Hello, im new to this forum sorry if i am posting in the wrong section i couldn't find a heatsink question. I opened up my laptop and i notice this weird type of tape that is used to tape the heatsink and fan together. I wanted to know if any of you guys know what type of tape this is it kinda of has a rough surface and its black. And if i cant find the type what alternative tape can i use?should it be non conductive?thermal?both?
