You're not wrong.

dude i still wish i had my video...

But i actually connected my RD-30 to a bucket and then let it rip on full to see how high the steam went.

It went in a nice pretty arc to my neighbors yard... lol..

He was wondering WTF i was doing that shot water up that high.
My neighbor was cool about it, and then he started to play with it...

sounds funny :) a buddy did a test with a sanso pump outside on a housewall - it pumps 8 meters high

LOL! The water in the reservoir sounds like someone frying bacon.

Alacheesu is right, height difference does not matter in a closed loop. The pressure you loose on the way up you get back on the way down so to say.

But it would likely be a hell to get a loop started if the internal height difference where larger then the pump head. And you would possibly get cavitation problems on the highest part due to low absolute pressure.

I was making a joke, a poor one, but still a joke because of the amount of head this thing would have. Also, for the love of god people, please learn to type "lose"

no, not at that length.
The raw length of tubing would add to restrictions.

So its not going to be a perfect cancel out of kinetic vs potential.

Because the friction constant of the tubing @ that length will be significant.

This moronic top is now available. :rolleyes:

The only reasonable application for the triple top might be if you are using a load of Koolance quick disconnects.

Though why you would be using so many is beyond me.

Either that or 2 EK supreme's in series

Eh, i have 2 sets of v4 quick disconnects in each of my loops and there is very little difference in flow compared to before.

Do you have a flow meter?

Because Hondacity measured .25 gpm flow loss for each pair. On the average restriction loop (GFX FC, Apogee GTZ) two DDC's wouldn't even reach 2 gpm.

That was the VL3s. The VL4s should be better than that, although I can't say how much better.

The VL4's simply have a wider ID - to use it with one half tubing with a converter to use standard G1/4 barbs (not G3/8 which they are) kind of wipes out the difference the wider ID makes.

I'd bet that restriction is similar to what Hondacity tested in the VL3's.

QDC's... :wasntme:

hmmm.... ;)

As for the DDC testing, new power supply should arrive on Saturday (silly FedEx Domestic). I moved a work outage to friday night so I could start testing on Saturday. :)

Did you just get that up, Skinee?

Still working on the review and test summary, finished the testing last night... there is a little something ore than just PQ data. :)

Am seriously looking forward since I have VL4's lying around here :)

Are there any waterblocks to use on the pumps? :ROTF::cool::p:

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.

Hey everyone, I'm kinda new here on xtremesystems and just had something to say about the XSPC Triple Acrylic Top. Many people argue that 3 MCP355's will add a lot of heat into the system but what if you were to undervolt the pumps for maximum flow vs. noise?

I myself am doing my first watercooling setup using three MCP355's because my setup will be very restrictive. I'll post a thread with my setup and am hoping for lots of suggestions xD

3 MCP355: 3 x 18W (max power consumption) = 54W.

The maximum heat dump can never exceed the maximum power consumption. A lot of the energy gets converted into kinetic energy, the rest gets dumped into the water as heat. I'm not sure what the actual heatdump of a MCP355 is, but I don't think it's nowhere near 18W. So even if it would dump 18W, it still isn't that much (CPU and GPU usually dump double that when under load).

Nope. It's just madness. Maybe close to blasphemy, but it's definitely not SPARTA.

I just wish I had 3 DDC3.25's to get PQ. Only have two so the triple top won't be included in the upcoming round-up, only DDC3.2 info will be available on the triple top.
