so the 10 degrees difference is no problem? cuz I want to OC it in the future so thats what's worrying me
Temperatures under load that stays below 67.4 celsius is great. Ivy-bridge CPUs Works best under that temperature. At most times your CPU won't even reach that temperature you got now at stock when you overclock it. There almost aren't any apps that makes your CPU go to 100% usage in real World usage right now, so you'll be fine.
