some questions for a bench of test of waterblocks (french inside) ^^

[LiCoolSolution]

Hello,

first, I am French and I must say that I do not speak English very well thus you do not panic if I ask you to reformulate such or such sentence.

I thus have some questions has to pose to you for a possible bench of test of waterblock. It is only one project, I thus get information for the moment.

First of all, which has to be the max head which this pump under good conditions should have ? 3,0 m approximately ? more ?

I also have some questions concerning your measuring units

has what corresponds this unit => GPH. Is this a unit of flow equivalent to L/hours ?

And what is your unit of pressure ?

Thanks for your answer.

PS : I am a beginner so do not criticize me too much lol :-p

GPH = gallon/hours
Gallon to Liter

Thank you Precarious for this answer

Pressure can be measured in lb/square inch, kPa, mm of mercury, bar, ATM, etc... not sure which is most frequently used for waterblock testing.

As to the max head of the pump, it depends on the pump. Checking the pump datasheet, and/or the manufacturer's website should give you the listed max head for your model of pump.

[LiCoolSolution]

the max head of my pomp is 2,9 m

It's a iwaki MD 40 (62lpm and 2,9 of max head) but I wanted to know if it were sufficient to make rather thorough tests (= good tests)

Is 2,9 max head sufficient and good ?

[OvcA]

SI unit for volume flow is m^3/s and Pa for pressure, while in watercooling l/h and bar are usualy used (non-metric units are quite awful and should phaseout as soon as possible).

[LiCoolSolution]

thx OvcA

And for the Iwaki ? Is max head good for testing waterblocks ?

Iwakis are nice since they can pump against quite a pressure. Probably the best "standard" (of resonable size, price and noise level) watercooling pumps around.

Bonjour!

3 metres, c'est relativement court, mais ca devrait te permettre de tester la plupart des blocs. Pour une analyse complete, tu devrais viser de tester tous les blocs au meme flo, soit 0.5, 1.0 1.5 et meme 2.0 gpm, si tu le peux. A ce point, tu aurais peut etre besoin d'une meilleure pompe, parce que certain blocs ont une resistance elevée Ã* 2.0 gpm

J'ai ouvert un site specifiquement pour les gens qui veulent ameliorer leurs methodes de tests (ci-bas, dans ma signature). Si ca t'interesse, tu est le bienvenue pour nous joindre!

[translation below, for the french impaired ]

Hi!

3 metres, that's a bit short, but it should allow you to test most blocks. For a complete test, you should aim to test every block at 0.5, 1.0, 1.5 and even 2.0 gpm, if you can. At that point though, you might need a bigger pump, because some blocks are very restrictive at 2.0 gpm.

I started a site specifically for people who want to get into testing (below in my sig): you're more than welcome to join!

[LiCoolSolution]

merci beaucoup bigben

Thanks

je vais faire un grand tour sur ton site lol

[OvcA]

When using G/H, which gallons are we talking about, US or imperial?

[bigben2k]

Eh, US. The one that's 3.76 liters (imperial is ~4.5 L).

[LiCoolSolution]

1L = 0.264 Gallon non ?

[LiCoolSolution]

bigben, tu es français ?
euh j'ai vu ton site mais il n'y a pas grand chose apparement....
A moins que je me soit trompé....

[LiCoolSolution]

with the fact, which does want to say PSI ?

au fait, que veut dire PSI ?

[Roscal]

Google bourdel

C'est mal barré monsieur Therin LOL

BB2K parle un peu francais mais l'est pas francais

Yes.

PSI - Pound per Square Inch
It's an unit for pressure, albeit a weird one since it conseals the fact that pressure is force per surface unit.

[LiCoolSolution]

rosco => ba apparement la pompe c'est pas mal mais pas assez pour la hauteur d'eau.... Je suis un peu dégoutté lol

En plus l'anglais et moi ça fait 2 lol

Google j'ai fait des recherches et j'ai trouvé pas mal de trucs sur procooling justement

ici également : http://www.leesspace.com/Testing.htm
et lÃ* : http://thermal-management-testing.com/

Ainsi que d'autres sur overclockeurs.com etc... mais je m'apperçoit que c'est assez difficile quand même mais c'est pas grave, ça me donne encore plus l'envie ^^

[LiCoolSolution]

je pense que 3.5-4.0 m de hauteur d'eau maximale est un minimum pour tester des waterblocks

I think that 3.5-4.0 m of max head is a minimum for testing wb

[bigben2k]

Non Roscal, je suis effectivement francais, a moins que tu as quelque chose contre le Canada? :P Canadien-francais, l'anglais c'est ma deuxième langue...

LiCoolSolution, une option: deux pompes...

Aussi, j'ai personellement choisi d'utiliser une pompe DC (au lieu de AC) pour la capacite d'ajuster le flo par voltage, et non pas par valves.

As-tu visité la section "Forum"? ( forums.wbta.us ). C'est seulement ouvert depuis Octobre, et de toute facon, c'est mieux quand c'est tranquille!

[LiCoolSolution]

effectivement j'ai regardé un peu le forum mais bon, il n'y a pas grand chose en français lol

c'est normal me diras tu

Pour l'option de 2 pompes ça n'augmentera pas la hauteur d'eau.... enfin je pense pas

Juste le débit non ?

[bigben2k]

Non, tout au contraire. Arrange deux pompes en serie, et tu auras plus de pression (meme debit). Arrange les pompes en parallèlle, et tu auras plus de debit (meme pression).

[Roscal]

Tu parles un peu bizarre pour un francais/canadien je trouve

[LiCoolSolution]

moi je trouve pas

[bigben2k]

he he...
