Replacing my cpu cooler that's failing , which one should i get , please help !

Hey family , recently ive been having trouble with my 120mm cooler , it feels like the pump is failing ( i idle at 60 ) and 80 degrees Celsius when browsing , i'm willing to get a new one tomorrow , ive called this shop that suggested another 120mm cooler master , for a decent price " i guess " , but ive been hesitating between that and the Arctic Freezer 36 which is pricier by about 20$

btw i have an i7 6700k and a Z170 PC MATE motherboard !
