No black felt tape on fan
Macbook A1181 13 2.0GHz (Intel core duo)
I bought my macbook used in February. I had to open it up to clean it and noticed that it doesn't have the black tape on the grill of the heat sink where it meets the fan. I am about to have to replace the fan, would it be ok to leave it or should I cover it. If I have to cover it what can I use?
