Dual pump question

2460 Views 21 Replies 6 Participants Last post by  Wadkiller
Hey guys!

I got a freaking awesome deal today. Got me a Swiftech MCP655 for cheap.

Now i don't know how to run my loop. I thought i could go dual loop, but the space in my antec 900 won't accomodate this (i think).

I've got 2 options.

1. Run my pumps in serious. Like this. res > laying ddc > mcp655 > MCR220 > HK 3.0 LC > MCR220 > MCW60 >res

2. Try & run a dual loop, but will i be able to run both of an ek 100 res?

How much will it affect the flow if i run a dual loop , but use one outlet from the res split with a Y fitting to feed both pumps?
run them in series, the pressure is used more efficiently. probably even when using those 2 different pumps, as the pressure ratings arent too different, and the flowrate trough the system is probably still lower than the unrestricted flowrate of the DDC.

Thanks guys. I'll probably build me a proper rad housing in the June holidays & run a dual loop if this is'nt what i expect. I'll setup my stuff next weekend, got some studies to attend to first.

CS, got the stuff i ordered from Aquatuning yesterday. The HK looks awesome! Can't wait to get all the stuff in my rig!
doesnt it? You meaning the performance of my current setup? or the looks of the block?


No i'm happy with my current setup. Just don't know what to expect with the dual pumps.

Soz for the double post.

I don't know if i'm jumping the gun here. Will this actually improve temps? I'm buying the pump anyways.
If you don't need two pumps then don't use the second one. It will add heat to the loop that the RAD will have to get rid of. If you need the second pump for the added head pressure then by all means use it.
Another thing i don't have any knowledge about is the pressure part of the graphs on the flow estimator martin made. Is more better? The amount of heat i'm currently dumping is minimal so the added heat of the pump will have barely if at all affect my temps.

I've got 2 blocks & 2 rads in my loop & according to martins' flow estimator i'll have great flow with the dual pumps.

When I run dual pumps I always run them one right after the other and the same kind. Running a D-5 and a DDC I'd seperate them the way your planning.

Pumps in series will give you twice the head and about 30-40% more flow.

I dropped a a C or two going to dual 18W DDC in series from a single 18W DDC, in a CPU only loop, I'd think you would get a little more in a multi-block loop, maybe. Those were the old high performance orange impeller 18W DDC. The redundancy of dual pumps was a nice thing to, if one dies the second will keep right on pumping.

If you were going to run a dual loop and just use that one EK res you would still have a single loop since the water would mix in the res, the hotter loop would warm up the cooler, which should be the CPU loop.

If you want to run dual loops just use a t-line on the second loop to save room.

If I were you and since you'll be buying the D-5 anyway is to just try it both ways and see what works best for you , dual pump single loop or two seperate loops. Thats half the fun with this stuff, playing with it.
.Try it one way for a few months and when you get bored with it try it the other way. That way you'll know for yourself which way works the best for you and your config.

Thanks Ira!

I'm going to run one loop for the time being, so that i can get that HK 3.0 LC on my cpu. I'll definitely build me a rad box in the June holidays, just got a crap load of studies to attend to.

I just need some ideas on the rad box, cause i have no idea as to where to start.

NP.
.What kind of tools do you have? You could make it out of wood or metal.

Aluminum angle bolted or pop riveted together for size with hex mesh inserts would probably look pretty sharp. You could paint it any color or just leave it silver. These guys have some sharp mesh..DragonModz Shop .They have the diamond, round,hex and oval. I bet the oval would look pretty good and everyone doesn't use it.

You could make one out of wood like that to. Or use some aluminum coil stock and use that to cover parts of the wood or aluminum angle frame to, solid and then mesh for the openings.

I have a drill & a dremel. Will probably get me a jigsaw when i start to build this thing. After the things i saw that Syrillian made with acrylic i'm really keen to do something with it aswell.

Yeah Syr does good work in plexi, CD to. I suck at it, I'll get something about 90% of the way done and I'll crack it out.
.I mess wood and metal up to but I can usually fix that.


The newer poly carb and acrylic aren't supposed to crack out as easily, I've never used any of the newer stuff.

They have saw blades and cutters and other tools for it here if you cant find any locally.United States Plastic Corporation ®

You definitely want to pay a little more and use Polycarbonate it is much tougher than regular Plexi.

Thanks again for the info guys. Luckily there's a few local places i can shop @ for these things. I'm just having trouble thinking of a design & how i will make evreything fit.

I'm thinking of making the rad housing big enough for 2 - 360 rads. Their probably going to be mcr320's. I think it's going to look funny with 2 different pumps, but i just could'nt pass on the mcp655. If i had to import one i would've payed +-$130 us.

If i make this, it would probably be the height of the antec 900 & the lenght. I want a good clean looking housing.
Hey guys!

So i received my D5 today & guess what it's the vario. Just made the deal that much sweeter, cause i was under the impression i'm getting the stock one.

I Was thinking quite a bit about the rad housing i want to build & i was having trouble to get my thoughts into some form you guys will understand. So Syrillian suggested Sketchup (thanks for always helping m8!). Now i'm not really sure what i want to do. I have 2 options.

1: i can make sort of a clone of the antec900 which will double up as a side cover for the right side of the case. It will have the same dimentions, 45cm long, 20cm wide & 42cm high, i will not replicate the plastic cover of the top of the antec900. I will also make a super long dual res that will fit the front end of the rad housing. I'm not sure if i will make it a dual 360 rad housing (i will use 2 - mcr220's for the time being) or a tripple 360 housing. The rads will be placed horizontally, so that the tubes align with the blocks, top rad/s for cpu block & bottom rad for gpu/s.

I will try & get a design up ASAP.

2: my 2nd option will be to make something similar to what Cyberdruid did with indignity's antec900 . (awesome work btw) Mine won't be anything like his. Not that don't want to, but becasue i don't have the skills most of you guys have.

Lucky for me my dad's partner builds huge ovens for bakeries, so he (my dad) will do most of the manufacturing , casue i'm no where near him & i don't have the tools. There's lots of spare materials (steel). I'm aware that this will weigh halve a ton, but it's for free & i'm strong.
I The 2 rads will be fitted to the sides, each overlapping each other so that i have enough space to fit the pumps aswell. I will also make a dual res that will fit in 2-3 5.25" bays. Or i can get another Ek100 res. This option will require the least work.

Both options will be powder coated. I'm starting to lean to option 2, not because this will be easier, but it will save alot of space & be alot cleaner looking.

PLZ guys, let me know what you think & suggestions are welcome!

I'd separate the pumps from the rad if you can, they throw off a lot of heat in a enclosed space. But you'll have the rads pulling air from the outside in so that will alleviate a lot of that heat.

How did CD make that? Was it a rad box or did it attach to the case. He makes so much stuff I cant even begin to keep up with it. Link me if you can.

You could just make a rad-box thats like a phase rig, the case sets on top of it. A lot of guys used to do that when they were using Bonnies for rads.

Powder coat it the color of your case and it would look sharp.

Ok this is bothering me again. I'm expecting my Lian Li any time now. I'll be able to run a dual loop easily, but would'nt using 2 rads in a single loop be beneficial for my temps. I mean, my cpu/gpu will never be loaded 100% at the same time. What pump will you guys use with one loop? The ddc or the D5?
