Test Report: EK D5 X-Top Rev.2

[Webby]

If he had bought it just to 'see' then that would've been fine if he admitted to doing that. But he blatantly LIED in saying that

"Also, we did not bought a top from you for direct comparison"

When you can see that they did.

No you are assuming they did.

That is not to say that they didn't but unless you happen to have proof that Eddy has a DetroitAC top you are making assumptions based on what has been said in this thread.

The fact that somebody in the same town bought one is irrelevant, interesting and gives pause for thought but it does not mean the two are related.

Wild speculation helps nobody.

If Eddy says he did not copy it and yes the are similarities but the are also differences then why should we question him? As somebody else has mentioned look at all the DDC tops they are all similar but slightly different but I don't hear everyone crying that they are all copying the Alphacool top (or whichever came first)

[theseeker]

Hold on here folks...before we gather a mob and stone someone to death, lets take a deep breath and look at the info we have.

I am not picking a side, I enjoy working with both DetroitAC and Eddy. All I can do is present the information I have, so lets see the two tops side by side.

Thanks Skinne, I was expecting a lynching.

[Sparky]

Looks similar yes but then how much variation can you have for a pump top? Not much

[nikhsub1]

Guys, the chamfer at the inlet is totally different, as is the spiral volute as is the exit... I don't see this as a copy at all.

[hellcamino]

I have just patented...the sock.

[Bojamijams]

Yes all explained.. except for the fact we have Eddy saying he didn't buy it and DetroitAC showing the logs from his store saying he did.. yes all explained.

[Eddie3dfx]

Yes all explained.. except for the fact we have Eddy saying he didn't buy it and DetroitAC showing the logs from his store saying he did.. yes all explained.

Well technically he said that eddy didn't buy it, but someone from that town did.
It could be another ass-umption.

[Sadasius]

Well looks like things got explained a little. Much of the info I did not have and thus made myself look like an a$$. Just looking out for a member who had innovation and when I saw the performance curves being identical and similar setup I jumped the gun. So Eddy....I apologize! Ignore my PM I sent you as it was written when I was acting retarded before seeing the evidence. The comparisons between the two have it's differences and as someone pointed out there are only so many styles to choose from and hard not to infringe on a similar idea or design. I guess DetroitAC can take it as a compliment then that his design helped inspire.

[Martinm210]

Thanks for the review skinnee, awesome work as ususal

[situman]

All manufacturers should apologize to Eddy for copying his full cover gpu block idea. He was the first to come out with it right? If not slap me silly.

[headala]

I'm just thankful that, after having a D5 for about 3 years, there are finally tops available that improve upon the base performance. Here's a toast to both DetroitAC and EddieEK....thank you both for your ingenuity and perseverance!

[Sparky]

I was kinda surprised to see so many here jump the gun so quick at attack him on it to be honest. I mean, we all know Eddy is a decent guy so it struck me as odd that everyone was so quick to judge him

This is the internet. It's practically expected that people will fly off the handle at the drop of a hat.

[warriorpoet]

Wow. Drammallama indeed.

Eddy's top looks significantly different in all sorts of ways. yes,his spiral-voluted design came out after DetroitAC's; yes, both are attached to the same pump; yes, both are black; yes, Eddy probably did buy a top to compare it (never denied it either, if you look at his actual words).

Here's what I have to say:

1. Great product, DetroitAC. Congrats on being the first to implement serious improvements in a product and bring it to market.
2. Great product, Eddy. Your stuff is always top-notch.
3. Amazing review, skinnee. Thank you so much for contributing to our community.

Sure, I can explain

Someone with the eBay ID: eddy_ek from Slovenia bought a pump top from my eBay store on Nov 11th ,2008 but never paid for it, so the transaction was cancelled many weeks later. My assumption was that this was you?

Then on Nov 13th someone named Peter Stampfel of Ljubljana, Slovenia bought one pump top with expedited shipping to Ljubljana, Slovenia.

EK Waterblocks lists their physical address as Ljubljana, Slovenia. These are just remarkable coincidences you will say?

To be clear, you have done nothing illegal or even contrary to normal business practice in my view. You have, however copied my work and this forum is a unique place, with an actual community in contrast to the "normal" commercial marketplace. I worked very hard to refine my pump top, and I hope the members of this board will choose to support innovators rather than hacks.

Hey Sherlock, before you start accusing everybody I want you to know, that I am Peter Štampfel and I bought your top for my personal use (and sent you back the item, for which I am still waiting to be refunded). Ljubljana is a city with more than 200k residents and I don't know everybody in person and as I stated in your inquiery prior to sending me the item, I am not affiliated with EK waterblocks.

[Dangals]

Great review skinnee - as usual you have done a fantastic job and made it nice and easy to follow

Bring on the next one

And that answers that question

[twwen2]

Awesome review skinnee, the machining looks nice and the pictures are exceptional.

Cheers!

But seriously, This is a dumb arguement/discussion, and probably wouldn't have sparked without vendor threadpoop.

This is a review thread. Please?

[Groveling_Wyrm]

Great review Skinnee!!! Thanx a lot!!!

Now to encourage some future possibilities

Who's going to be the first to put the DDC in it's rightful place and develop a pressure oriented impeller (something more like the RD-30 or DDC) impeller with longer deeper vanes that are more suited for pressure intensive applications like we have in water cooling???

I'm not sure the impeller upgrade is something that can be reasonably fabricated for a marketable price, but it seems to me if you could surpass the DDC performance, folks would be willing to spend a few bucks. I'm not of experience to understand the motor differences, but something still seems appealing about the D5 motor that is calling for attention. The weakest link in the D5 pump appears to be the impeller, moreso than the volute. Just look at that curve, so much power wasted at high flow rates we can never use. Just imagine the possibilities with an RD30 like impeller and one of these great new tops..

Iwaki very routinely designs one pump and several different impellers that go with that pump to tweak the curves. Seems like the D5 could be tweaked much the same. And that would be more than simple efficiency gains, that would provide the possibility to completely change the curve. Something with a large hump right 1.5gpm and maxing flow around 3gpm would do just fine...

Nobody has taken that step yet, what about that poor, always ignored, crying for help, IMPELLER!!...

Ok, enough...just wanted to encourage some future tweaks to consider. Impeller upgrades have simply been ignored in all of watercooling aftermarket parts and I'm just curious about it...

Cheers to the next steps in making this great pump even better!

Nice review! I haven't even implemented my X-TOP D5 Rev. 1 yet and I'm already considering buying the Rev. 2. Haha.

i would definitely reconsider the d5 if they improve the pressure... i only have the 355's for their pressure output

i'm not a designer.but if they can bring that 355 killa...then its certainly a

good suggestion...

[Waterlogged]

skinnee, It would be kind of nice to see what this gain in pressure has sacrificed in the way of flow. Maybe a quick test with a low restriction loop with both tops and then a high restriction loop with both, no temps, just pressure.

The only way I'd buy a "355 killa" is if it was the same size or smaller and cost roughly the same. The D5 is simply too big to fit the case size I prefer with the fittings of my choice....mATX/Quick-fit.

Innovatek was there before everyone else AFAIK.
