Ive got a new case coming, so redoing my loop, and throwing my two Black Ice GTX Gen 2's (360) in the loop to take the place of the RX360 there now. Looking for thoughts on if it is worth it to keep the Maximus V Formula's motherboard block in the loop, or would it make a difference on the final overclock?

Also, thoughts on keeping push / pull on the radiators, or just run 3x AP-15s on each? Final loop will have a 3770k (at max OC i can get stable), 2x GTX680s (reference), and potentially the motherboard (With either the "stock" water cooling, or a MIPS block if there is one available down the line and if needed)

Thoughts are appreciated guys, thanks.

Hey there old friend;)! The description is a tad unclear, so I want to make sure I get this right..you are going to be removing (completely?) the RX360 that is currently the main radiator in the current loop, and you are going to replace it with a pair of BI GTX (240s, 360s?)..

If you are replacing the RX with dual 240s, I would recommend against that, even if they are high FPI models..My reasoning behind this is my first loop had a high FPI Koolance 360mm rad and a semi high FPI XSPC thick 120mm rad which was replaced with my current 360 rad (60mm thick, 8 FPI, exact same test results as your RX)..The single 360mm actually performed about 5% better, despite the 1/4 drop in surface area. I wouldn't chalk it up to restriction, as the loop was/is being driven by a MCP655 on its full speed (so fast its impossible to bleed unless i set it down to 2nd lowest speed)..

I'll tackle the push/pull topic before the MB WC issue, since it has an impact..I would stay with single AP-15s unless the radiators are insanely high (20FPI+) and you want to run the fans lower then their default 1850rpm...

As we all know, cooling the VRM area of a MB is super important when WC, since they no longer get airflow from the HSF..For this reason I mount my fans on the bottom of the 360mm rad (literally right on top of the VRM 'sinks) and them pulling air in..Even with my AP-15s @ 5V, this results in way more air flowing around the VRMs, and a positive pressure setup to keep dust way down.

Now based on the information above and the orientation you choose, you can decide if you want to keep the VRMs in the loop. Since Asus was kind enough to charge you for the feature:D you might as well make use of it right? The only concern I would have is if they cheapened out and used Aluminum in the MB block, which we know is a no no to mix with our mainly copper/brass/nickel loops of current..If that is the case, I would forgo it unless you pick up the copper MIPS block.
 
Its a copper block, MIPS block is potentially in the future, as for fans, I currently have Push/Pull with 6 fans on the RX360. yes it is being removed from the loop completely to go and cool 2x X5680s, I clarified the initial post , i have 2x Black Ice GTX Gen 2 360 radiators, doubling the available rad space, with what in some cases is a superior rad. Just trying to figure if its worth picking up a few more fans to keep push/pull on the entire setup (going into a case internally so adding more later will be a PITA.
 
You can try mounting some fans on the outside of the case to work with the push/pull configuration. I generally always recommend going with push/pull and using a rheobus fan controller. That way if you are worried about noise or operating your system at a lower clock speed, you can always turn the fans down a bit. But with 2 radiators, just having the 3 fans on each will probably work out okay, especially if you are having space issues.

As the other poster mentioned, it is pretty important to make sure you still have airflow going over the motherboard, I usually put my radiators in the front of my case and had the push/pull flowing into the case over the motherboard, with some exhaust fans on the rear and top of the case pulling the air out. Even though you may be getting warm air off of the radiators, it still helps cool the components on the motherboard and unless you are running some extreme heat, its highly beneficial. Consequently that is also why I go with push/pull to get as much cool air as I can flowing through the case.
 
airflow wont be an issue, going into a 900D, rad on top and rad in bottom area, same with fitting push/pull that is a non-issue, the question is more is it cost effective, or am i going to see a delta of ~3 or 4 c ..... in which case it would be pointless to buy more fans.
 
Still looking for some insight, looking to move everything from the Antec 1200 to the 900D this weekend or next hopefully.
