Eh yah but it's also matter of taste right? I mean I agree that's how I am. But like the build he linked, wayyyy over kill but still looks good.
With out overkill we wouldn't have jet engine powered school buses drag racing either 😁

First things first - no no no I don't to go overkill for the sake of it smile.gif I just want my system reasonably cooled AND quiet and that;s it. Build I've linked is pure overkill mod made only for a show, but the idea is there (in sense where to put those additional rads -> just connect second case!) That's why I'm asking You guys for some advice. I know 1 P3 (I like the smaller one) won't fit radiators I need to sufficiently AND quietly cool my system.

Let's say oced Titan XP is 300W TDP x 2 = 600w. Oced 6850k about 200W. That's about 800W of heat to dissipate. If I go with the so called rule of thumb I'd need 720 or 840 rad space. BUT I want to run in on low rpms so things are getting complicated...

Aren't those fairly restrictive rads? Wouldn't want them in multi rad setups I assume?

If you're planning to get 3, they might be a little too restrictive, the Hardware Labs SR2 might be more suitable.

EDIT: I stand corrected. It is approximately as restrictive as a moderately restrictive CPU block. As @Gilles3000 pointed out, the SR-2 would be a better choice if you are using 3 or more.

They are not restrictive when compared to say, a GPU block. I would have to dig around for the numbers to see how many 360GTS would equal the restriction of just one of your CPU or GPU blocks. The whole thing about Nemesis rads being restrictive is a bit like saying "X contains more moisture than talcum powder" and suddenly people think that X must be the Pacific Ocean.

Its just unnecessary extra restriction though, the SR2 actually performs better both low and high fan speed, and is much less restrictive.

Agreed - see the edit to the post, you are correct.

But....the SR2 is also 60mm, so not ideal for every application. Obviously, in this case that is not an issue.

So, to get it clear: 3 x 360 rads (eg. SR-2 MP OR XSPC RX360 V3?) + 1 D5 pump will be enough to cool 2 x TITAN XP's + i7-6850k (only cpu block, oced, but nothing extreme) and stay quiet with 600-800 rpm fans?

This would be great news to me, a LOT less money to throw around & parts to mess with thumb.gif

Buy a Mora 3 Pro or Phobya 1080(3 X 360) with 180/200mm fans support.,put it in the back of the P5..

A 480mm Rad in front (Alphacool XT45,Coolgate CG,XSPC RX)with low fan's.

It'll be expensive (not an issue i guess),with outstanding perfs and silence..thumb.gif

Absolutely enough radiator. I'm sure you will hear mixed feelings on the single D5, and whether you would have to run it at a speed that would be too audible or if a second D5 would benefit you in that regard. I have done two blocks/three rads with a single D5 in several configurations with no issue, typically with the pump at ~2100rpm on low temps with a ramp up to 3500rpm at higher liquid temps. Never had issues with flow, but that will vary with different blocks, rads, angled fittings, etc.
