iv recently put together a new setup having moved over from an Intel 8600k.
My system is made up of :
MSI B450 Tomahawk Motherboard (Latest bios)
M.2 Drive 970 Evo (500gb)
2x SATA Hard drives.
I have most up-to-date motherboard drivers and I am using the Ryzen 3600 balanced power plan.
The problem iv been experiencing is high temperatures during idling, the processor often fluctuates between 40c and 55c during idle. The cooler I have is an NZXT Kraken X42, which is an all in one liquid cooler with a 140mm radiator and fan setup. I often hear the fan ramping up and down even though i'm only web browsing.The ambient temperature in the room is 18c, lastly my Intel never went above 30c at idle.
I have looked at hardware unboxed review of the 3600 and he states the processor with the stock cooler idles at 30c and he lives in Australia!.
