This has been a Raspberry3 (still, and for a while, Unobtainium). - When using this heatsink and ever have the need for heat sink removal, you'll face a situation like this. Use other heat sinks, or just don't ever remove the attached one. Or replace the original gap pad and use another one w/ less or none adhesive power.
