I have a Ryzen 3700X which is a very similar chip and I use the stock Wraith Prism cooler.
Idle temperatures are between 41c - 54c as it often spikes up.
During intensive gaming such as Battlefield V and Red Dead Redemption 2 it runs between 65c - 72c.
This is at 4K resolution with an RTX 2080ti GPU and 3200 MHZ RAM in an Asus B450 Plus Gaming motherboard.
