I am an auto mechanic going on 30 years now and pushing air directly over the air conditioning condenser mounted on the front of the radiator provides the more instantaneous cooling effect you need for the high pressure side which makes the a/c function the way it does on a car and facilitates the gas form of the freon returning back into a liquid state to be compressed again. You take away that front mounted condenser push fan and the pull fan used for the engine cooling (antifreeze) radiator is not enough to give your ac the desired 43F at the vents inside the vehicle.
On the other hand... two front mounted push fans on a vehicle is enough to cool both your condenser and radiator if the pull fan on the backside fails... there are many vehicles now setup to do exactly that, to run the condenser fans mounted on the front continuously if the radiator coolant "pull" fan fails.
The hoses on the H100i do not seem removable and I see the rounded rectangle hole you are referring to but there is no way to pass the cpu cooler/pump thru it. Mounting the rad on the front seems like a cool idea but my main concern was with this particular rad sitting on it's side... there is no real pressure inside these system to have to worry about leaks from the rad and the hose crimps seem well enough.
I am going to mount the rad inside and the fans on the front like I set it up last night but disassembled till I got more information... you wouldn't know if these fans are optimized for pull do ya? maybe I should just order some which state as optimized for "push" that way I can be certain... I honestly can't see how it matters though as the blade pitch on the corsair fans are exactly the same as the cooler master ones which came with the case. I would think that kind of push or pull labeling on a case fan would be a bunch of hoopla unless there was a drastic or radical pitch difference to the blades themselves... which in turn would make the fan case thicker to accommodate the steeper blade pitch.
PS; I was looking at the IV Extreme too.. but I figured I didn't need all those PCIe slots because when Ivy-E is available so will be PCIe 3.0 which can only run 2 cards at X16 PCIe 3.0 speeds. All other peripherals are pretty much usb or eSata or firewire now anyway. I only need two x16 capable slots at PCIe 3.0 Rev. that's why I got the RIVGene... saved a few bucks and those extra slots even on the Gene are just going to be sitting there unused.
Push/Pull being better isn't a theory. It's a fact proven time and time again from actual scientific testing. PC's and Car's running Freon are NOT the same thing. And with any radiator in Push/Pull you definitely want all your fans to be static pressure optimized. There isn't 1 static pressure side. You would have 2 high SP fans on one side and 2 high SP fans on the other side. It's not a HUGE benefit but you'll get about 20% better cooling in Push/Pull than you will in one or the other. Check out martinsliquidlab.org if you wanna see some testing backing it up.
I don't think that any fans are actually optimized for push or pull. Just i guess some perform like 1% better in one or the other. Fans are optimized for Static Pressure (rad or cooler fans) or CFM (chassis fans). Generally any stock fans that come with anything aren't the best you can get. Corsair does make some great high SP fans, the SP120's would work great for your radiator. Best results would be to buy 4 of them for your 240 radiator. Scythe Gentle Typhoons are well known to be the best. Also Noctua NF-F12's are good, Noiseblocker NB E-Loop's, and there's plenty of others too. Just pay attention to the mmH20 rating for a better idea. Martinsliquidlab.org has some really extensive fan testing if you need help choosing good rad fans.
As far as the oval holes, i wasn't bearing in mind that you have a Closed Loop Cooler, so yeah that wouldn't work for you. You definitely should mount it inside. You'd have to cut more than a hole to make that work.

even though the other sockets already have PCI3 3.0 they only have a maximum of 16 lanes.
I wouldn't go with anything other than a LGA 2011 simply because of that fact and the iGPU's make no sense to me on a machine which is made for gaming/editing/HD viewing and has a Graphics card... *** was intel thinking? trying to crush or take over the after market graphics industry lol? what a wast of die space!
The extra 40 lanes on big motherboards come from the PLX bridge they put on them (like the Rampage IV Extreme). So 40 lanes from the CPU and 40 lanes from the PLX bridge. Any board that you see with x16/x16/x16/x16 or x16/x16/x8/x8 or even x8/x8/x8/x8 has either 1 or 2 PLX bridges installed. That goes for Haswell, IB-E, IB, SB, SB-E, and anything else. That's one of the reasons that boards with heavy GPU support are so expensive. So the Rampage IV Extreme is still gonna give you (x16, x16, x16, x16, x8) in PCIE 3.0 on an IB-E chip.
iGPU's aren't really to replace dGPU's. They've always been there. Most general PC user's don't have any use for buying a graphics card. SB-E and IB-E and such don't have iGPU's because they're enthusiast chips with enthusiast chipsets. So people that are willing to spend the extra money on an Express CPU/Chipset are generally gonna be wanting a nice GPU to go with it.
When you see a board with more than 40 PCI lanes, you'll see (usually or always) under the CPU socket (between the CPU socket and the PCIE slots) a long metal thing that looks kinda like a Lincoln Log with a metal pipe going to the VRM's and a metal pipe going to the chipset. That's the PLX bridge. You'll see it on most motherboards in the $400 range. Then look at a board in the $200 range and you won't see one. That $200 board with no PLX bridge only has 40 PCI lanes.Edited by kpoeticg - 8/1/13 at 7:27pm
