Personally I use the Noctua D15 SE AM4. It comes with an inline resistor to bring the fan speeds down. https://noctua.at/en/products/cpu-cooler-retail/nh-d15-se-am4
If you want to stick to Cooler Master, Amazon currently has this on sale https://www.amazon.com/Cooler-Master-MasterAir-Dual-Tower-MAP-D6PN-AFNPC-R1/dp/B07CPY5LP1/ref=sr_1_1?keywords=masterair+ma620p&qid=1575995135&sr=8-1
