CPU temperature spiking at idle

My ryzen 5 1500x started spiking in temps while idle since I overclocked it to 3.9ghz@ 1.375v. It jumps from 33ºC to 43ºC in less than a second, before slowly dropping back down to 33ºC. I put all fan speeds at 100% to keep cooling constant as well.

What are you using to monitor the temps

That sounds normal to me.

What are you temps during stress testing?

 

As long as you are under 75°C on Ryzen, I wouldn't worry about it at all.

They are around 70-75ºC on prime95 after an hour

Normal, set the fan curve so they wont react to the spiking.

I have all fans on 100%, wouldn't that eliminate that possibility?

Well if the fans are at 100 even at idle, which makes no sense, you cant stop the temps from spiking. Don't really see the issue.

Do you have Ryzen Master open? Have you tried opening msconfig (Start Menu - Run) and temporarily disabling everything in startup along with unnecessary non-microsoft services? At 'true' idle, your cpu should sit in the lower 30s.
