change the cooler to this https://www.newegg.com/corsair-liquid-cooling-system-icue-h150i-elite-capellix-white/p/N82E16835181216?Description=capellix&cm_re=capellix-_-35-181-216-_-Product&quicklink=true as the 5000 series runs hot and a cheap air cooler wont be able to handle 16 cores.
And you can change the case to this https://www.newegg.com/p/N82E16811112594
it may say mini but it is still a good size case that can fit a 360 rad at the bottom and top while the side can fit a 280mm rad so you have a lot of space.
