Hello, I recently assembled this PC a few months back, but I’ve noticed the CPU heats up significantly during Blender rendering, even though the GPU handles everything smoothly. The CPU usage stays low—around 5% to 40%. The graphics card works perfectly. This issue occurs regardless of the scene complexity, such as rendering the default cube. The power draw from the CPU is capped at 150W. I’ve experienced this problem since the start and also while gaming. My system specs include an RTX 3070 13th Gen Intel Core i7-13700KF, 32 GB RAM, running Windows 11 Pro. I’ve searched extensively online, so please let me know if you can assist. If you forget any details, feel free to share them! Thank you! During rendering:

It's tough to judge without checking your cooling setup. Just to clarify, what are the temperatures on the GPU?

No, I didn't build it myself. I didn't remove the protective shield covering the applied thermal paste.

You're right about the plastic sheet being removed. I'd still try to reposition the cooler and possibly reapply thermal paste to check for improvement. With good airflow and a suitable cooler, the issue might be poor contact rather than something else.
