I had to switch motherboards, and when I removed the stock Intel heatsink, the brown/black CPU cover plate came off with it. I went ahead and installed the CPU and heatsink on the new MB, making sure it was oriented in the same way (I could tell by the "thermal glue?" indentions how it was oriented). My CPU temp is always 32-33C, so I am not too worried. But... could I have scraped the cover off the heatsink, applied a little thermal paste to the silver top of the CPU, attached the heat sink, and been OK? What type of non-drying thermal paste is recommended?
