I recently purchased a custom-built PC from someone on Facebook Marketplace, and I've noticed that my GPU temperatures can reach 84 degrees Celsius while I'm gaming. While that's not the worst, it's still concerning. I just got an electronic air duster from Amazon, but I'm not sure if the fan setup in the case is optimal. I would really appreciate any advice on how to arrange the fans for better airflow. Here are some photos for reference: https://imgur.com/a/dmKLmC0 and https://imgur.com/a/WBkkIn3.

I suggest setting the bottom three fans to intake for cooler air, having the two radiator fans also act as intakes, and leaving one fan at the back as an exhaust. This setup should help to improve airflow and remove heat more efficiently.

You might want to consider moving the AIO cooler to the top as an exhaust instead. The bottom fans can be flipped to act as intakes, while keeping the back fan as exhaust. Just remember that the GPU could be part of the overheating issue too.
