another "Will this work" thread

[RedPhoenix]

first of all is the Pump too much for this setup? I dont think so.
Eheim 1260/1060, 600 gph

It will be in this setup




Maze 4-1 226 watt pelt CPU
Maze 4-1 80 watt pelt GPU
1972 Chevy Impala Heatercore
Res with 2 inlets 1/2 and a 1" outlet to fit the pump

Since it will be split, this pump should work way better than a Eheim 1250, right? Or will it just be a total waste.

[RedPhoenix]

bump.

[ralf_c]

looks fine to me.

have you thought of using the mcp600 or an iwaki

[pHaestus]

Most users of the 1060 have been less than impressed. It doesn't produce that much more head than the 1250. I like the Swiftech MCP600 a lot and that's the pump I'd recommend.

[RedPhoenix]

Well i am kinda limited to where i can buy it because this is for christmas and i dont think my parents will be thrilled about going to different online stores and buying everything. so far all im getting it from is dangerden.com I dont know if i should go for the 1060 or the 1250 for my setup. Not to concered about the heat becasue im already going pelt so it will be below zero. I just want to cool the blocks the most effective was possible. What should I do?

[pHaestus]

Get everything from www.cooltechnica.com instead. They sell Swiftech, Dangerden, and DTek stuff so you can pick and choose. Also Bruce is FAST to respond to questions and ship; Dangerden can be a bit of a challenge to deal with via e-mail sometimes.

[RedPhoenix]

Cool.. But 1 question. Wouldnt the 1060 be better than the MCP600 because the flow rate is more than 3 times the MCP600?

[pHaestus]

No the free flow (no restriction) flow rate doesn't matter. What matters is the flow rate a pump can achieve with all of the waterblocks and fittings and radiators and hose in the loop. The MCP600 does a better job than pumps rated for much higher max flow rates. See a comparison here:

Wow, interesting. So you would recommend the Hydor L30 over the Eheim 1250 then? Seeing how the MCP600 from cooltechnica cant be done becaseu I need to get everything from 1 store ( as you know) and maze4-1 gpu does not exist. So Ill just got with the DD pumps they sell

Hydor L20
Hydor L30
Eheim 1046
Eheim 1250
Eheim 1060/1260

Which would you recommend for the setup I plan to get?

[RedPhoenix]

bump

[pHaestus]

Out of those pumps I'd get the L30. It's MUCH smaller and cheaper and performs as well as the 1250.

[RedPhoenix]

and that should be effective to move water through my setup? One more thing, on my rad, it has a 5/8 barb and a 1/2 barb. Which should be the inlet and the outlet, to make it more effective of course
Thanks for your help

[satanicoo]

bigger inlet, smaller outlet.

[#Rotor]

the inlet/outlet size does not make a difference, in how the rad will perform... go with the config, that's physically the easiest for you...

I can imagine, since you are going to split the line, after the radiator, to have the outlet on the 5/8 fitting. would make things smoother.

[fhorst]

Well, I get quite a bit confused about this.

Splitting is deviding the water in 2 (not equal, as the presure on the splitted side won't be equal). To my knowlegde, you should get as much water via the CPU block as possible. More water is better cooling.

On the other side.......
The waterblock restricts the flow, and leaves the pump capacities way behind of what it is actual able to perform.

To split the outlet of the pump, this would be improved ( a lot).

but as the water goes in the way of least resistence, the waterblock will lose some gallons/litres of water flow.

So what's the best setup?

[#Rotor]

the biggest problem with multi-block setups, is the fact that the secondary blocks, I.E.. those that are not critical as far as there performance (chipset, NB, HDD... etc) , are high flow blocks(low flow resistance). This forces one to have to use them in series with the CPU-block (block#1), and in doing so unavoidably affecting block#1's performance in a negative way.

By having secondary blocks with high flow resistance, one not only makes sure that block#1 get what it absolutely has to have, one also insures that the pump is utilized more efficiently. Parallel systems are a lot more involved, yes.. but unfortunately, as with most things, nothing is for free....

I never run multiple blocks in series. not even SMP cpu blocks.



Always at least two legs, with one/Two of them exclusivly optimized for the CPU block/s. All other legs are secondary in nature and are to have a relative high flow-resistances, at all times.

[RedPhoenix]

Very interesting #Rotor... Do you also recommend the L30?

And do you have recomendations to make the other legs higher flow-resistnce?

I'm dealing with:
CPU (1/2" ww),
NB (1/2" Zblock),
GPU (3/8" inovatec),
3x HDD (Koolance 6mm (inch?)

Maybe I'm a bit thick today.......

I don't understand about the "High Flow" 2nd block, being worse for the CPU block than a "Low Flow" block, in series.

My setup: Pump->HC->CPU->GPU->Res.
DT WW, MCW50.

Are you saying that a more restrictive GPU block like a DDM4
is better than using the MCW50?

I don't get the logic in that

I figured for a relatively restrictive block such as the WW,
having a "H-F" low restriction GPU block would be best.
In that, after the water leaves the CPU block, it wouldn't have to push through a restrictive GPU block, then into the resevoir.

I wanted the GPU block to have as little impact on my flow as possible, thus the HighFlow MCW50.

I was musing: what if the DDM4 GPU block is more restrictive than the DT WW? I thought it would lessen the flowrate to the CPU block in that scenario.

Am I on track? Please explain your reasonings so I can understand.

Thanks!

[edit] upon re-reading your post, you're only proposing this in the paralell, serial scenario. If this is so.... disregard my post.
