Laing DDC3.25 // Koolance PMP400

[Sparky]

he has something better with more restriction.

Its called a Koolance - 350

o rly? I didn't know that the 350 had taken the restriction crown.

[Boogerlad]

dude it wouldnt be the first time you made people go out and buy stuff.

Oh btw martin your correct about the Primochill LRT tubing having the best bend radius. I compared it to like 4 different brands.

so primochill lrt over feser stuff?

[Martinm210]

He he...you know I'm just poking fun. But you were the first one I thought of when I saw the results you Democrat you.

andyc

Yeah I know... I'm independent, but I thought it was fitting since I've heard other people tell me just that when I was mulling over some buying decisions...

Wish I could take the credit, but that was Virtualrains tubing review that I was going off of. I do think I'm going to buy some of the primochill black and give it a try. If nothing else because they carry my favorite 7/16" ID x 5/8" OD in UV colors. After going distilled water/UV tubing, I don't want to even think about dyes ever again.

[skinnee]

Interesting results...only 2.0GPM, thats surprising as well.

Thanks for taking the time to test and sharing the results.

[SNiiPE_DoGG]

I've been preaching Primochill PRO LRT since I recieved my lengths in november.... Not only does it have the best bend radius but it also has super high durometer (much higher than tygon)

[Hondacity]

yeah the lrt pro is uber good...but have you tried the clearflex? it kinks..but heck i love it...oh well

skinnee ...two gpm...because i got the vl3s...they're restrictive. pls overclock the i7 to 4ghz

[skinnee]

vl3's...the vl4's are the latest revision or am I getting the numbers screwed up?

[Hondacity]

vl4's are the latest and greatest....

vl3's are what i have

[shazza]

Thanks, again - Hondacity.

(After visiting three of your flow threads, I think I've finally figured out what the pics mean ). Maybe a footnote for dummies on how to read the results?

Isn't the bend radius directly attributable to the high durometer? I thought the higher the durometer, the tighter the bend radius and the more torsion it puts on the blocks.

[Serpentarius]

laing kept improving DCC3.1~3.25 .. how come it never plan any for D5?

Well by durometer (at least as I understand it) I mean the "hardness" of the tubing when you press on it (the best way I can describe it)

theres a D5 Strong. :P

Suposed to be almost on par with a RD-30.

Good question! They would be the perfect players interested in making a better impeller for the D5. I know we like the compactness of the DDC, but a redesigned D5 with better heat dissipation out the motor casing and a much improved pressure oriented impeller design, and we'd have something pretty neat.

They are probably just tayloring efforts on what sells the most, which I suspect the DDCs outsell the D5s several times over.

Thanks for the testing Hondacity great work!

oh gowd martin u know about the D5 Strong.
And you know how crazy i almost went on trying to get one. :P

Sound slike an awesome pump for a solar hot water heating

[generics_user]

this is disappointing...

[situman]

The question is, how reliable are these things. Wonder what's Koolance's return rate on these.

To quote an e-mail that I sent to Gary last year:

As for the D5 Strong, if it was worth it, then I would have brought it in a year ago. When run at 12V with the 810N housing, the D5 Strong doesn't provide much of any improvement over the standard D5 Vario. Yes, the maximum head pressure is a little higher, but if you look at the pump's PQ curve, you'll see that the boost is almost entirely before the 1GPM mark. If the entire PQ curve had been tweaked to be more robust (like the DDC's) and they bumped the head pressure, then you'd see some real gains... and running the pump at 24V in a water cooling system is absurd (sure, you gain about 4' of max head pressure over the standard Vario and push max flow out to around 6GPM but the pump's wide-open power consumption jumps from 24W to around 50W). The D5 Strong is not a particularly ideal pump for water cooling.

:P yeah i know...

which is why i got the RD-30 instead.

I would like to point out that another difference between the two pumps, is that the 3.25 operated 8-13.2vdc and the 3.2 operated 7-12vdc. I'm sure if both pumps were run at their maximum voltages we would see a much larger difference.

whoa.. that needs to be tested... NOW

[faster3200]

the 3.25 operated 8-13.2vdc and the 3.2 operated 7-12vdc.

Fixed.

I agree this should be tested, but how many people are actually going to run them at higher than 12v on something other than a normal psu?

[evil-98]

mcoffey thats a lovely setup

and previously thought dean said 23 dcv.. i assume 13.2 wont do much
