Each cooler mounting system is different, but there should always be a good amount of mounting pressure. This is also required for the CPU to make good contact with the pins in the socket.Your pattern looks very good (not talking about the wrinkles, that is just an artifact of the thermal paste moving to fill the voids when the cooler is removed). In a perfect world the contact between the base of the heatsink and the CPU should be so perfect that there is no space for any thermal paste to be in there. The areas with almost no thermal paste are areas with very good contact, that is a good sign, not a bad one. That is how it is supposed to be.There are always areas of high pressure and low pressure. Eventhough it seems that there is a massive difference (due to areas with no thermal paste and other areas with thermal paste), in reality those areas are almost the same. It is extremely hard to manufacture a perfect contact between the heatsink and the CPU. What you are seeing are microscopic gaps. I would consider a problem if there would be no areas with almost no thermal paste (many things could cause that, like not enough mounting pressure or heatsink base not mating the top of the CPU properly due to shape and/or flatness mismatch).I recommend you to watch this video to understand this topic in more detail[MEDIA=youtube]7BMYsMGpyFY[/MEDIA]
