Your case and budget will determine what you can do. Noctuas stuff is all great, and the bigger the better if it’ll fit, as more heatsink means lower airflow per area is needed, or to put another way less static pressure and noise.
(EDIT) It looks like your mobo uses non-standard cooler mounting holes, so it may be slightly more complicated.
If your budget is less get basically any two 120mm tower air coolers with some kind of fan control, or if that doesn’t fit try a pair of 92mm. Honestly for the same area a cheap brand does a large portion of as well, the big difference is the range of PWM and fan tone. I use a Raijintek Themis Black on my Lan\webbrowsing rig and while its been totally fine the PWM range is only like 1100-1450rpm in real life and its a more noticeable sound (even though only similar volume) than the Noctua 140mm fan I’ve got on an H90 in my workstation.
Really though making something quiet is much harder than relocating it to somewhere it doesn’t matter as much.
