Thing about an internet browser is that it is surprisingly CPU intense, which is why it slaughters battery life. If you look at Task Manager when you open a new tab to pretty much any given page, such as a news site or search engine site, especially if it has images, it will put a several percentage load on your CPU. As AMD Ryzen 3000 series CPUs can clock down very low and drop their voltages very low, and due to the Turbo algorithms which will spike the temperature up in a couple of seconds and then slowly drop back down.
Unless you are seeing sustained voltages of 1.45v-1.5v under idle conditions in Ryzen Master, there is nothing to worry about.
These temperatures scared me, after looking at other forums and threads and seeing that 50-60 degrees celsius (or even 70 degrees) is normal, but only when loading heavy applications and games.
Also, my older cpu ryzen 3 2200 never went over 33-37 degrees while doing the same tasks and now with this cpu the temperatures are 20+ degrees higher.
I haven't overcloked anything as of now. Any other tips to monitor and check things?
Some screenshots:
Just make sure your BIOS is up to date and you're getting your measurements from Ryzen Master. Just wanted to add by 3700X for comparison. Even on a much more powerful cooler, the Corsair H115i, idle temps range from 35-50*C depending upon ambient temperature, simply because Ryzen 3000 series CPUs can switch power states in a millisecond, and every little background task will spike one core faster than it can be displayed.
Hm, seems like it kind of defeats the purpose of buying the aftermarket cooler for the cpu or at least buying something for a relatively cheaper price. Or just keep the stock one.
Yes, everything is up to date, including the BIOS.
Still trying to learn new things, so I can properly manage my computer. Though I am not someone who is good with these stuff 
Thank you for your help black_zion. It is greatly appreciated.
That's not true. Aftermarket coolers allow for higher clocks and quieter operation. Can't do all core 4300mhz clocks on a stock.
Just adding a Ryzen Master screenshot - seems like temps from Ryzen Master are very different from the temperatures that Core Temp shows - Core Temp shows between 43-63 C and they stay mostly around 55-58C.
In any ways, I am currently having an issue with the core voltage - you can refer to the Ryzen Master screenshot below or my CPU-Z screenshots above. My core voltages generally fluctuate beteen 0.23 Volts to 0.9 Volts and rarely hit 1.0-1.1 Volts. AMD Support said that this low voltage is not normal and that I should set the voltage to AUTO in BIOS.
I am not running any heavy programs though (just the browser) and I haven't checked the voltage during game play etc - I am not sure if that generally matters for voltage.
The peak core voltage does appear low but it's a dynamic number depending on load and is probably something the motherboard manufactures have set for low load values.
Your average core voltage seems about right for 3 cores sleeping.
Could we see a screen shot of the voltages under load.
Here's mine to compare.
and when I am running cinebench R20
You don't have your XMP profile for the memory enabled in bios btw.
Hello!
Yes, I know I haven't set up XMP. I decided to leave it for last and deal with the temperature and the voltage of the cpu.
So, I guess what AMD support told me about the voltage not being normal and that I should set it to auto in BIOS is not correct?
Could you please link me to an article where I can read more about dyamic core voltage?
Here is a screenshot, when using CinebenchR20 (about 15 degrees higher than yours; I see you have 3600x, but still):
And a screenshot of the Cinebench results:
