So I have my i7 5930K and I'm installing the rad for my cpu cooler. What's the best way to do the push pull? Do the top fans intake or exhaust? TIA.

For myself.. Ive always done cold air intake. The radiator gets dirty tho and will require more cleaning. When Ive had them exhaust... i get less dust by higher temps. It's up to you really which youd prefer. I have a CM Cosmos II case and the ONLY THINGS i ever clean is the radiator and the screens that came with the case. Otherwise all my components and internal fans stay clean. Id rather have to clean a little bit and have lower temps than not really have to clean but have higher temps (and thus faster spinning fans).

I was thinking the same. Keep a positive pressure in your case so it doesn't get as dusty. I have the Corsair 750D with 2 140MM Intakes, 2 140mm Exhausts and will have the H100i (2x120mm) Intake. Should get me a good positive pressure.

Best to have a little space between the fan blades and rad, such as by using a shroud or fans with built-in shroud. The thicker rad fans are more difficult to find now, so best bet is probably a buying a cheap shroud or making one. For easily cleaning the radiator, just take the fans off of it, and then gently spray alcohol the opposite direction that air passed through. The alky takes off any dust and the residues that cause the dust to stick (nicotine, oil, etc.).

I am going to assume you're speaking about a AIO cooler and not a custom loop. I would recommend, depending on the case, to either have the top as intake if its filtered or have it exhaust if its not.

I find it silly intake on top as graphic card push air toward the top and the hot hair itself go toward the top  intake through radiator from front... air enter go toward the gpu that pick the air from under the card and push it up and a final fan to help easing the way out toward the top. in this way there is not contrast in the direction of the air flux and is a simple curve from front to up with not deviation or contrasting direction 2 fan in 1 fan out to keep the positive pressure

Actually, that's a blower style fan. You're thinking of ACX Coolers which this isn't. Either configuration for that Swiftech Rad is fine. I would have personally chose to put the rad up top. Regardless, top or front is fine. As long as there's positive pressure created and sending out the exhausts out the back and top if not used as an intake.

I see what you mean about the GPU but honestly make no real different hot air is suppose to go up and if you put it on top you push it down and then you supposly blow it out the front? the back? the back fan would be too close to the top fan create weird turbolence... good point about my GPU you are right is a blower it doesn't really factor in... but most of GPU are not like that i was talking in general i guess I think mounting it like in the picture is the most "natural air flux" if you put it on the top i would get put it all 3 fan on top as "in" and no fan "out" let the air go out wherever it feels like

good point about my GPU you are right is a blower it doesn't really factor in... but most of GPU are not like that i was talking in general i guess
I think mounting it like in the picture is the most "natural air flux"
if you put it on the top i would get put it all 3 fan on top as "in" and no fan "out" let the air go out wherever it feels like
Hot air surely rises especially if there's no internal case pressure but you can create your own pressure and force the air in your case once closed up to the back or where ever you choose too. Reason why I say up top is because the air bubbles in the loop will stay inside the radiator while having it side ways can possibly invite air bubbles to the mix since the reservoir/pump sits up top. Not disagreeing with the positioning but that's how I would see it as. The same argument can be said that air bubbles void the space where the water should be when cooling if it were to be set up top. heh Don't get me wrong, I like Swiftech product as I have 3 CPU WBs from them, a GPU WB, a few reservoirs and two pumps from them but I am not a fan of the reservoir/pump/rad all in one design. For bleeding reasons mainly and the bulkiness of it all. But I still do recommend them to folks who just want to get their feet wet at a budget pricing though.

I have a 5930K and I am cooling it with a NZXT Kraken X 61. I have 4, Noctura Industrial 140 mm fans in a push/pull config on it and I have the fans blowing out the top of the case. I have had no problems keeping my CPU cool. I have a harder time keeping my GPU's cool so I opted not to bring hot air into the case by having my Kraken set up with the fans intaking air. Hot air rises as well which helps exhaust it out the top through the cooler. These fans are DEATHLY quiet. I have all my fans set up on a fan curve using the motherboard's option to do so. I NEVER hear them really spin up to Maximum. My temps are about in the lower 50's when I play BF4 at 2560X 1440 @ 118 Mhz with all of the eye candy cranked up.

You can also knock a few degrees if you switched the top to intake. ;) I've experienced it. I only do top as intake if its filtered which it is, otherwise I use it as a exhaust. Again, you can control your warm exhaust air in the case with positive case pressure. The hot air rising isn't going to argue with the stronger air flow coming through that will redirect it is my point.

of course it wont but why fight a natural force when u can use it that's my point plus u are blowing directly to the GPU that will block the flux from the front you hit the GPU and divide the flux up and down making and overall better circulation but i doubt it matter honestly at the end do as you prefer those are nitpick that will really don't effect much at all

Prefer to run pull only if one set of fans is used. With push only, some fans will spill the back pressure over the sides getting worse temps. If pull only, and spaced a little away, a pocket of negative is created so the whole rad get a nice and even stream of air. Prefer to clean the radiator before the fans. I just finished cleaning my rad fans after five years of ownership, and smoked quite a bit during the first four years I owned them (quit over a year ago). It was a pita cleaning the fans of dust and nicotine, but they look new again and still run perfect

OP, if you want the coolest temps possible, have the top rad as intake and the rear as exhaust while having the front as intake as well. Done deal. If not, its not the end of the world and the difference isn't that huge anyways so either way is fine.

So I have my i7 5930K and I'm installing the rad for my cpu cooler. What's the best way to do the push pull? Do the top fans intake or exhaust? TIA.
Personally, it depends on the environment it is is. Normally, I say draw it in form the front (and possibly side) and out the top (and possibly back), this makes sense as hot air naturally rises and you are not likely to gain much out of forcing it the other way without a good reason. However, my system sits by a window AC unit, so I have the top as intake and exit the front, as it is sucking air in from the AC. If your system is say under your desk and there isn't a lot of space between your case and the desk, I say use the top as intake, otherwise you are likely to make a very warm pocket of air under the desk which may impact cooling. Neither option is "correct" all the time, it really depends on what its around. Someone also mentioned having a gap between the rad and the fan, that is definitely true, however i do not see the huge volume of shroud options I used to see, making your own is likely for the best, granted in the end, the change in delta wouldn't be more than a couple degrees, which can be helpful, but is certainly NOT a make or break difference.
