I have just begun a build, and hope to o/c an i7 3770k to around 4.7ghz on the Gigabyte z77x up5 I to run it. I bought a HAF-X to make sure I have great airflow and plenty of room for future expansion (eg. more HDD's, SSD's and Sli) but wanted advice on the fans / CPU cooler that will best keep it nice and chilled?
This is also to find out whether I need low-profile RAM or normal. I will be running at least one gtx 670 or 680 to start with.
Budget is not really an issue - as having something that will last a few years is more important - but obviously the less the cost the better!
I suggest getting a custom water loop if you're going to OC that high.
If you have no experience in water cooling, then high-end air coolers like the NH-D14, Silver Arrow, or Phanteks would do you good.
I generally suggest low profile RAM since the "normal" ones' tall heat spreaders don't actually have any real purpose unless you're going to OC RAM frequency as well. I wouldn't suggest that though since you'll have to adjust the voltage higher and it might damage the memory controller; not to mention, void the CPU's warranty.
