Triangular metal tab under heat sink broke. Should I be worried?

I have a ps4 normal (1100) series. I was cleaning the ps4 and as I reached the plate under the heatsink and was cleaning it I accidentally disconnected one of the triangle shaped metal tabs on the back. The tab is now not reattaching and is also in worse condition than the others. Should I be worried?

Do I have to reattach it and if so how. Please help.

PS - I noticed the tab is supposed to touch some golden coloured squares on the motherboard and there are a lot of these tabs on the heatsink if that helps.
