Been noticing this for a bit now. Not sure if started with the update to 5.1 or not. It happened before, started again. Mention because noticing glitches and such. Like when running Logos, machine went to sleep, and fans started blowing like proc was going crazy. Logos was using it up. Will log next time.
EDIT: This could also be due to the Mac 10.8.5 update. I didn't do the combo updater.
