Tired of garbage XSPC pumps - what's the best, most reliable bay res/pump?

[computerpro3]

When I first got my XSPC watercooling gear, it worked great. That being said, the pump/bayres combo developed a very loud rattling noise within the first 24 hours. XSPC sent me a new one right away, and the second one was dead silent for about 12 hours. After that? Sure enough, at first a small grinding noise and now it's just as bad as the other one.

I never learn...cheap things always wind up being more expensive and I should just get the more expensive product first. Same thing happened with my Sabertooth...should have just went with the Maximus IV.

Anyway, what's the absolute best, most reliable bayres pump combo? Price doesn't matter. Silence does - I don't want some rattling, grinding peice of junk.

Right now I have a CPU only look but I will be adding 2 6950 blocks to it soon. I never plan on wcing ram and such.

Thanks in advance.

The bayres/pump combos are bound to be noisier than leaving your pump freely sitting on a pad of foam. If you're going to be spending money on replacement items, might as well go that route.

However, if you're going to be sticking to that combo, you could give a try to the Koolance RP-452X which would enable you to double your loops down the road, when/if you add those extra vga blocks.

Which pump?

This. I prefer my IWAKI personally, but the beast is a noisey little SOB so what I did was cut up an old mousepad into 4 squares and rubber mounted the pump on them, after that there was no more vibrations and shes been running fairly quiet since.

[Church]

Imho nice replacement for beasts like Iwaki would be new koolance's dual pump bayrestop with two D5 Strong pumps. Imho should be comparable in performance to iwaki, yet more silent.

[StAndrew]

The Swiftech MCP35X is always a good choice. For added cooling/life span, check this out:

http://www.xtremesystems.org/forums/...d.php?t=268560

And you can always go with the tried and true MCP655. Mine has been running for ~6 years now.

let us not forget the danger den monsoon if you have a d5 pump

I will probably retire my Iwaki to my test bench and buy one of the dual pump bayres from koolance to replace it ^_^ They look VERY clean and youre right, I bet its quite a bit quieter.

[ballzD33P]

which iwaki are you referring to? the rd-30? you feel 2x D5's are the same?

[ballzD33P]

/snip two D5 Strong pumps. /snip.

is their a new version of the d5 i am dont know about?

sry about the OT above... this is supposed to be about a d5/bay replacement thread....

[Church]

ballzD33P: Martin's review. Most powerful D5 (More head/flow even then for DDC-3.25), without built in speed controller, needs 24V for full power (at 12V somewhere between D5 and D5 Vario).

[NaeKuh]

well any dual d5's can beat an iwaki.

Your talking about 2 pumps vs. 1.

However i can bet you, that iwaki will last longer then BOTH of your D5's combined.


D5's arent invincible, ive had 1 fail, a friend of mine had 1 fail, and a few others i know have had them fail.
The D5 strongs are on 24V, but the heat dump recorded at the higher end isnt worth the pumping power.
Same can be said about an Iwaki RD-30 @ 20V+ .


If you ask me, nothing beats dual DDC-2. :X

But not many of us are on it... but reliability, id say the Iwaki would slaughter anything we've seen so far minus Ehiem.

Ehiem... The only company i trust more then Ehiem would probably be Taam, . more commonly known for there aquarium pumps labeled.. Rio.

http://www.riopump.net/

I wish Taam would take a jump into our hobby.
They would probably show us a kick ass pump which would make us go OMGWTFBBQ~!

Ie.. a smaller and better tuned polario series or Seio for our LC system..

DD moonsoon FTW great D5 with a great bay!

[Church]

NaeKuh: But imho those D5 will beat Iwaki noise wise. And serial configuration gives more redundancy, even if you say that iwaki-s in general are more reliable.

no doubt..

But we are talking about pumps themselves.
Im not a super big fan of the D5... I have that reputation here.

In a DDC Lover.. :P

i dont think so.

Have you heard the roar of a RD-30 @ 24V? lol...

Thanks for the link churchy, i was completely unaware that product existed.

With all due respect to martin and all the work he has contributed to this scene, I feel his rd-30 tests are flawed.

Notice how he has the inlet setup for the rd-30? That is the LEAST OPTIMAL way. For the inlet, he has "Master-kleer 7/16" ID x 5/8" OD" stretched over the 3/4" inlet of rd-30.

So, the 3/4" inlet of the pump is being supplied by a line that is 7/16" ID. See the problem there?

The rd-30 must be supplied with an adequate supply of water to really see it shine. Many people have bored out a tube rez and used that on the inlet (credit: ballz0r)

The fluid dynamics/mechanics going on before the inlet is quite a dramatic change based on available water input.

Also, I have never heard of an rd-30 dying, despite how bad it is being treated. Now, this could be due to the fact that its not very widely used in this application...

[bmaverick]

Have you looked at a DDC with an EK RES top?


Or how about two DDC with a performance top?

[Dazmode]

From our experience, statistically speaking D5 is the least trouble. Any not glued reservoir is good: DD, EK, Koolance.

[computerpro3]

Thanks guys, a lot to research and think about.

I absolutely need a bay res due to space constraints (I'm doing an old TJ03). With an E-atx board there's just no room left for pumps since I'm putting one 120mm rad in front and a 2 120mm up top.

What I'm thinking of doing is grabbing the RP-402X2 and a DDC. Now if I do this, will I need to buy a special top for the DDC? I assume the koolance res comes apart to install the DDC? I'd prefer to stick with one pump for now due to both noise and the fact that my loop just isn't restrictive enough to need two I think.

[penguins]

yes, the Koolance res is the 'Top'

FYI

Here is my old RD-30 test:


Here is Iwaki's published curves:
http://www.iwakiamerica.com/Literature/RD/RDCurves.pdf

My test / Iwaki's curve
Dynamic Pressure head in Feet of water

1GPM - 31.65ft / 30.8 ft
2GPM - 29.57ft / 28.2 ft
3GPM - 26.30ft / 24.8 ft
4GPM - 21.68ft / 18.4 ft

My results tested higher than Iwaki's own curve..?

That's probably just my uncalibrated manometer, but I don't think the smaller inlet matters in testing. Long term yes, if you hear cavitation in the RD, then a long term run like that can be bad....but if it's silent it's ok. I tested outlet-inlet so it accounts for any restriction on the inlet end.

It's all good..large inlet should help reduce restriction and minimize cavitation which can damage impellers long term, but I think the smaller inlet in that old test didn't affect the results any because I measured pressure differential which accounts for any of that. I think it was ok..

Cheers!

Lol I have to agree. even with mine being rubber mounted and all, my RD-20 (or RWD-20, I dont remember) was a beast.

But I couldnt hear it over my 4x 120 Deltas running at 15,000,000 RPMs (exageration, but they are def loud as hell)

My Super RD-30 E-Penis Edition : *i wonder who i got this from?*

Or how about two DDC with a performance top?

Love dual DDC's u cant get better then them, unless u go tri, and at tri, you get crap flow but insane head pressure.
I think i still am the only guy on the forum running these guys like this :P
