It should be fine, for what its worth my GPU cooler was damaged in shipping and it has been perfect in actual use, it is a second hand R9 290 so it has put upnwith this for years.
I would think as long as there are spaces between the fins, and the vapor chambers arent kinked or bent closed the cooler would still be as effective. Theoretically…???
If you don’t see a hole and it isn’t spraydnlling shit all over when you put the eatplate on something warm then eh you’re fine don’t worry about it
