Haha! Altering a pump for bling is stupid and asking for trouble IMO, I know we share that thought. If the bling DCC was $20 cheaper, I'd still buy the non blingafide version. However, if it were Laing who made and offered a different top, that would be a different story.

BillA 12-17-2004 12:20 PM

"blingafide"
good, good

flatline 12-17-2004 12:40 PM

if lang offerd a new top with 1/2 barbs (with or without bling/lights/buzzers/flags)
id have 1 in a second

BillA 12-17-2004 12:55 PM

and I imagine you would have company
all making an uninformed choice, bigger barbs do not equate to more flow - just bigger barbs

your 1/2" is the bling, most likely nothing you are doing requires the use of 1/2" tubing
and most certainly the DDC is foolish for a 1/2" system

Yes but certainly easier to just plug and play a DCC with 1/2" barbs IF the system is already equiped with 1/2" tubing and blocks no? In that case, if no 1/2" is to be offered just use some 1/2" to 3/8" reducers. I do think if a 1/2" version were available, it would outsell the 3/8" version.

BillA 12-17-2004 01:19 PM

and again I agree, but it would be selling for the wrong reason(s)

if the 1/2" system was actually a low flow resistance one, then the bigger Laing pump will deliver better performance

flatline 12-17-2004 01:25 PM

yup i have a 1/2 system and dont want to use redusers or mess about with tubeing over tubeing i wud like the ddc as its a 12v pump thus not needing switches or relays to oparate and i feel may actualy be better then my presant Eheim 1048 also in the french reveaw of ddc there was a statement about restriction of inlet so maybe there may be a little flow to be gained useing 1/2 barbs after all

"most certainly the DDC is foolish for a 1/2" system"
i dont feel that is true :dome:

(edit and hopefully the ddc dont leak like the d4)

BillA 12-17-2004 01:35 PM

"(edit and hopefully the ddc dont leak like the d4)"

a leaking D4 ??
details ?
who contacted ?

yes, I am interested

flatline 12-17-2004 01:45 PM

was on some uk forum il try and find it again but im more interested bout ddc's in 1/2 has Laing ever tested this? :shrug:

Of course it is for the wrong reasons, isn't that called human nature? :dome: Shit, we eat cheeseburgers for the wrong reasons. Yes the 650 would deliver better performance, but again, some people don't care. IMO it would be a worthy option.

BillA 12-17-2004 01:59 PM

yes, the same pump 'design' with 1/2" barbs is called the D4 by Laing, MCP650 by Swiftech

ns1
for space and/or noise, sure - just not performance (then why the 1/2" ?, lol)

Niatross 12-17-2004 04:36 PM

I'm so confused :-(. What should i do??? ok here was my plan. A MCW6002 , one of those new poly whatever bay reservoirs, a 7 3/4 "X 6" shrouded heater core with 2 120mm X 38mm fans in a push /pull setup, 1/2 " fittings all around. What pump should I use? Someone please save me before I screw up and buy the wrong one ;-)

Looks like you're gearing up for performance and are willing to tolerate some noise (maybe 120mm Panaflo M1A fan levels?). If that's the case then I would suggest switching to a one pass 10x6 heatercore with 2 120mm fans on one side, using the MCP650, and leaving it at that. If you are putting this system together as a "low noise" unit then I'd go with a Black Ice Pro2 and 2 Papst fans instead of the heatercores, would use a MCW6000 wb, use 3/8"ID quick disconnects all around, and then go with the MCP350. That's my personal opinion; no hard data atm

Niatross 12-17-2004 04:53 PM

I was reading over at overclockers that fans in a push/ pull config produced significantly more airflow. Especially in a thick heater core (2") situation. Yes I am willing to tolerate more noise when I'm in a gaming mode. I use a reobus when in 2D
I'm using a MCW5000 at the moment with the Swifttech one pass radiator . I was using the old swiftech 300 pump before it crapped out on me and am now stuck with a garden type submersible at the moment. I'm really not happy with the rise in temps under load

pHaestus 12-17-2004 04:56 PM

The performance vs. noise tradeoffs are not worth it. You'll get lower temps and significantly less noise with a radiator with a larger facial area.

