I've built a 3800x and a 3600 AMD machines. Both of them have wide fluctuations in useage/temperatures from simple things like just moving the mouse. It causes the temps to bump from 40c to 60c in a fraction of a second which causes the fans to bump up and subside every few seconds. It drives me insane.

It seems the solution is to either have the fans going constantly to keep temps low, or to increase the threshold which allows the CPU to get hotter. I don't like either solution.

I'm coming from a 4690s where the CPU stays in the cool 30s unless doing very demanding tasks where it boosts into the 50s and stays there until I'm finished. It seems this is normal behavior.

I'm looking to upgrade, but I really don't want this new Ryzen like behavior with my CPU. Does Intel do this as well? Am I just stuck living with that?

Update bios and chipset drivers - seems a lot of people had these issues and it is nothing to worry about but might be fixed with newer bios and drivers...

"All right, I have posted here once saying that it is not a cooling/thermal paste issue, but a software issue, and I am here to confirm that. While I don't know what is causing the spikes yet. Switching the power plan to Power Saver (not Ryzen power saver) seems to solve the temp spike issue."

I don't notice this on my 1700 but I am on water cooling....
