My system uses an RTX 3080 Ti ASUS TUF, Ryzen 7 9800X3D, Gigabyte B650 UD AX motherboard, 850W power supply, dual-fan air cooler, and an Antec P101 Silent case. The PC has always felt unusually hot, especially after gaming. I recently repasted the GPU because it was overheating and crashing, which solved the crashes, but the case and exhaust air still get very warm.
After about 20 minutes of normal Battlefield 6 gameplay at 1440p on low settings, HWiNFO recorded a CPU maximum of 86°C and average of 78°C at roughly 73W, GPU core at 61°C, GPU hotspot at 82°C, GPU memory at 92°C, chipset at 77°C, NVMe drive at 70°C, and a motherboard/system temperature of 41°C. The GPU was drawing around 335W, while the 12V rail remained steady at 11.95V.
I expected the 9800X3D to stay closer to 65–70°C while gaming, so I'm wondering whether 86°C is abnormal, whether my CPU cooler may be installed incorrectly, or whether the restricted airflow from this quiet case is causing the components to heat up. Opening the side panel lowered temperatures by about 15°C, but I would prefer to keep the case closed. Are these temperatures safe, and what should I change first?

The CPU temperature itself is not immediately dangerous. Ryzen 7000 and 9000 chips are designed to boost aggressively until they approach their thermal limits, so 86°C during gaming is generally safe. The GPU core and hotspot temperatures also look reasonable for a card using roughly 335W. A lower temperature would be nicer, but these numbers alone do not indicate a failing CPU cooler.
A warm exhaust is expected: the heat produced by the CPU and GPU has to leave somewhere. Better cooling does not make the exhaust cold; it transfers heat away from the components and gets it out of the case more efficiently. The chipset at 77°C and NVMe at 70°C are more suggestive of poor internal airflow than the CPU and GPU readings. Improving intake airflow should help those temperatures too.
The case is probably the biggest factor here. Silent cases with a closed front panel often restrict intake airflow. A 15°C drop with the side panel open is strong evidence that the components are being starved for fresh air. Check that the front filters and fans are clean, confirm the intake fans are actually running in the correct direction, and use a more aggressive intake and exhaust fan curve. If possible, adding stronger front intake fans or removing/replacing the restrictive front panel would help while keeping the side panel closed.
That makes sense. I was hoping to keep the case completely closed, but the side-panel test dropping temperatures by about 15°C does point to an airflow problem.
These readings were from normal Battlefield 6 gameplay at 1440p on low settings rather than a synthetic stress test. The CPU and GPU temperatures seem acceptable for that workload, but the chipset and SSD still make improving case airflow worthwhile.
