I'm curious about my recent experience with cooling configurations in my PC. I was always advised to have more exhaust than intake, and to set up my AIO cooler at the top for exhaust. I followed that advice but ended up with a hot CPU and coolant temperatures around 50-55°C under load, even with my fans at full speed. Eventually, I switched my setup to have the AIO as an intake at the top, with six exhaust fans elsewhere. To my surprise, my CPU temps dropped significantly, and coolant temps are now in the 30s. Why did this happen? Is there something counterintuitive about cooling setups?

It really depends on your case and environment. Having your AIO set as an intake is often better for CPU temps since it pulls in cooler air from outside. The downside, though, is that you're pushing hot air back into the case. Typically, the AIO should be at the top to let hot air escape easily. But hey, if your setup works better this way, then that's what matters! Just keep an eye on your GPU temps, as this configuration might limit airflow to it. If it’s performing fine, don’t change it just for the rules! Also, consider side-mounted options for fresh air to the GPU.
Honestly, 50-55°C under load isn’t bad for a CPU. Most CPUs are safe under 80°C. The AIO is usually recommended as exhaust to remove hot air effectively since heat rises. Setting intake at the front or sides, and exhaust at the back or top can balance things out. Just remember, your cooling setup should be tailored to your unique build.
I think you meant coolant, not CPU temps! It’s critical to keep coolant under 60°C to avoid damage.
