Replaced the CPU, but temperatures are fluctuating and fan speed isn't stable.

Hello, Your Ryzen 5 3600 with its original cooler seems to be behaving oddly now. After replacing the CPU, you experienced BSODs earlier, which turned out to be a faulty chip. The shop replaced it, and everything worked fine until recently. Today, while downloading a game from Epic Store, you noticed unusual spikes in both CPU temperatures and fan speeds. The temps jump from 60 to 70°C, then drop back to 60 and quickly rise again to 70°C. The fan speed changes in sync with these temperature spikes. It seems normal for this pattern, but it’s strange since it didn’t happen before the CPU change. Have you tried checking the cooler connection or airflow?

Usually things run smoothly, but higher CPU usage makes it warmer and boosts cooling. You adjusted the fan settings in BIOS for your cooler. What temperatures do you see when things are under load?

It tends to run hot at around 70-80°C. I haven't adjusted any settings in the BIOS, but it's possible they made changes. I'm planning to restore everything to the original configuration, which might affect the fan curve.

Modify your fan curve for a gentler response. The readings you observe are mainly from a few cores, yet the fans seem to treat the whole CPU as if it were much hotter than it really is.

Overall everything works fine, though the CPU is running heavier which makes it warm up and the fans speed up. As I mentioned, you can adjust a custom fan curve in the BIOS.

Now that all systems are secured, I notice these spikes still occur during idle. They happen less often but cause the CPU to jump from 45°C to 60°C and back even when nothing is running.

The claimed idle condition is misleading since several background tasks are active, needing one or two cores to function. This explains the temperature increases.
