Aio placement
Aio placement
your front mount works well—it pulls in fresh air, while trapping it at the top of your radiator rather than inside the pump. Many people place it there too; it depends on the fit. You’ll need equal fans for intake and exhaust to maintain proper airflow. As you do now, flipping the AIO front-on will cause air to collect in both the pump and radiator top, shortening its lifespan since pumps don’t handle dry operation well.
Your radiator is drawing cooler air from outside, which is a positive sign. For rotation, I install them in any orientation during assembly—it won’t cause issues since air will naturally flow back up. If you rotate the tubes at the bottom of the radiator (which is fine as air will redirect), it might affect your GPU. Alternatively, placing it at the top with fans moving warm air out could help. You should experiment to see which setup gives better cooling, and adding fans at the front of the case would be wise.
