It surreal to need Babelfish on ProCooling. I like what it does to Ben's sig. :)

Personally, I would say 5 m of head minimum. That gives you extra pressure to be used for flowmeter, pressure sensors, and thermometers. It is better to have a too powerful pump.

For units, I suggest working in L/minute and mH2O (meters of water). Both are common in waterblock reveiws, both are a good size, both are easy for people to visualize.

What website will publish your waterblock testing?

si vous avez une MD40, elle est plus fort que ca - 2,9M est une MD-30RX...
une MD-40R est 4.6M max head et 45lpm, une MD-40RX est 3,3M max head et 75lpm.

les iwaki avec "x" ne sont pas ideale pour nous, parce qu'ils sont pour l'haut flux

(i hope this makes sense, i haven't written anything in french for over 20 years...)

It is 2,9 max head at 50hz. Damage for me if at least 5m is needed ...

Thx Groth for your answer ;)

It is for a french web site but it is not either for immediately

Which pump advise me then ? (an iwaki)

With what does correspond the L on some of the pumps iwaki ? for exemple MD-15RLT Iwaki Pump or MD-70RLT Iwaki Pump

Thank you very much =)

weird - it has the same performance as a 30rx, but uses slightly more power.... it also doesn't seem to mention iwaki on the label which seems odd ...

"L" indicates it's a 115V pump (bad news for us europeans therefore...)
"T" indicates threaded connections on the inlet and outlet

50 Hz users suffer a performance hit, over 60 Hz users... sucks to be french! ;)

it is hard to live in France sometimes :D

Damage for you, yea! lol - "too bad for you" is better i think ;)
désolé, mais c'était plus fort que moi!
domage pour toi, car tu auras Ã* acheter une nouvelle pompe, quoique je doute fort de l'utilité d'effectuer des tests de wbs Ã* plus de 1.5gpm, la plupart des gens ont beaucoup moins que ça avec leur "setup", plus aux environs de 1.0gpm. Mais comme BigBen l'a dit, une pompe DC est peut-être préférable compte tenue de la facilité avec laquelle on peut faire varier leur débit...

Oui. L'utilité de tester Ã* 0.5, 1.0 et 1.5 gpm te donnerais trois point, pour établir la courbe de resistance-débit du bloc. Un quatrième point aiderait pour confirmer la courbe, parce que tu auras besoin de trois points pour determiner la courbe. Mais tu as toujours 0,0 come point de reference...

[tsl] Yes. The usefulness of testing at 0.5, 1.0 and 1.5 gpm would give you three points with which to establish the flow resistance curve. A fourth point would help in confirming it, because you'll always need three points to figure out the curve. Then again, you always have 0@0...
