CPU Temperature and Clock Speed

[Mohammed AlManzalawy]

Hi, 

I've just built a new PC with the following specs: 
AMD Ryzen 9 5900X
Nvidia GTX 1070
NZXT X52 240mm AIO
32GB RAM

When I am at idle state, I see the CPU fluctuating between temperatures from 43 to 60 dC
also I've noticed the CPU clock goes all the way upto 4940 MHz and stays at it for some time although the manufacturer data says it's boost clock is only 4.8 GHz. 
Is this normal or not?
Thanks

going up to 60C At "idle" is decidedly high.

 

But a CPU Core going as high as 4900 or so?  Not weird.  That's how single core boost can work now.

I feel like you aren't completely at idle. Is there something using the CPU when you think you're at idle?

They can boost past 4.8 GHz as long as they aren't too hot and have enough power to do so.

Only a couple of monitoring software 

I also don't understand why the processor boosts to a higher frequency than the factory default max boost frequency although I didn't do any overclocking.

If PBO is enabled in BIOS, that is to be expected.
