Temperatures too cold?

Hello! I am new to the OC world. I just got a new Cooler Master Hyper TX3 for my CPU because the stock one just wasn't cutting it and the fan made a weird squealing sound. Anyway, after installing, I posted a screenshot of my temps in CoreTemp. I was kind of shocked because it was saying it was as low as 11-13 celsius. Isn't that bad? I also took readings a little bit later with OpenHardware and the reading was a bit different, but still low. Does this mean I HAVE to OC my processor?

Dont worry about idle temps. What you need to be concerned with are load temps. As long as your CPU Core temp remains below 55C is pretty much sure to be stable. We start to get concerned around 60C on AMD chips, but mild overclocks tend to still be stable even at high temps. For example my wifes rig has been running her 8120 @ 3.2Ghz all week without a crash at 68C but its barely over stock speed so meh.
