Is the Asus RX 480 8GB OC video card heating up?

Question

Video cards

Hello dear friends. I’ll start from the beginning, I decided to invest in mining with my friends, ordered 8 video cards, assembled 2 farms and everything was flying fine until I broke one wing of the video card cooler. The cooler continued to work after 2 days, we noticed that this video card was heating up, pulled out the video card, glued the wing thinking that everything would return as it was, but the miracle did not happen and the video card continued to heat up to 85-90 degrees, although during mining the normal temperature reaches a maximum of 60-65 degrees . I decided to change the thermal paste on the video card processor (I found a syringe of Chinese thermal paste (I don’t know the expiration date)) I smeared it, but I didn’t see the difference. Help what you can. What do I need to do next?
And what is the danger of unbalancing one of the video card coolers?
