Totally off the subject...

I noticed you linked to hyperphysics. I have been going to that site for years now. It is the total shiznit for physics on the web. Nothing else even comes close. I get lost in there for hours reading it. Sorry for the off subject banter, but I had to give that site its props. We now return to the show in progress... |

I believe that someone tried running a LRWW block backwards, but I don't remember if it was a White Water or a Cascade. The result was a bump in CPU temp in the order of 10 to 15 deg C, as I recall.

Someone sold a Cascade second hand to a guy where the guy who sold it had installed the middle jet plate in up-side down. I have no idea as to why it did not leak as there was no O-ring seal between the middle and copper plates now, and the inlet of the block was basically washing over the ends of the jet tubes and moving straight on to the outlet, and almost never ever coming into contact with the copper except for on the small circular section off to one size where the middle plate outlet was located against the copper plate. Some water through the momentum on the inlet must've been forced down the tubes into the cups, and the pressure imbalance would've had a very small amount of water flowing over the tops of the cups and up and out of the other jet tubes that weren't directly under the inlet. Indeed, this guy was reporting something like a 15C difference after flipping the middle plate back the correct way. I remember now that I was utterly amazed that it even worked at all without frying his CPU. I remember this guy's story now because the middle plate had cracked as a result of the misinstallation and we arranged to replace it, which was a "blue moon" request. |

I knew I wasn't crazy!
I don't get why anyone would be interested in running it backwards: it's just not meant to run that way. Oh well... |

I can't belive someone put the middle plate in upside down. I can't even picture it in my head how it would even go together without it being so freaking obvious it is not the right way to do it. My guess is the guy took it apart, dropped it, stepped on it, and is playing stupid to get a new middle plate free.

Hi!
Can anyone tell me the reason for the discoloration of the copper seen in the MCW6000? |

The discoloration is from heat induced oxidation -- ya need the copper mighty toasty to braze it. It doesn't appreciably alter performance, but if you don't like it in there, a rinse with caustic soda (sodium hydroxide) will clean it off.

Thanks Groth! That´s just what I thought!
I´m having a discussion in a wc forum in Portugal about the said discoloration of the block. Some people were saying that it was created because of the variation of temperature in the waterflow and that it formed some kind of pattern showing the heat spreading from the center of the block lol! I knew it was some side effect of the brazing/casting of the block, just needed some backup from the pros. I´ll leave the link for the thread, for all of you Portuguese speaking people. (nice EUvsUSA flow threads) |

@Silent Bob (you know, the bot might resent you).
Oh yes. Another "lets throw ludicrous concepts that defy common sense and laws of physics, thermodynamics, etc etc" thread. Clearly informed people. (Acho piada o Atomez, teve um kit da thermaltake é torna-se um "expert". Fantástico.)

The discolouration is interesting. I wouldent of thought it gets hot enough to do that
Edit: lol i see we have had this discussion allredy. I should read the whole thread befor posting Last edited by SlaterSpeed; 06-03-2004 at 02:00 PM. |

pH, can you tell us what type of metal that divider around the inlet is made of? I have one of these and wanted to know if it's copper or not... Thanks.

not copper. Stainless steel I "think"

Well, a quick googleing tells me that copper and stainless steel has anodic index diff of 0.15 - 0.25. I ran 100% distilled for about a week... Should I worry about corrosion inside my block?
BillA, why didn't you just use copper divider? |

may not be stainless? I assume he'll pop in here eventually or else e-mail swiftech support

cu too soft
the ss in contact with the cu should present no problems - do you know of any ? EDIT: some addl info http://www.marfas.com/corrosion.shtml for corrosion to be apparent the ratio of ss to cu must be high, this is the opposite of the MCW6000 case where the ss surface area is quite small as compared to the cu Last edited by BillA; 08-10-2004 at 12:20 PM. |

Good stuff. Thanks.
BTW, those were some quick responses... Do you guys stay away from this place at all? |
