I think this is what is called the Setting of TIM, when the CPU heats the Copper would expand and  the thermal Interface Material creeps inside the small cracks and mircroscopic scratches of both IHS and HSF, this takes some time to completely set, the result is even lower temps. if you dont care about the warrenty of your CPU and if you are in to a lot of over clocking I cannot Stress more that U MUST LAP your CPU and HSF.Heres a screen shot I have taken Today while running OCCT CPU test for 30Minutes.<img src="http://farm4.static.flickr.com/3237/2795096933_089f5ed866_o.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></blockquote>
