There's no version 2 in fact, they only added external fix on the body as a little improvement.
I don't know what the matter with graph but their 570L/h are impossible to achieve @12V with my test, for sure ! I mailed Ralf from Laing to know exactly the conditions of their test because, as usual, a lot of data are missing (voltage?). Here's his first mail to my question about these strange 570 L/h today : Quote:
Bill I'm waiting your test, it take a couple of minutes to confirm or not. |

no, "lovable" is not an adjective normally associated with me (that's your thing)
my fuse is pico-seconds when compared to other vendors Roscal Oliver is aware of the graph and it is being pulled - period so the quotation seems strange to say the least would test but the bench is tied up with rads and the second not yet assembled more than a bit overloaded here |

Some kind of answer was needed. You took the kind of (re-)action Swiftech consumers, WC community and resellers nedded. As you surely realise, this market (WC) and in particular WC pumps doesn't have a lot of good references to sustain its credibility. So, one couldn't afford to loose this one. Nevertheless, Laing's move wasn't a smart one («all disclaim knowledge of how this happened (to me)»). get stuffed |

Some news about the 570L/h mystery.
Mail from Laing : Quote:
Thoughts? |

strange indeed
Laing has a test loop in San Diego which I should go visit, will try next week the data posted, given to us by Laing, was also confirmed in SD; so whatever the procedure is - both facilities are using the same setups the techs may think they have a 'better' method, but they failed to convince Oliver it seems 2 DDC in parallel = 1 D4 (at half the cost) ??? and believe it or not, we are already getting inquires about running 2 in parallel BTSOOM |

More explanation from Laing :
Quote:
If the V2 curve was *true*, I should to find a flowrate higher of ~40 L/h in my low restrictive system (using PD on WB) but it's not the case :shrug: . Anyway, the little difference is not really important because pump is really silent and powerful, some L/h more or less is irrevelant. |

interesting, and the initial rational re 270L seems even more peculiar - the difference at that point is considerable between the 2 curves

1> Sounds crazy to measure one pump using two - Thinking - No, makes some sense as pump mfg has to provide method to client engineers to replicate data transparent to individual bench setup (fittings, tube friction, etc.) 2> Implies an absence of a valid engineering standard for replicatable flow measurement? What is the equivalent to IEEE for pump engineers? Is there not an international standard for this type of measurement? |

Hi,
Do you know any store in the US who sold the mcp350 alone, i only find it include in H2O pack. i tried on swiftech store, but i ask for avaibility before. and here the answer from them : Quote:

And they got mine shipped out ASAP. Ordered Tuesday and got it today. I talked first with Swiftech, but Michelle said they wouldn't ship until next week. I think Swiftech needs a BillA for sales.

Thanks for the info,
Anyway i would prefere the swiftech for the attach system (i am a lazy ass ) so i don't have to do it myself. i keep lokking, and let you know. |

Predicted temp difference between CPU and ambient, the lower the better:
Yes, it would seem the DDC can outperform the D4 in a restrictive circuit as it dumps less heat, which makes up for the slightly lower flow rate. In a less restrictive loop, the amount of heat 'saved' may not be enough to overcome the gains due to increased flow with the D4. ATM, I think the decision is more likely to be influenced by your noise tolerance levels |

DDC temperature wise.
But would like to see cathar coment at what pump to choose, "overclocking wise".

Hi how does the Laing DDC/MCP350 compare performance wise to dual csystems in series, thing is iv ordered a pair of these and after reading a few horror stories am a little worried, a 1250 is easy to get hold of and was happy with the last 1250 i owned, the MCP350 would have to be an import due to me being in the UK
im stuck on what pump to choose, the loop will include swiffy 6002 silverprop HL 120.3 fillport from a tline What do you guys reccomend, am i better off importing the MCP350 or going for a good ole reliable 1250 like i had before |

iv been offered a nearly new aquaextreme 50 (mc 600) for £60inc, basically same price as 2 cp750's and not sure what i should do
the mcp350 looks nice but unsure it will be enough for my rig |

60 pounds? thats a bit steep isnt it?
I got mine s/h (used once, so yes, basically new too) for 75nzd, which is basically 25 pounds...

given the low $ i suspect you'd be better off getting a 350 from sidewinder at $79.95 (they ship USPS, so it'lll be pretty cheap - it's not a heavy pump..) |

Should be slightly better than the 350 i hope tho im sure a tad noisier compared to my 1250 i had before shame about the price, im not sure i can be bothered to have 2 larger eheims in the case with the extra tubing etc tho im sure the pc75 will have the room If the pump is no good im told it has 2 years warranty anyway so should be fine at elast for 2 years |
