Roscal does kits, hi and lo flow too
in French http://www.cooling-masters.com/news.php?id=75
in googlese http://translate.google.com/translat...language_tools would that all were so through, very nice job |

Ooooh, do I see some Swiftech bling? Me likes!

black is beautiful
me wants black block and silver (or black as #2 choice) hold down plates. |

yeah, MCW looks quite sexy in red/black
...a top-notch article for a quality kit. |

Wow! Despite the Googlese, that's the best WC article I've seen.

Interesting/curious. that MCR120 radiator's temperatures translate(according to BI Pros data ) heat dumps of ~ 47w and ~ 88w for a system-modeler's heat inputs of ~83w(75+8) and ~123w(115+8).
57% and 72% respectively. |

we gonna hijack another thread ?
where should we put this BI stuff ? |

It is your thread and Roscal is not averse to science.

no 'claim' to thread,
my only concern is that everything becomes so scrambled Les my whole problem with the modeling bit, is one to conclude that the measured watts are hugely low ? or temperature compression ? some of both ? - or that the model is disconnected ? why I test a disclaimer, conditions #1 all data is preliminary, the procedure is still being defined (Roscal note, those curves will be re-stated) #2 consider this rad data as a unique data set; in terms of control, accuracy and repeatability it is considerably better than the 2 previous efforts #3 rads connected in a uniform manner, laid flat, fan(s) pushing w/grille guard(s) #4 fan intake positioned 3" below the horizontal discharge of the environmental chamber's air conditioning #5 fan discharge isolated from intake with a 4" horizontal baffle at the rad discharge face (the rad body is exposed to the 'cool' intake air) readers interested in rad test data need to read and consider this post http://forums.procooling.com/vbb/showthread.php?t=11039 here is one so curious that I ran some addl points to confirm this curve will shift when I re-do, the tail will rise, but even so |

Black + red a likely combination for the future, or is the blue going to be kept (ie, black overseas models...)
edit - read about the 'designer' series

Has driven me to look(again) at flow-boiling ( "the bends", cavitation) Only got as far as : "For the dissolution of oxygen in water, O2(g) <--> O2(aq), the enthalpy change under standard conditions is (-11.7)-0 = -11.7 kJ/mole" O2(aq) possibly drops 0.83 mg/l per m(H2O) dP across radiator when no temperature change temperature.(Calculator) Looks a tortuous road, to retread after 45 years, to yield nothing . Looks more like pHaestus's territory. |

Looks clear that the higher flow doesn't let the water spend enough time in the rad. <ducks>

methinks you are illustrating my reservations re the connector dP being lumped into the rad's
much is experimental, the new setup has eliminated some of the tailoff - enough to consider all such part of an experimental issue ? no, not so confident as that a comprehensive set of the BI rads' performance will clarify some things, still unfolding as I am redoing 10 days of work (rad testing is such fun) |

Your "data presentation" includes the connector contribution.
So has be used or manipulated out. Quote:

wrt the rad dP, yes; often for both sizes
would prefer them out but the result is an abstraction we shall see |

Just considering Nitrogen(" the bends"component) would tempt me to change the dP correction from ~ 0.16(LPM x m(H2O)) to ~ 0.17(LPM x m(H2O)) Envisage water-vapour(cavitation component) to be larger. Oh woe. |

Maybe "Thermal Effectiveness" should be used to describe a radiators performance.
Is suggested inDecember's CoolingZone, by Zahed Sheikh, as "A Useful Measure of Cold Plate Performance". This measure includes both the "Heat Dissipated"(my Wa) and the important(to my mind) coolant's temperature drop across the radiator(my (Twi -Two)) |
