thought on wc design

[robertchalmers1]

i have made a rough diagram on how i thinks best to install this loop when my stuff arrives tomorro. does it look ok or does anyone have any suggestions on best way to install loop

 

[Gilval]

Loops order shouldn't make any significant difference as the fluid flows rapidly round, although res before pump is always good

I tend to just go for what looks tidiest

 

[robertchalmers1]

yeah thats what i thought trying to get this to be as neat and tidy as possible, i just hope i have enough rads tho

 

[Gilval]

Without doing the calculations I would have thought that should be plenty, certainly for running at stock clock speeds.

 

[robertchalmers1]

i was gonny oc the fx8350 once its complete along with the cards

 

[Gilval]

OK you should probably try and calculate the expected heat output and compare that to the heat dissipation that you should get from the setup you're considering. I had a very quick google and there is this page that runs through some fairly in depth calculations:

http://daemonkin.hubpages.com/hub/Choosing-a-radiator-for-pc-watercooling

Someone else on here might have some better links though

 

[robertchalmers1]

that page doesnt make any sense to me

 

[Gilval]

OK as a rough guide I used this page for info on how to calculate the power usage of your GPU's and CPU:

http://forums.pureoverclock.com/cooling/2495-basic-water-cooling-guide-beginners.html

About a third of the way down the page is the radiators section and this goes into a basic power calculation for your kit to get an approximate heat calculation. You will need to have an idea about how far you're going to overclock your CPU first though.

Does that one make a bit more sense? There is also this page that goes into more detail like the first one I linked, to do with temperature calculations:

[Gilval]

Putting your CPU and both GPU's, the max heat output of stock clocks comes out at about 520W, but that's at 90% utilisation so worst case scenario.

Hopefully someone more experienced in overclocking can help you from that point of view as that's not something I've got particularly involved in I'm afraid. Research is key though

Hope that helps a bit

 

[robertchalmers1]

thnx fo that so i take it if it uses 520w i can calculate how much rad space i will need

 

[Uncle Petey]

I'll save you the trouble and say that 360+240 is absolutely fine for that setup

 

[Gilval]

Going by that figure then yeah, a triple and a double should be ample. Which rad's and fans have you ordered?

 

[Uncle Petey]

Also, what reservoir are you using? Top fill can cause issues.

 

[robertchalmers1]

im using the following pump/res

1 x EK DCP 4.0 Pump (12v)
1 x EK-RES X3 150 Reservoir

the rads are the 360 ek pe and 240 pe

 

[Uncle Petey]

Those rads will do a grand job

To use top fill with that res, you'll need this http://www.ekwb.com/shop/reservoirs-and-acc/reservoir-acc/ek-res-x3-top-v2-multiport.html and this http://www.ekwb.com/shop/reservoirs-and-acc/reservoir-acc/ek-res-x3-internal-tube-12-16-40mm.html.
At least I think that's the right length internal tube.

i take it by that you mean to run a second hose to the top of the case with a fill port attached to it.

also the 2nd item whats that used for?? i take it these res cant be filled the same way as the all in one pump/res drive bay combos are

 

[Uncle Petey]

It's so you can use a second hose as a fillport AND so that you can have the loop feeding into the res from the top (as in your diagram) without causing issues.

 

[robertchalmers1]

ok. i will need to order those parts. i was going to have the res the other way round with the single exit at the bottom straight into the pump with the end with multiple inlets at the top i assumed that would work ok
