best? - usually its more a budget question ;)
best would be:
1. Thermalright SilverArrow-Extreme AM4
2. Noctua NH-D15
but both are around 100$ - and actually you wont need that
what you are looking for is:
Thermalright Macho120 AM4 (50$)
or
DeepCool Neptwin RGB (40$)
cheapest good cooler is "LC-CC-120" (22$; RGB or ARGB for 26$)
