Hey everyone! I just put together my first PC, and I'm running into some issues with the temperature of my GPU. I'm using an RX 7900 XT, and during intense gaming sessions, like playing Clair Obscur: Expedition 33 on Epic settings, my GPU climbs to about 91°C. That seems quite high to me, so I'm concerned there might be an issue with my cooling setup.
My case is an Antec CX500M, equipped with two intake fans at the side/front, two exhaust fans on the top, and one exhaust at the back.
In terms of CPU temperatures, I'm seeing around 80°C during max settings, which I've read is fairly normal. Idle temps for the CPU are between 43-51°C.
I'd appreciate any advice or insights you might have!

Looking at the Antec CX500M, it's capable of taking 3x120mm fans at the bottom. If you could manage it, add in a couple of bottom fans to increase airflow directly to your GPU! But from what you've described, check if there are really no mounting points since the bottom area might be limited.
Generally, to achieve optimal cooling, it's recommended to have more intake fans than exhaust. However, hitting 90°C could indicate that the GPU cooler might not be functioning properly, or there could be a sensor issue. Double-check your fan orientations and try temporarily disabling 2 of your exhaust fans to see if that helps. If temperatures don't drop, focus on checking the GPU cooler.
It sounds like your cooling setup might need a little tweaking. Fish tank-style cases can be tricky for airflow, and adding a third fan might not make a significant difference. Have you considered undervolting your GPU? That could lower the temperatures more effectively than just adding fans. Also, applying frame caps might help with thermals too.
I get what you're saying about the unbalanced intake and exhaust. It's crucial for the cool air to flow properly to the hardware. As for undervolting, start with small increments—try around 10-15% and see how the temperatures respond. Always monitor your GPU while doing this to avoid any potential damage.
