Help on 800D loop route please.

Guys, can you give me your input here,

This design with the water flowing:

Pump (OUTLET) - CPU -120.3 Roof RAD - GPU1 - GPU2 - 120.2 Base RAD - RES - Pump (INLET)
Blue line is my possible fill port and green circle is the possible snap link to enable easier draining, both are not decided.

OR THIS:

with the water flowing:

Pump (OUTLET) - RES - CPU -120.3 Roof RAD - GPU1 - GPU2 - 120.2 Base RAD - Pump (INLET)

Thanks

Change the 120.3 to all intake. Ditch the fillport, I doubt you will need it. I'm going to try to mock something up in Paint right now.

EDIT: Behold my rubbish Paint diagram! This is what I'm thinking of, critique welcome.

The dual GPUs will put out a lot of heat so we want that to use the biggest rad before cooling the CPU.

thanks man,
Was sat working it out just now, the diag 2 wont work so well, i need the res to feed the inlet of the pump so it wont starve and die! so Diag one it has to be thus far.

Do you think my loop will work out of interest?

mast3r · 11 Jun 2011 at 12:32

humm, yes, that would work very well i think! Lemme see what it looks like in the case.

I swear this doesn't matter as temperatures in the loop will equalize very quickly...

The things to consider with loop order are generally flow rate and required tubing length.

Humm, never thought of that. Fair point.

This is what I will be doing in mine soon, with just slight differences to the layout, this is about a neat as I can do

Hyperst that loop doesnt look right to me

mast3r · 11 Jun 2011 at 14:53

Hyper. please explain your loop a little better for us.

Loop seems fine. Ignore the black lines. Key to parts is in OP (7 is res, bottom box is pump, then go from there).

Only concern would be that a single pump won't have enough head to push through two rads and three blocks. Go for the least restrictive rads and blocks you can find

Looks like the pump is pumping through the res to feed the gpus and even if its going the other way why have the loop going from duel rad to a triple. wouldnt it be better having the duel - gpus - triple - cpu - rez - pump then back to the duel.

Why would it matter?

As has already been discussed earlier in the thread, the order of components makes minimal difference to loop water temperature as it equalizes very soon after the pump is turned on.

As long as the rads aren't very high fpi restrictive rads (which they shouldn't be considering the size of the case) any order is fine.

sorry guys, should have explained, the pump goes to the bottom rad and then to the top rad then into cpu then gpu then res and back into pump, this way the pipe from the bottom rad could be placed out of sight and overall should look very tidy, mavity should be helping a lot, as once the water is in the top rad it has only got to go down from there.

mast3r · 11 Jun 2011 at 23:14

but if in this order the pump has no water on the inlet to keep it fed, my 655 will soon be dieing of warn baring from running dry, you need to feed the pump from the res.

hyperst · 12 Jun 2011 at 00:24

I have, Outlet of Pump > 240 Rad > 360 Rad > CPU > GPU > Res > Inlet of pump

Blue arrows are water flow

Don't understand how his diagram is unclear in this respect...the res clearly feeds into the pump

Guys, i am now making some progress!!!
The fan that sits on the underside of the PSU Bay, i am now able to fit it on the top side of the shelf thing, Question is, do it have it push or pull?
Pushing air from the top of the case into the base to allow more air to circulate the bottom rad?
OR
Have it pulling air from the bottom of the case?

The only inlet will be via the PSU in the bottom and the bottom rad will likely have 4 fans on push-rad-pull
