Hey guys, I went to install my heatsink/fan on my new motherboard and there's an interesting black layer that's under the socket where my CPU is resting blocking all 4 holes. It might just be something that tears easily but I don't want to risk it and can't find anything about it in my manual or on any sites/comments about the product. I've installed a few fans before and have never encountered it. What is it and how am I supposed to install my fan?
