I just received the pi 4 starter kit. As I was putting it together, I got some dust on the thermal tape that connects the board to the case/raspberry pi heat sink (the dust was on the case side, and literally only a few tiny specs). Will this pose any issues and should I replace it or will it be ok?
Dust on the thermal tape shouldn't pose any issues, as long as it's just a few tiny specs. If you are still concerned, you can replace the tape, but it's not necessary.
