I've been having some serious overheating issues with my 9800X3D processor. I'm using an H115i Elite Capellix XT AIO cooler and an Asus TUF B650 Plus WiFi motherboard with Windows 11. My idle temperatures are around 45°C, but when I game, they soar to about 70-87°C. During intense loading moments, like kicking off a mission in 'Ready or Not,' my CPU temperature spikes, and my PC shuts down at around 94.88°C. I've already repasted the CPU three times and ensured there's nothing obstructing the cooler block, tightening it as much as I can. I'm looking for advice on how to manage these temperatures better, if there's a way to prevent the shutdowns, or settings I can adjust that might help without sacrificing performance. I've tinkered with the BIOS but reverting to default settings and disabling XMP doesn't seem to help. I'm quite frustrated with this—any suggestions?

If you're gaming on high settings, consider lowering your FPS cap. This can help reduce the load on your CPU and ultimately keep those temperatures down.
Make sure your cooler is mounted correctly. Sometimes it helps to mount it using an 'X' pattern, tightening each corner step by step. This way it ensures even contact with the CPU. And definitely, verify that you're using thermal paste and that it's not dried out or improperly applied.
First things first, check if your BIOS is up to date. An outdated BIOS can sometimes cause weird temperature management. Your CPU tries to protect itself by shutting down at high temps. If updating the BIOS doesn’t help, try adjusting your cooling settings in Corsair iCUE to enhance the cooler's performance.
Also, ensure your AIO pump is functioning correctly. Check that it's circulating properly and that the fans are spinning.
You might also want to consider downclocking or limiting the CPU's performance. While it can feel counterproductive, it might prevent those spikes. A lot of people have found that running their DDR5 RAM at 5600MT/s improved stability on similar setups. Clear the CMOS if all else fails to reset things.
Additionally, check all your power supply connections, especially the 8-pin CPU connector. It's amazing how often this is overlooked!
