Temperature at 90-93°C for this model
You're experiencing high temperatures and occasional overheat warnings on your Ryzen 9 5900X with the MSI Mag 240R AIO case. The CPU temps spike to 93°C during idle and 80°C under load, even after the latest BIOS update. It seems the AIO isn't providing enough cooling for your specific setup. Consider upgrading to a better cooling solution like a liquid cooler or switching to a more efficient case with higher airflow.
It seems the setup doesn’t have enough front airflow. Check if moving the PC outside the case helps temperatures. A slight improvement might mean the cooling fan isn’t working properly.
I own seven 120mm fans plus two 120mm for the AIO. The airflow works well and you can even sense the cool air at the back and upper fans. Three fans in front use a pull setup, two AIO fans are mounted sideways, one fan has a pull configuration at the bottom, two have push setups on top plus one at the back.

More fans don't automatically mean better performance. Air is entering from various angles, likely creating turbulence that blocks proper flow to your parts. Outgoing cold air doesn't guarantee success; it might indicate hot air is trapped while fresh air escapes prematurely. If the room temperature is extremely low, you probably won’t notice overheating issues. Ideally, the system should be warm or hot coming out of the case, showing active cooling. The AIO offers only average performance and a modest 240mm size. A better air cooler would likely outperform it. The case's thermal design is subpar unless the front panel cover is removed, which then provides minimal airflow through the side vents—unless you're using powerful fans.
