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.

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

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.

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 |

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? |

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 |

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

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

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

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 |

Plus the inlet and outlet are parallel, rather than perpendicular, when it comes to DDC.

I was wondering about laying a D4 on it's side, pump inlet still facing the rear of the case, pump outlet facing the waterblock inlet level with the waterblock with a short section of tubing running straight to the waterblock. with a bay reervoir in the bottom bay and an external radiator with it's middle about level with the pump. The pump would never have to raise the water more than a few inches. But really what I was wondering about and assuming was that there wouldn't be any additional stress on the bearing. I was also wondering if getting all the air out of the pump would be a problem.
Please excuse me if this all sounds a bit naive but I've found that the best way to learn something you don't know about is to ask questions. If your going to ask questions you might as well ask someone you think will have the right answers. I can't think of anyone better than the people here. edit sp |

That's what I did with CSP-750 MkII pumps for a while, but I've never tried it with Laing D4, and I can't do it with DDC due to its parallel fittings. CSP-750 isn't mag drive, though.

OK I understand about the no effect . What about the other two questions: bearing stress / air pocket
please bear with me guys I'm not an engineer |

if it is ok to mount the pump on its side, . . . . .
bleeding ? no idea, depends on the layout and your effort in bleeding with a connection pointing UP, a bubble can rise - otherwise you rotate the pump or case |

these were rhetorical questions I'll more than likely mount it conventionally but my mind likes to go over ideas from the sublime to the bizarre :-)
