I have a Noctua NH-C14S and a cooler master v8(one of the older ones that has 6 heat pipes). I just got myself an x58 sabertooth motherboard and an x5675(6c 12t) which I plan to overclock hopefully to around 4.5ghz depending on silicon lottery. I'm putting it in an nzxt Phanteks Eclipse case with two front fans and one fan in the back, and I use a msi gtx 1060 6gb gaming x gpu. Which one will have the best raw cooling performance and would the fact that the Noctua blows air downwards help with the northbridge temps any? I already have both air coolers so I was wondering which one you guys think I should use and why.
