Issues with GPU Temp in My New PC Build

I just built my first PC, and I'm running into some heat issues. My setup includes an RX 7900 XT graphics card, and while playing Clair Obscur: Expedition 33 on Epic settings, my GPU temps are reaching about 91°C. I've got an Antec CX500M case with two intake fans on the side/front and three exhaust fans (two on the top and one at the rear). I'm wondering if my cooling setup is the problem. My CPU also runs at around 80°C during gameplay, which I've read is normal, while it's around 43-51°C at idle. Can anyone provide some advice?
