Quick question on pump choice.. dual or single?

[eclypse]

Trying to figure out if going with a dual laing D4/D5 pump will be ok on a loop with a EK Supreme HF (Nickle top) w/plate #2 and EK EVGA 760 MB WB??

I have a single pump on that line now with a ThermoChill PA 120.3 rad and the flow is seriously turtle! Wondering if adding another pump in series will be too much pressure for the pumps or EK WB since its so freakin restrictive or will help with the flow?

Another option i would'nt mind doing is just sperate the 2 blocks and run a pump on each or possably just leave it as so with a single pump on the loop.

Was looking at possably buying all new pumps but holy cow the cost for 4 DD 3.25 pumps and 2x EK dual pump tops! So i guess i'll try it with my current 3x Laing D4 pumps.

I don't think you should worry too much about pumps; one should be plenty. You say the flow is turtle, but how are the temps?
If you're just using one radiator then one pump should easily be able to handle it.

I don't know about the D4, but any of the newer pumps will handle that system fine.

Burp! Come on guys.. give me some feedback.. i need to get the order in so my new case dont sit and collect dust for days waitin on parts.

What waterblocks gonna be in that loop? Only HF + motherboard full cover? Then imho even one D5 should be enough even with most restrictive plate #1. If flow gets too low, then something else is wrong/causing restriction. Check for gunkup with debris microfins of HF (maybe some flux leftower washed out from your rad (Thermochill PA rads are known for such issues and usually need thorough cleaning even when bought anew), check if you haven't mistaken HF inlet order, check if somewhere there isn't some kink in tubing, check if whatever you use for flow measurement is properly calibrated and gives you right flow measurements.

Yeah, the HF and PA are really low in restriction..not going to gain much at all with two pumps. Suprised you say flow is low...should be pretty healthy with a single pump. I wouldn't bother with two unless you just wanted redundancy or for extremes.

Temps are fine but wonder if they could be better if the flow was up.. you can barely see the water move in the res.. unlike the same res and same pump with the loop runing threw dual DD 480GTX blocks in parallel. The water is splashing all over the place.

I figure its the EK Supreme block thats seriously killing the flow.. Thats why i figure runing dual might get the job done but wanted to ask as with the high restriction of that EK Supreme block it may not matter..

Maybe i should run the CPU and MB blocks in parallel as well?

If you have excel, give this a try..it should give you a rough idea of what the differences would be between one vs dual pumps....http://www.xtremesystems.org/forums/...d.php?t=151627

Fairly new system as in couple of week old.. Clear lines with only distilled water and kill coils in the res. The in on the right and out on the left (label facing you) of the EK Supreme block. I'm using a XSPC Acrylic Dual 5.25" Bay Reservoir for Laing D5 http://www.performance-pcs.com/catal...ducts_id=27998 on both loops. Maybe thats helping with lilling the flow as well.. but like i said i'm also using the same setup on the 2 DD 480GTX blocks and shes fine.

I also flushed the crap out of both rads before using them with boiling hot distilled water. The water is clear.. though i guess it would'nt take much for that plate on the Ek Supreme block to get clogged if something did come out of the rad.

The Ek Supreme plate is the one with the 2 thin channels cut into it. Dont know if thats plate 1 or 2 as the directions that came with it are pretty faded. Maybe its out of place when i put the block together but you would think it would flow even better if it was hehe.

Too bad i dont have that.

If someone could run that for me its a loop with:

1/2" ID 3/4" OD tubing w/ 1/2" ID barbs.
Ek Supreme HF Plate #1 i beleive.
EK EVGA Classified MB water block.
XSPC Acrylic Dual 5.25" Bay Reservoir for Laing D5
Laing D4, i believe its about equal to a Swiftech 350 pump.
ThermoChill PA 120.3 rad w/ 3 120CFM fans.

note - if you don't have office/excel, you can download openoffice.org which is free and gives you much of the same compatibility.

If your temperatures are fine then don't worry about the flow :P
If you still want to worry about the flow, replace the D4 with a D5 and check the system for gunk like churchy suggested.

Downloading that excel program now.. slow download

Yeah, i could order a new D5 pump as i was planing on runing 2 dual pumps in the system anyways.. but was originally thinking of grabing a 355 or DD 3.25 DDC pump since i thought they were better and quieter. :/

Prob just grab a EK dual D5 pump top and a single EK D5 pump top for the 3 pumps i have now as it would be cheaper to do.

I'll find out soon if anything is trapped in the EK Supreme block as i'll be taking it apart (maybe, as i'm afriad to break the o-ring as its such a bish to get back together soon enough when i get the new MM case.

[afireinside]

DDCs are anything but quiet. They perform rather well though.

I put everything in the spread sheet for you. With a single D5 on setting 5 you will have 1.47GPM. With two D5s on setting 5 you will have 2.01GPM.

[eclypse]

Thanks.. yeah i've been playing with that excel program thingy.. Seems like the only real easy way to get the flow up is to use seperate loops for the MB block and CPU.. but i'm sure thats overkill. Its at 1 GPM occording to the spread sheet with my current setup.. i bet even worse with the pump face/res i'm using. I'm using the Laing D5 P4 or basic model since i'm really runing a laing D4 pump.

Thanks for the info on the noise.. yeah. i really should wait for the new pumps from Swiftech that are on a vario.

I guess thats how everyone is using them though with both blocks on a loop so i guess its fine.

[eclypse]

Occording to that spread sheet i could run a single loop using 2 laing DDC 3.2 pumps in a eK dual pump top at 1.83 GPM for my whole system:

HW Labs 480 GTX and ThermoChill PA 120.3 rads and 3x DD 480GTX blocks, EK Supreme HF block, EK Evga Classified FC WB!

Thats nuts when i could'nt get that kind of flow with a dual D5 pump setup just going threw the single PA rad and CPU/MB blocks. Also i only get like 1.17 GPM with the single D5 pump through the CPU/MB block! :/

Damn!

[eclypse]

Damnit.. theres no option for a D5 EK Dual D5 top to add to the loop in Skinneelabs pump/rad optimizer.. Kinda tough to know how much better it would be just runing 2 D5 pumps in series with defualt tops over a EK Dual D5 top.

Not exactly, but you can use a single D5 in pump 1 and another in pump 2 to get an approximate estimate. The difference between stand alone DDC vs dual top DDC performances is pretty small.

I think Skinnee is still planning to do the dual D5 top though, so it'll probably be added in later.

[eclypse]

Thanks guys.. i think my wife will thank you as i believe i'll just skip the pump tops all together and just run them default for now till something better comes out.. that way i'm not wasting money in the mean time.

BTW.. Is there a good tube res out there?? Been looking at the EK Multi advance res.. mainly cause of the anti-typhoon insert. hehe. Good or dont bother and just grab a old Swiftech micro res V2?

[terente0081]

I use multiple pumps mainly for redundancy and because this is xtremesystems, this is how we like it ) Pics attached, enjoy!
I do have some restriction in the loops, I use 3 DDC Ultra pumps in the CPU loop but I have 2 Feser 480 rads in that loop as well. Temps are well in check and there is plenty room for more overclocking; and the cooling system is futureproof this way.
This case with all the rads, pumps, reservoirs and tubing is like a huge cooling system that I mount the PC in.

[rioja]

you are mountain mods killer

[iddqd]

next step: build a case entirely out of radiators. you're already halfway there!

[MagisD]

Personally I like and am useing the koolance top and direct attach res there nice. Ek has the same in single and double D5 tops
