norton might be optimizing your computer when idle. It is definitely not Scrivener.
