Okay i may have my hands on a brand new Iwaki RD30. Been told that 18V is the sweet spot to run these at.
My loop for it is only a CPU, X6800 (awaiting RMA replacment as mine has died!)
Rad will be a top mounted Thermochill PA120.3.
NOTHING ELES IN THE LOOP, CPU ONLY.
What block would you advise?
There is going to be stupidly high presure and flow here!
RD30 users please post any info you have etc
Pete
Darn... the Storm is still the best cpu block there is for the X6800, unless you can requisition a Silver G5... and all the talk about the Storm being restrictive would be moot.
Remember something guys, the RD-30 at 18v will give you about a 7M head, maybe a tad less. It is not as powerful as it USED to be given the fact that the 18w DDC with a proper top has a 6.5M head. 2 of them (18w DDC's) are far more powerful than an RD-30 at 24v.

Hahaha Iwaki has a pump model that begins with the model designation "WMD" I want that lol
Yeah that is the 'American' motor version of the 'MD'. The MD is a far better choice over the WMD. The MD is smaller, quieter and cooler running than the WMD and is Japanese made.Hahaha Iwaki has a pump model that begins with the model designation "WMD" I want that lol

Hi,
Where did you buy RD30 as I cannot find any Iwaki pumps in UK
Thanks.
My setup
Xeon 3060 @ 3.4 (24/7) VCore 1.375, FSB Voltage 1.275, MCH Voltage 1.525
Cellshock DDR1000 @ 4-4-4-12, DDR900, 2.16V
Intel BX2 / Swiftech Storm / 7900 GT SLI with EK blocks
Thanks.. it was just a joke. You know of an Iwaki retailer in the US? No intentions of buying.. just to compare prices.
Also, Nikhsub, I know you are an advocate of using dual DDC+s w/ Petra. Do you know whether using dual DDC+ with the Alphacool dual pump adapter is a lot worse?

Ooo Thanks.
Oh here we go... WP-IKMD70RLZT.. Enough to spray water into my neighbor's house .. max head 66.6 feet, max pressure 42.7 psi, max flow 11.4 gallons per minute ... we sure this is enough for my Storm block lol

YOu mean the single top for 2 pumps? I think it should work a treat. Not quite as good as 2 pumps in proper series, but certainly exceptional.

The thing is that me and my crazy ideas.. I how have two loops and I'm going to three loops. I simply don't have space for five or six pumps inside that poor case lol (also MM but Opti-1203 style with dual PAs in front). Right now, I have four DDC+s and two D5s at home, unmodified. I was thinking of going to three pairs of those DDC+/Alphacool contraptions. I still have no idea how I'm going to mount all that crap, but I guess I'll cross that bridge when I get there lol And I may finally have to submit myself to 7/16" tubing because all that tubing is getting kind of obnoxious lol

Yeah, I got my Iwaki at customaquatic. They didn't have the RD30 in so I went with the MD-20RZ.

Sorry for the ridiculously stupid question. The MD-20RZ has no problems just running off 12v computer power ?
MD's are AC pumps

Yeah, the MD's run on AC power but I installed a relay so that it turns on/off w/ the power switch on the front panel.

After the ddc was released, I never saw the point of have large, AC powered pumps in our small water loops.
I'm running a restrictive block (Storm) plus will be running two GPU blocks soon, a 360 rad, and lots of 1/2" tubing since this is a big case. I was wanting the best single pump solution possible for the job, and when I couldn't find the RD30 at a reasonable price, I went with this one as suggested by all the pros here.

Iwakis don't break. Plus, you can get around the AC part by relaying it to your computer's PSU (a nice relay switch with r/f filter can be purchased at sidewinder for ~$28). Also, you can sometimes get a used Iwaki for a similar price to a DDC-2/Petra's. I just got an MD-20RZT for less than that price. Since Iwakis are so durable, the fact that they are used doesn't really make much of a difference. They are aquarium pumps, so if they fail, the expensive fishies could die. That is why they are designed not to.
Mr. Peanut--have you noticed the impeller end of your MD getting hot? I've been wondering if I should put a fan on it because it gets kinda hot w/ the side panel on my case. I know all pumps probably do, but I want my pump to last a good, long while.

I would agree that the Storm is the best way to go.
However, that pump will only hinder your cooling. Get a DDC1. I believe that will give you the best temps.
Stick with the Iwaki. You'll regret DDC, especially when this happens to it.
There are probably 10 cases or more that have happened on this forum alone, of DDC's failing. Feel free to take the risk. That, and nobody has tested the DDC under load of a loop. What if it turns out it sucks in a restrictive loop?

Iwaki has bragging rights, but DDC-2/Petra has Petra-loving rights. Take your pick.
Probably because of all those Petra tops everyone seem to be using.
And doubling up on pumps...that's just pointless.
