WC set up for tri sli 670 and a 3820

[gumby6288]

Ok here's my dilemma, I have 3 evga ftw 670's and an i7-3820. The CPU is currently running fine on a h100 but I wasn't happy with the gpu temps on air since I'd like to OC them. I bought 3 xspc razor 680 reference design with 3 of thier sli bridge connectors. I was planning on running 3 240 rads And two pumps. I also picked up a lga 2011 waterblock since I figured while I'm at a custom build why not throw the CPU in the loop, total TDW is around 630. Basically my question is what is the best order to set this up. Do I use the sli links or just run tubing from rad to rad and pumps and blocks. I can change the loop anyway I need to, just hoping for some input here. Thank you in advance

2 240's with the gpu? And also could you idiot proof what you mean by the sli config, I've never watercooled this much and after a 6 grand build I'd like to do it right the first time lol, btw happy 4th brother

Sory meant CPU

2 240's with the whole build. I'm running a 3820 and a 690 with a single 360. Heres what you want to do.

Res > Pump > Rad > Cpu Block > Rad > GPU > GPU > GPU

3 gpus with no rad in between even though they put out more heat then the cpu? just a noobish water cooling guy but that does seem efficient.

plus i have just my 2600k at 4.6 and running a 240 rad and i get better temps when i add a passive radiator to the loop.

Water temps at any single point in the entire loop is only 2-4C difference in temps.

Passive rads should really be paired with at least low speed fans to dramatically increase their cooling potential. Whether it be an air cooler or a WC rad, anything that has to exchange heat energy from a heat bearing surface to the air does much better with active cooling over it, even if it's minimal.

the point was that the little extra cooling capacity lowered my temps.

Yea with no rad in between I know it would run, but there at 75c at load on air I was hoping for much much lower

And the gods have spoken, thank you for the help!

I played with Eva precision x for a bit, I know the temps are fine but with over clocking them I'd like to drop hem a bit. The cards have gotten a bit sketchy t high temps

Now better and final question is a koolance pmp 400 enough for this loop

MCP35x has nearly the same specs as a D5.

Also a consideration.
