M4A89GTD PRO/USB3

Will I be able to use HX318C10F/8 memory module with my ASUS M4A89GTD/PRO USB3 mboard? This is the RAM https://www.amazon.in/HyperX-1866MHz-Desktop-Memory-HX318C10F/dp/B00J8E91UO/ref=sr_1_3?crid=1PA4RHPQALHSL&keywords=8gb+ddr3+1600mhz+desktop+ram&qid=1580544803&sprefix=8gb+ddr3,aps,321&sr=8-3...

I currently have a stock cooler on my Xeon E5-2670. If I'm going to replace the cooler, will I have to access the other side of the motherboard or could I use the same mount that I already have and just replace the brackets without having to get to the backside of my motherboard. The reason why...

Looking at the following case http://m.newegg.com/Product/index?itemnumber=N82E16811146102 the cpu clearance is 160mm. Would like to get the CM Evo cpu cooler which is 159mm. Is 1mm not enough space? Seems like several cases have 160mm clearance.
