pumps for 3x gpu loop :)

[NKrader]

2x ekvga waterblock
1x 9800gx2 ek block

I think this would need like 2x ddc high flow top with dangerden 18watt new ones.

Also what would be smallest tubing you would run on this? As its super restricted and relys on pressure not flow could go pretty small huh? I'm using primoflex tubing only and bp compressions.

Rad will be 240mm tfc

Cheers,

One ddc 3.25 will suffice. Don't underestimate it's monstrous head pressure.

Alternatively if you are dead set on using dual pumps, you could get dual mcp 350, mounted on a ek dual top, should do the trick. But one 3.25 will do it.

Heh last time I asked if I could run 1x ekvga with 1x heatkiller I was told I couldn't..

Ekvga is one of the most restrictive cga blocks out there its like running a HK..?

So running 2 of em plus another block..? Really 1 pump?

waterlogged so these 3 blocks on 1 ddc would work?? really?

really? so i could have ran them inline with my HK3.0.. gayed..

also what size tubing could be a good smaller size?
aaaannd would those blocks fit with full cover heatsinks from swiffy?

:shocked:Ouch! Universal GPU Supremes? Really?? If your using 2 of those, your better off doubling up on 3.25's. . .alone! Yes, they're that restrictive.

yea thats why i thought u guys were crazy when you said i could do it with 1ddc lol... :up:

think i run them in paralell with 2x ddc (http://www.performance-pcs.com/catalog/index.php?main_page=product_info&products_id=25841) with ek powertop then merge and go to the 9800gx2 :shrug:

Res->Pumps->Y->EKBlocks->Y->9800Gx2->Radiator->Res

or should i go 2x D5 in 5.25bay?

i love those blocks :D

so.. tubing size? and swiftech Universal sinks?

[NKrader]

pumbski

[Waterlogged]

Sorry NK, slipped me mind.

D5 won't be strong enough to get really good flow through those EK Uni-GPU's.

3/8" x 5/8" should work nicely

Going parallel on the EK Uni-GPU's should relieve some of the restriction they have, just make sure the tubing runs are identical in length.

kk im gona run em paralell have idea as to running tubing :D and for pumps..

how bout this? with 18watt ddc?

how much heat would that dump into the loop?

[gosmeyer]

Is that not series :shrug:

18W DDC's dump ~16W of heat into the water each so 16x3=48W.

As for the top, way overkill.

It seems a lot of the newer ppl to Liquid Cooling are vastly under rating the power of the pumps we deal with.

He was referring to the EK uni GPU blocks.

Double top would do it? I'm gona speed control everything aswell

Why speed control? Just go b*lls out. http://img2.imageshack.us/img2/6132/nutkick.gif

Seeing your going to parallel the bad restriction in the loop it won't be anywhere near as bad as if you had gone serial on them so, yeah double top should be enough.

[NKrader]

controller becuase i will have to get bigng and mini ng anyways.. 8x 120mm fan 2x 140mm fan 3x 80mm fan :)

plus im planning for end product as i dont like to buy things twice..
