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..:DQuote:

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.:D
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 :DQuote:

XSPC Res Tops
Get 'em while they're hot
Finally - I ordered 2 - From Hank and Gang!
Can you tap the XSPC res top to accept G 1/4'' fittings?
I love how PPCs posted up Martin's graphs. :up:Quote:

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....Quote:

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..:up:Quote:

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..:D
XSPC Res Top now also available @ FrozenCPU. :clap:
http://www.frozencpu.com/products/72...ml?id=YrGrogej
It's also @ Jab-tech but is currently OOS.
http://www.jab-tech.com/XSPC-Acrylic...C-pr-4123.html
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.Quote:

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.:up:
Great news!
Waiting for round 2...
Thanks ;)
I'm gonna make you a DDC top to test, Martin. PM me your addy and it should go out on Friday.
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.:D
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?
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.Quote:

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
I'll give it a try, I've been meaning to try couple out on my old orange impeller DDC2, I have a black impeller DDC also, but it's got a burnt chip and about to go, but if it works on the orange, it should work on the black.Quote:

I wouldn't worry to much about it in a normal system if your reservoir is mounted upright, but I wouldn't want to mount one sideways. I talked with XSPC about the threads, and my sample was previously used, so it's possibly I just got one that was partly damaged.:shrug:
FYI,
I got the EK G3/8" X-Top finally tested this evening. It turns out to be a decent gain over the G1/4 top which I didn't really expect. In the end it'll put it in about 4th place in most of the high/average/low restriction categories.
It seems the littl step and restriction at the inlet has proven itself in providing some gain.
Very good, I'll get this worked into the comparison.:up:

I hear what your saying about the top fill cap could have been mistreated before you got it but it's still a concern as people will fill and empty their loops more than once and if it wears like yours has then the res is pointless using if it's not hermetically sealed as your be forever topping it up or having to change the water when it becomes contaminated and turns to pondwater.

The old pump had a larger impeller inlet and the stock top and some of the custom tops incorporated an little nozzle that extended down from the ceiling of the pump volute. Unfortunately this does conflict with the smaller impeller opening of the newer pumps. So yeah, the old tops are not forward compatible, but all of the new tops should be backwards compatible. Not sure how performance pans out, the larger impeller inlet will likely have some performance preference differences. This is also probably why alot of the tops have larger openings for the inlets, they were sized good for the older pumps, but too larger for the new DDC 3.2s.
My XSPC dual bay reservoir pump uses the same sort of reservoir cap and does not have the same issue, so I'm inclined to think it's just a fluke as it was a pretty early copy. I also don't worry too much about a perfect seal at the reservoir or T-line. I've run my T-lines with a less than perfect seal for over a year without any sort of problem. Because the tubing stretches and expands under pressure a little, I like having a little venting to remove any pressure buildup in the system.
Like anything, if it's really an issue, that'll surface in the users voicing their opinon, and I'm the only one I know of that had a threading problem of the cap.
Then It's not a problem as i first thought.
Thanks Martin
Rob over at WatercoolingUK was asked about the res on the older pumps and turns out that it's ok :)
Quote Rob
"Yep, there is no compatibility issues on this top on any of the revision DDC pumps.. They are all compatible! "
FYI
I did a little experimenting with a slightly different testing methodology so I'll probably go ahead and retest all these tops one more time. I'm going to start measuring suction line pressures as (Total pressure drop) as well as move my voltmeter testing point to the pump plug. This will mean slightly stronger and more accurate results.
Me and my need for precision is my worst enemy.:shakes: Oh well, I'll get these all redone one more time, except for the EK X-res 140, I'll have to throw that result out since I don't have it available anymore to retest. I wouldn't expect any of the relative rankings to change, as they were all tested exactly the same, but I'll post a brand new set of graphs when I'm done.:up:
Has anyone used one of these tops? The outlet tube looks very large compared to the Alphacool.

I have both OCLabs Tops, it seems to be good, but i'm waiting for Martin's tests ;)
Here are some graphs from OClabs :

I have one of those now, so I'll get the xptop tested. A guy over on OCnet had two of the tops and both cracked on him. Not sure if it was just a certain batch or what though. I will get the performance curves established regardless.:up:Quote:

I wonder why the top cracked. Are you referring to the XPTop or the PlexyTop? I can understand the XPTop since it looks like it's just plastic but the PlexyTop is acrylic.Quote:

Completed retesting all the tops with the DDC 3.1, posted links and charts in the OP here:

Cheers!

Nice work Martinm210! As expected there are no changes in top positioning in the chart using a pump with less rpm.:)
What fittings did you use with the G3/8 top? EK G3/8 fittings?
Yes, all the other tops used D-Tek barbs. I did notice a slightly higher ranking with the DD top on the 3.2 testing, and the only difference is I used DD fatboy barbs in the 3.2 testing.Quote:

Wow Martin! I did not realized that you had finished your Laing 3.1 shotout!
Anyway! thanks martin for an interesting read once again! :up::clap:
I hope I can send something through paypal soon.
Just getting an old thread to live, as it is a sticky where the information has been lost. Did anyone get the curves and information from martin's page before he closed it? Without it, this sticky doesn't work to well ;)
