DDC3.2 Pump Top Shootout! 10 tops tested..

[Sparda]

damn custom stole my money My packet just arrive for from Sidewinder for my second loop but being hold at customs. Sidewinder have great customer service

[Martinm210]

Wow, truely impressed here martin. Have you considered designing a top of your own. I think you've got soem great ideas for improving the design. Especially the idea of the angled/tapered inlet. All of my flow experience is in airflow but, the theories are quite similar. If the inlet was tapered from 1/2"ID to match the internal diameter of the inlet barb down to the impeller inlet with a slight radius to get the water moving into the farthest point in the pump from the outlet it should maximize efficiency and increase the velocity of the the flow.

Heck, maybe I'll make one

I've always thought of tinkering just to see what I could make, but I've learned my lesson over trying to fabrication stuff on a manual mill. I've yet to make a block where I've even made minimum wage...paper route is more profitable..

I think the next bit of tinkering I'm going to do is with some custom nozzles for some pump tops possibly the D5. I figured if I can find some good tweaks to existing designs, I'll send my thoughts to those manufacturers to consider for free. I'm not in this for money, I'd be happy just knowing some of my ideas were being used. The manufacturers have the means to make these things...I don't and I don't want to either. I do just fine with my regular engineering job...this is all for fun.

Martin you are awesome! Thanks for posting up the D5/MCP655 results! Ill try to send you a donation once i get some extra cash! I really appreciate all your hardwork!

Hey how did it go with the German customs what u got to pay the 19% or nothing???

Actually it about 20%. Yea I must pay the tax. But you can reduce it.....if you know what I mean...lul

edit : Usually your items will not arrive at your home because they hold by customs at their office. Then they send you a letter to pick your item and pay the tax there. So no use using express delivery because your item gonna arrive late than 5 days anyway. Better use Priority Mail.

XSPC Res Tops

Get 'em while they're hot

Finally - I ordered 2 - From Hank and Gang!

[dubleskillz]

Can you tap the XSPC res top to accept G 1/4'' fittings?

I love how PPCs posted up Martin's graphs.

Well, it comes with 2 G1/4" holes already in it....and if your talking about putting in new ones, I don't think I would try judging by the pics, it looks like it might be a bit temperamental about having new holes drilled in it.

I love how PPCs posted up Martin's graphs.

Bah! The thing with Hank is, he basically copies the Manu's product page and fits it within his page layout. Follow the link at the bottom of the page and you'll see what I mean.

What barbs do you use on the XSPC res top? Ie it ok to get the ones from Performance PC drop down list?

I think just about everything should fit on the reservoir, you just need to keep short threaded types on the regular top. D-Tek barbs were the only ones that wouldn't fit on the regular XSPC top for me, but EK barbs were just barely short enough.

There has been one case of larger than normal DD barbs that didn't fit for someone else, but all of mine do. It's a standard G1/4 threading.

Did you give him permission Martin? If not, that seems a little...uhhem, rude to say the least....

*sigh*

Hank did not take the graph from Martin, he took it directly from XSPC's site. The page I linked to on P-PCs is like 98% copy/paste from the following page.

I'm actually happy to see the interest, anytime I can have some sort of influence in real data showing up instead of marketing headlines, I'd consider that a success..

No problem..

[Martinm210]

BTW,
I recieve two new tops from Bitspower today I'll be testing and working into the existing results. I've got their mini reservoir top and the regular top.

I also got some 3/8" BSPP barbs from our generous friends at www.watercoolingshop.com, so now I can test the EK G3/8 X-Top.

If OClabs follows through on the xptop, that'll be 14 total..

XSPC Res Top now also available @ FrozenCPU.

It's also @ Jab-tech but is currently OOS.

Great test, just one regret : the OCLabs XPTop is not included :/
Here it is : http://www.sidewindercomputers.com/ocxpforladdc1.html

It would be nice tu know how this one perform, since it's cheaper than XSPC's (only 17$)

Another question : Will the charts stay unchanged when using DDC1 9W? Is the best top for 18W still the best for 9W?
Thanks

They said they are sending me one, Sidewinder said they would help me out to so I should have that one tested as well sooner or later.

And I don't know on the 9W pump for sure yet. Planning to convert my pump over to the 9W with the solder modification and run the same set of tests for that pump as well.

I would think the relative performance would be the same (Pump is exactly the same now except under volted), but I want to test it to be sure. It would also supply the curves for the estimator that way and be a second check on the original series of tests.

Great news!
Waiting for round 2...
Thanks

[Kayin]

I'm gonna make you a DDC top to test, Martin. PM me your addy and it should go out on Friday.

[Martinm210]

You have PM.

BTW, didn't get to the rest of these pump top tests just yet, I was working on another pump, but I'll be back with some DDC 3.2 updates pretty soon.

Martin, I know you've got some cabinets to be working on, , but how do you think a 90° barb on the inlet of Petra's top would affect it? What about the same for an XSPC top?

[Martinm210]

Not good, but probably not nearly as bad as the side inlet results I have posted. Alot of it will probably depend on the type of elbow. If you used a 3/4" Q-Pex Brass elbow with just enough tubing to conect to a normal barb on top...probably alot less loss than a 1/2" nylon elbow.

I don't have any male to male connectors right now, but I figured I'd try a delrin elbow for more of an extreme space need run and maybe one with a 3/4" brass or copper elbow. I could make some, but I'd rather test with commercial parts and I just need to order a couple.

Anyhow, I'll get to that question after I finish up some new product tests and the 3.1 tests all done.

@Martinm210

Do you know if the XSPC Acrylic Reservoir DDC Top can be used on all versions of the DDC pump as the original Black impeller is a different size to the new blue impeller pumps ?

Can you explain more on the trouble you had sealing the top ? As in did the cap leak when fitted or you couldn't screw it down ?

Thanks
