Intel uses a Speed Boost Technology as talked about here:http://www.intel.com/support/processors/corei7/sb/cs-032279.htm
That can allow the processors to boost above their stated max usually for short periods of time [not sure what the limits are].
Oh, and everything should be fine. Especially on new CPUs they have all kinds of thermal, fan and other controls and what not to monitor the CPU and do what is needed to keep it from getting damaged. If this is the auto setting I would really not worry. Only worry if you set it to like extreme performance manually and were to somehow disable it's ability to do the thermal checks and throttle based on those. Otherwise, if you use an application [looks like you are using some intel util] to use what they have there to do adjustments you should be fine as it will always watch over the CPU and it's current health and would usually even warn you if there was a temp or other issue that was starting to cause issues.
