CPU overheating
CPU overheating
A few observations came to mind. If you see the exhaust getting very hot, it likely means the cooler is functioning properly. Your GPU is expelling warm air directly into the CPU cooler 5900x, which isn’t the hottest components available right now. Still, I think a single tower setup would be a bit insufficient.
I suggest considering the options carefully and choosing what best fits your needs.
Confirm your mounting pressure and ensure you applied sufficient thermal paste. Are you comfortable removing the CPU cooler to view the paste on the CPU?
Here are some alternatives you could try:
1. Set the rear fan as the intake, reverse the CPU cooler’s airflow, and direct one front intake fan upward as an exhaust—ideally the top one.
2. Rotate the entire CPU cooler 90 degrees to the right, allowing better air circulation toward the top. This won’t be perfect, but improves on your current setup.
Not a free fix: Invest in a larger cooler to compensate for reduced cooling efficiency.
The increased temperature reading in the BIOS suggests the cooler isn't installed correctly or something similar. Avoid installing another cooler until you determine the problem. If the thermal paste covers the heatsink evenly and the cooler spreads it uniformly across the CPU, inspect for any damage. Are there any dents on the heatsink? Did you apply a protective film over the cooler's heatsink?
