In a very limited, expensive sort of way?

i think it's for people with massive amounts of hardware to be cooled more so then better flow for a small loop.

man i really wish i went with ddc pumps... dam d5's. anyone want 2 plus a d4?? only asking 150!

lol.

in 6-year months i will buy 4 swiftech MCR420's and keep my triple triple's and run that pump setup:)

Damn, just buy a RD-30. A little overkill! :ROTF:

I laughed when I saw this - I just ordered the dual top yesterday after reading skinnee's review. Was torn between the XSPC dual and the Water Cool dual, but went for the cheaper, simpler look of the XSPC.

Happy to see new products coming out, even if I'm not sure it's something I'd use, it will be fun to read the test reports.

I like my pump tops the same way I like my women I guess :shrug:

I actually rolled around on my bed laughing at that "can I kill you" comment.
This top is awesome, if excessive. If I wasn't so convinced I need to go dual loop, I'd be looking at something like this or the dual to go through all of my blocks.

We're still talking about the pump, right??

But seriously, waterprOn though it is, it wont even go in a drive bay!
Would'nt it have made more sense to have mounted the outer 2 pumps vetically, so you end up with a cube of perspex, with a pump on each of 3 of its sides.....
IOI
......If that makes sense.....??!!

Great, and I just ordered 2 more MPC-655, wish I have hold off the order

Would be nice a top like this or the dual for d5 too :up:

D5 have lost attention lately :(

would probably perform on the level of about 1.5 times of a single DDC in terms of pressure/head

In series each DDC will add about 30% increase in head pressure. so roughly 1.7x the performance of a single DDC.
this is of course not at all respecting the 90s and heat dump.

Hey guys ... just a reminder - we've got minors reading these threads so let's keep everything family friendly. Thanks!

oh really...

I think you meant to say 30% more flow.... :yepp:
I think the math works out to be 30% more flow..

The approximation I use is as follows:

When going from single pump to dual pump (identical pumps), you can expect roughly (X * sqrt(2)) for flowrate, where X is your flowrate with single pump. Works out to a ~40% increase in flowrate.

You can apply this when going from dual to triple as well as single to triple, either (X * sqrt(1.5)) or (X * sqrt(3)), depending on what your starting point is. From a single pump, that works out to a ~73% increase in flowrate; from a dual, that works out to be a ~22% increase in flowrate. What those flowrates mean for you thermally varies on your setup....usually the gains past dual DDC are almost non-existent, heck, going to dual DDC can hurt if you don't have enough radiator or if you block is blind to flowrates (some have a pretty flat response curve).

This is simply one of the most moronic things I've seen as of late. :shakes:

I'm sick of working the day job for the day, it will be there later. I'll finally reply with more than an emoticon since I can put a little thought behind it now. :D

You already have my death in motion, look at all the cursed parts you send. :ROTF:

Yes, I have 3 DDC's and your D5's haven't even tasted a drop of the high quality Roundy's Steam distilled... they've been sitting in a box since they arrived. I did get a production sample of the Dual and Triple tops, I thought Paul was just joking around about the triple until I opened the box last week and there she was.

From the preview of the XSPC Dual top, I wasn't happy about not having the power data and needed a new bench power supply. Well, I finally found her or her sister... Mastech HY3020D or HY3020E. I can't decide between switching and linear, because I really don't know the difference or what it means for the bench. I have a linear now, but could I save the $40 on the switching 0-30V, 0-20A?

Anyhow, yeah I'll have full PQ's with power consumption on the XSPC dual and triple tops with individual tops in series. Eric has the EK Dual which he will be sending out, but I only have one EK V2 so I can't compare that to its individual top equivalent. Like normal, the comparison page will be the eye chart plots. The only other top I have is an XSPC Res top, which I have the PQ just never released it. Almost done with the large radiator update, and CPU block photos are being imported and saved for the round-up.

At least, thats what I have planned for now and what the hold up is. :p:

seriously, that's just ridiculous now. i can see a reason for two pumps connected, but with 3? might as well make a top that connects 10 of them. we all know how doubling on the pump does not double the flow or head. and on top of that, we've all seen how increase in flow after a certain point hardly does anything to the overall temperature.

and autobot's picture looks dead on. makes me think they were too lazy to even try to think of this or redesign the water routing. 90's certainly don't help the flow, but someone mentioned that it didn't do much to the performance? well duh... that's because there's TWO pumps on there when it was tested in dual pump. if they had designed it like how autobot drew, the WORST that can happen is that performance is the same as if those 90's were there. most likely taking out four 90's will only benefit.

i really wonder if having 3 pumps will actually raise your overall temperature and give you even worst performance. there's a lot more heat dump from the pumps, while flow will not even triple. even if it does triple, flow hardly affects temperature like mentioned earlier.

just to get this straight without starting anything... are you sure?
how can there be more flow if the pumps are in series and all impellers are moving at the same speed?

now if they were in parallel, then there would be more flow as the water path get divided into three, with each third being "moved along" individually (as individual as it can get in a closed loop:p:
am I misunderstanding this?

would this give you much benefit over just hooking up 3 pumps in series with tubing?

If I wanted this kind of flow, I would go with an Iwaki.

Its pretty much the same thing. You may get a little better flow as you could get rid of all those 90s before and after each pump. Seems Skinnee is going to try testing it though.

Yes im fairly sure... the last number we talked about tho was near 30% i think.
I got bit in the butt when i challenged scott to this statement, and he showed it to me.
That's why i know...

And vapor said it best...

so you think all the 18 watts of power is wasted as heat, and then dumps it all in the water...?

then what is turning the impeller? if all heat/energy is absorbed by the water, why is the outside of the pump hot then?
