cpu-speed

I am running Windows 8 Pro on an Apple MacBook Pro 9,1 Mid 2012 15 inch non retina. It has a Core i7-3720 QM CPU @ 2.6 GHz. For the past few days, I have noticed that it is constantly running at max speed which is 2.59 GHz. Before, it used to run at 1.5 - 1.8 GHz on normal usage. And, the weirder thing is that CPU usage is minimal.

So, what is the reason for this? And is it harmful?
