I have already ordered my case(Thor V2),psu(hive 750w) and ram(G.SKILL sniper 8gb 1866). This weekend i will be ordering the i5 3570k and the ASUS P8Z77-V PRO(i will listen to any other reccomendations). My question is what cpu cooler should i get to achieve a safe 4.5ghz OC? I was looking at the tpc 812 http://www.newegg.com/Product/Product.aspx?Item=N82E16835103176&Tpk=tpc%20812 I would prefer to not get the noctua because it looks ugly but if its that much better I will. Also I would like to know if I will have any clearance issues with this ram. Thanks for all the help
