Probably some background process occurring, even windows updates downloading will force cpu's to boost for some weird reason.

As long as the actual core usage isn't high I wouldn't worry, its hardly going to affect temps etc in the slightest.

But the processor runs at ~ 4ghz all the time even when everything is turned off. Temperatures are ok around 36C
