I've noticed some problems with the temperatures on my PC. I use a 5900x cooler with Be Quiet! Pure Loop 360mm as an outtake. When I launch just one app—like Google or Epic Games—the temperature spikes to around 60°C, even though the room is only 23°C. This happens every season, but it's more noticeable in winter than summer.
The fans might be reacting to CPU temp rather than coolant temp. Not too familiar with Be Quiet products but there should be an app you can download to make it so that your fans are controlled by coolant. As for the temps, this is normal. You can check your individual core temps using something like HWINFO64 and you should see only a few cores heat up that much. You could run a stress test like Cinebench or any sustained load to check if your cooling is working properly.
