Help Cpu Temp Rise Up After Using Asus Turbo Key

I tried to used turbo key 2 days ago, before activating Turbo Key, my cpu full load temp was 49C, then I turned Turbo Key on, and it rised up to 68C! OF my fear on burning my C2D e7500, I uninstalled Turbo KEy, but then, my cpu is still running on 68C on full load, how to switch back to my previous temp?