Niatross 12-17-2004 05:10 PM

noise is really not my concern. I'm already using the fans I talked about on my present setup. I'll slow the fans and overclock down when I feel the need for less noise. We're only talking about 2 1/4 " difference between a 10 X 6 and a 7 3/4 X 6, mostly split at the top and bottom, I can't believe the difference would be too great. Plus more importantly I already have the heater core ;-) . Still my basic question was with the system I envision what would be the correct pump

JWFokker 12-17-2004 07:37 PM

The difference between 5V and 12V with my two 120mm Sanyo Denki fans on a 3/4" thick transmission cooler is about 1-2C at most and at least 6dba. I'm running a 3100+ Sempron overclocked from 1.8Ghz to 2.5Ghz at 1.85Vcore. At 12V they push 102cfm each, at a significantly higher static pressure, but temperatures remain nearly unchanged so I run 'em at 5V 24/7. Very quiet. On the other hand, if you use a thicker radiator like a heater core, you might see a greater benefit from running them at higher rpm due to the increased static pressure allowing use to make use of the additional thickness of the heatercore compared to the transmission cooler I use. I hope that made sense. There's no benefit for me to turn up my fans, but because you have a thicker radiator, it may be worth it, though it'd be quieter and more effective to just buy a second heatercore, run it in parallel and strap a couple more fans on it.

Tamale 12-17-2004 07:56 PM

i just thought i should throw out that i'm gonna use the DDC in my 1/2" system.. mainly because i plan on having at least two blocks and that big-ass 120.3 radiator..

we'll see how it does with the 3/8" to 1/2" converters :)

flatline 12-17-2004 09:34 PM

report back pls Tamale + what u useing now?

also consider the 1/2 tubeing over 3/8 with clips as sugested by Cathar

meltedbarrel 12-20-2004 01:04 PM

Hi everyone. Just found out about you.

Question: Can this pump be mounted vertically, like up against a wall, or does it have to be mounted horizontally, i.e. bottom of a case?

BillA 12-20-2004 01:14 PM

any position
can't figure out why the site does not say that ? hmmm
will correct

meltedbarrel 12-20-2004 01:16 PM

thanks for the quick reply unregistered. That is great news for me.

It works fine vertically; that's how I use mine.

Not exactly, position with rotor upside down is bad. There's noise produced because rotor is falling down to the volute (magnetic field isn't too strong to keep it when it spins). I'll notice this when I tried them and Laing don't recommend it too in their pump notice :dome: . Vertically mounting isn't a problem at all.

BillA 12-20-2004 02:50 PM

Laing has stated that the pump may be mounted in any position,
this has been considered by all parties and is a statement of fact

the only real concern is the ability to purge the impeller of air,
note that if a bubble is left 'in' the impeller the pump can burn the graphite bearing in seconds

I've had several running inverted for 4 mos now with no discernible effect

Niatross 12-20-2004 08:53 PM

I assume you guys are talking about thr DDC here. But what about the D4/650? could it be laid on it's sideon a bracket with the output nipple level with the waterblock intake? A guy could darn near eliminate head loss. Though I don't imagine head loss is very great with a normal layout either

BillA 12-21-2004 09:15 AM

no effect on head loss/output due to pump position - other than due to the tubing
- practical statement, not absolute

pHaestus 12-21-2004 10:15 AM

In other pumps people have noticed a decrease in noise when orienting them like this (inlet facing up and outlet parallel with ground).

BillA 12-21-2004 10:27 AM

that's the bearing rumble in the aluminum bodied MCP600, et all
no relation to the design of the Laing pumps which have a single contact point with the (single) rotating part
