Sorry for the noob question, I have an MSI B250M PRO VD motherboard with 2 sticks of ddr4 crucial ballistix sport 4gb (total of 8b), and I'm aiming to buy an aftermarket CPU cooler which is a be quiet pure rock slim, will this cpu cooler interfere with my ram? or is there another better, cheaper option for a cpu cooler, sorry this is my FIRST build
