'''If you losend or removed the heat sink you must replace the thermal paste.''' ''Arctic Silver works, and there's instructions on [http://www.ifixit.com/Guide/Repair/Installing-Computer-Thermal-Paste/744/1|this site] about how to replace the paste.'' '''The foil tape is not that significant'''...'' you could probably find some foil tape at an electronics or hardware store.'' Good Luck, N.
