The H70 seems like a good bet as I think bigger air coolers will be a tight fit between the high ram heat spreaders and the big nb heatsink on my mobo. My question is what kind of temp improvement should I expect with this cooler over stock? My temps are good now but could be better and I'm not really looking to go crazy with OCing but I have this kind of obsession with getting temps as low as possible.
I don't know about the H70 but I do have the H50 and used it on my 980X for a couple of weeks while I gathered the pieces I needed for a custom loop.
I had two Panaflo 38mm fans push-pull on the H50 and my temps (folding 24/7 - 100% load) at 4.2GHz@1.3v hit a max of 72 degrees at an ambient of around 15 degrees. I ran caseless and had the window open (in winter) during this time.
Since moving to a custom loop, i.e. the XSPC Rasa 240 (it was the only kit that would fit without modding in my V351), temps have dropped between 10 to 12 degrees; same setup (folding 24/7@100% load), and I've bumped up my OC to 4.4GHz@1.35v as well.
So...to answer your question, I suspect the H70 ought to do better than the H50 but as others have said, going with a custom setup is perhaps the most cost-effective. Plus you get to satisfy your obsession with keeping temps low too!
