Ryzen 5900X temp flucuation OK?

Hey guys,

I have recently toned down my CPU AIO fans to make it a little quieter when doing the basics, (browsing, music, email etc..) , my "concern" is the fluctuation..it seems to range from mid 30's and PEAK, never stay, at around 58-60 degrees..

When left to truly idle (I mean leaving it for a bit without any input, it goes to high 20's / low 30's..

So basically, what im asking is the fluctuation OK on the 5900X chip?

As has been said its normal, What motherboard do you have? i added a 3 second delay to my fans ramping up in the BIOS, so the fans don't come off idle at all unless there is 3 seconds of sustained heat, it stops that ramping up and down of fans as the CPU boosts up and down in short bursts.

I currently have a MSI MPG B550 Gaming Plus.

The current profile seems pretty good, don’t hear it half as much with headphones or my speakers.

So it’s a win for me!
 
Very normal. What you should focus is keep under control under load. But your temps are good.
With the 3900x I was able to get a bit more performance but way less heat using a negative offset. I do t think the 5900x benefits as much, but any voltage lower than the stock usually is a win.
But as it is, is good. My fans only spin in a meaningful rpm when CPU hits 75C. And unless I’m benchmarking, won’t happen easily. Different CPU 7800x3D, but I believe not a much different behaviour.

Cheers. Yeah, the funny thing is that under load, gaming mainly, the temps actually stabilise and don’t fluctuate as much.

As an example I played some Death Stranding for a period to get an idea of temps under a fairly demanding game, and my gpu was peaking around 60c and my cpu around 50! :eek:

I couldn’t believe it being that low under some gaming load.

I haven’t stress tested but I don’t see the point in my system as it’s only for gaming and general stuff.

Hysteresis is the term for this behavior.
 
Yes, no problem at all, mine actually goes from about the same to higher than that 'high '70s' under load on a Noctua D15S. If you were using a 78000X3D you'ed be seeing a bigger difference than that, espeically without turning.
