I have a MacBook Pro 15" - Model A1226 (Santa Rosa, circa 2007). I need to replace my right fan. AppleCare just expired (of course). But replacing the fan should be pretty easy, I think. The only question is about the tape securing the fan to the heatsink. On the old fan it looks like electrical tape, but on the "sticky" side, it looks like there is a bit of copper (?) in the middle. So my assumption is that regular old electrical tape is not appropriate, but some special kind of electrical tape. What type of tape is that? Thanks.
