I recently built my new PC and I'm having a strange issue with the idle temperatures of my 9800X3D CPU. Most users report idle temps ranging from 35-50°C depending on their cooling setup, but mine is idling at a higher range of 55-57°C, which feels abnormal given my cooling system. I'm using a 360 AIO, and here are the specs: 9800X3D, Arctic Liquid Freezer III 360, 5070 Ti Vanguard, MSI B850 EDGE TI motherboard, Montech KING 95 case, and my fans are configured for optimal airflow. I've tried various tuning options like adjusting the PBO curve, enabling/disabling global c-states, and testing with different power plans. Despite these efforts, even with full fan speeds, I'm barely hitting the lower 54°C while idle. It's worth noting that my load temps during stress tests are reasonable and stable. However, I'm worried about the high idle temps, especially since I invested over $3000 into this build. Any ideas on why this might be happening?

Honestly, idle temperatures are usually not something to lose sleep over. As long as your load temps are in check, you should be fine. Some CPUs just run hotter when they're idle. It could be airflow issues in your setup too, especially if the intake is going over the GPU first before reaching the CPU cooler.
I get that, but it still seems odd to me. When things don’t perform as they should, it makes sense to dig deeper, right?
