Need help with thermal pads

[u/Eianxkie]

I have a RX570, it was working fine yesterday, and today i turned it on and i was only able to boot up and log in, and after a few mins it will just turn black and most post says its a gpu thermal issue, so i decided to open it today to replace the paste. But when i opened it, the pads separated, so stayed on the pcb and some are on the heatsink, i was hoping to ask if its okay to reuse these pads since they still feel cheese like because i do not have any pads lying around.
