Keeping 4670K cool at 4.5 Ghz

Is a Cooler Master Hyper 212 EVO enough to keep a 4670K cool at 4.5 Ghz or do I need a larger cooler? I'd rather stay away from liquid cooling just because I don't want to risk it leaking an frying my components.

Haswell runs extremely hot, and 4.5, while easy to hit on sandy or ivy bridge, is going to be pushing it. You're going to need a beefier cooler than a 212 evo.

Yeah my 4770K got too hot past 4.4 GHz on air too. But my liquid cooler gets here tomorrow!

From what I read, about 70% of Haswells can hit 4.5 so hopefully I'm lucky. If the cooler master isn't enough, which cooler would you suggest? Would a Noctua CPU Cooler NH-U12S work?

Those are Haswell I7s, though, and it's been proven that Haswell gets binned pretty significantly. The U12S isn't worth the money, to me. Is there a reason (such as size) that you're avoiding the larger coolers like the -D14?

I just want to make sure that it can clear my RAM. I'm getting the Corsair Vengeance Blue 8 GB and it has a heat sink on it so I don't want a cooler that sticks out too much.

...then I suggest you get different ram instead of a lesser heatsink, as all good heatsinks are going to stick over the ram.
You know that heatsinks on ram do absolutely nothing of value and are just there for show, right?

Also, just throwing out there, you might not want to do custom watercooling, which is perfectly valid. (I just about had a heart attack when I noticed my loop was slowly unscrewing a barb and dripping ever so slowly onto my motherboard.)

That being said, closed-loop liquid cooling like the h100i has gotten to the point where the technology is reliable enough that I would recommend it; and I was an AVID fighter against the early all in one solutions. The newer bits of kit require no maintenance, very very rarely fail, and do a good job cooling in situations where size is an issue.

I know the heatsink on RAM doesn't do too much but it matches my build overall so I like it more for the looks. I looked up the D14 though and it looks like it has a lot of clearance so I think I'm going to get that one with another 120 mm fan so that I can have all three spots filled for optimal cooling. Their website shows it's compatible with LGA 1150 so that's ok. Now to see how high I can get the 4670K. I'm not looking for a record here, just high enough so that it won't bottleneck the two 770 Classifieds at 5760x1080.

Bear in mind that any cooler compatible with LGA 1155 is compatible with 1150 - the mounting holes and cooler specs are exactly the same.

Also, don't bother with the extra fan; it's not going to help move air any faster or really give you any better performance. The only thing it would do is help shove air through a high resistance area, which is why you see double fan setups on watercooling radiators. For something like the -D14, all it'll do is be a waste of money.

That being said, you aren't going to have to get it that high. Even 4.2GHz should be more than plenty to feed those graphics cards.
