Cleaning the fan -- is this lint or foam?
I was cleaning the fan of my computer this evening. When I took the fan out, some black stuff came out from the space where the fan meets the heat sink that looks like it is either lint or foam. Here are pictures:
Is this foam? Is there supposed to be foam there? (I can't tell from the repair/tear down pictures.) If so, where can I get replacement foam? It tore apart as I took it out.
Is this a good question?
