Running multiple Pumps?

[cluelessgenius]

is it possible to run a loop with multiple pumps? wouldnt they hey to be the exact same speed? what if one runs faster it would suck water faster then the first one could pump it ? wouldnt that be like having 2 different speed engines in a car?

it just adds more points of failure in my opinion

Its possible, no real benefit in temps as one pump is more then enough flow for your loop, but its nice to have incase one breaks your system will still function. As for the question about different speeds, I'd probably run them at the same speed to be safe but I don't imagine any real damage would come from it.

2 pumps at the same speed is being done. there are even things like this to make it more compact: http://www.ekwb.com/shop/pumps-and-accessories/pump-tops/ek-d5-dual-top-g1-4-csq-black-acetal.html you put 2 pumps on this with a single top.

[.:MARK:.]

When you are doing this, be careful to allow all pumps to pump properly and never allow them to be in the situation where there is no liquid to pump. This causes harm to pumps.

my worries exactly but i guess one pump alone would struggle with lets say 6x 480 rads (i know its crazy but thats not the point, im doing it as a projekt so wether or not this is practical or overkill is not subject of discussion)

well how musch rad space would you think is max for one pump?

yeah ive seen those youre right it seems as it has been done but would would be the max for 2 pumps how much rad space could i power with 2 pumps?

what exactly do you mean? isnt there alway water to pump given there are no airbubbles?

IMO just run separate loops than two  pumps in unison. 1 loop for cpu(s) and 1 loop for gpu(s).

 

Even then I prefer one loop with a strong pump. Keep it simple.

Multiple pumps work together to pump the liquid so I think running one lower than the other would just mean that one is doing more work. If you want to do this worry free, I'd say just buy two of the same pump like two Swiftech PWM MCP-655's and control them at the same time with a Y-splitter on a dual pump top from Bitspower or EK. Don't forget that rads aren't the only things that decide how many pumps you need. So are waterblocks and the amount of fittings and tubing. I can't tell you how much one D5 can push for example. I have seen one D5 on a triple GPU block + 2 480 Rad setup, hopefully this provides a good reference point.

Yes it is and has been done may times. You can have two pumps in one or two loops if you desire.

Not at all, it promotes redundancy in single loops which is a good thing in watercooling.

What exactly do you plan on cooling with 6 480's? If you have that many components to cool, a dual loop is probably a better option, GPU's in one, CPU in the other. 

 

What case are you going to buy to fit 6 480s? Nothing besides a caselabs tx-10 comes to mind

 

It seems like you're either spending money to waste money, or one of those people who asks 50000 questions about high end parts / setups and never actually does anything.

the plan was to be able to cool stuff maybe passively. Casewise im gonna build my own on that you can count but youre somewhat right as some of my questions are of theoretical nature im asking those to widen my spectrum and check out different options im obviously not going to follow up on all those but here are the things im definitly going to do in the near future: im gonna move, buy a new mobo and cpu(preferebly with waterblocks available), build a custom case after some renders im doing either out of glass or maybe acrylic because its easier too work with, then finally watercool the whole thing after i filled it up with rad and since im building the case myself i can kind of play around with sizes and ratios too make basicly every piece of equipment work. then im finalkly gonna get a new monitor as prizes will hopefully have dropped at least a little bit. and the last thing im sure of is getting the new nvidia flagship when it comes out and watercoll that too to finish my build

 

all of this is expensive yes but im not locking for a place to burn my money. a quality case and qtercooling setup will last for years too come so im taking a leap and realize a dream of mine .. sue me. also im not ashamened to say that i do reasonably well in life since i worked hard to get here. 

 

to sum it up id say yes i do ask a lot of questions some of wich redicoulus and im not gonna act on all of them but im just checking out my ioptions in eaöizing a dream of mine so again .

martinsliquidlab.org has a great article on multiple pumps both in series and in parallel

[skline00]

I have Twin D5 pumps in series mounted in my XSPC Twin D5 bay res. Great flow rates especially with using the external MO RA3. Candidly a single D5 is enough but I wanted to try 2 D5s in series.
