That's it.

An exercise for the student: Read the stickie post above, and find out whether to get the with or without AC version.

More news, as it develops.

Check reviews and owner experiences. Your mileage may vary.
I'm sorry to put down the system you have confidence with, but a good friend of mine has had a "Big Water" for several months, mysteriously developed a leak at the cpu waterblock and dripped over a pair of BFG 7800 GTS's (destroying both!).
Of course he wasn't very charmed, nor will he ever endorse the "Big Water" kit EVER!!!!!!!!!!!!!!!!
Just keep an eye on it. gL

Guys, guys, please be aware of that Dani is about 11 years old. Actually I showed him a working water cooling system, and told him to go and seek for details himself. So perhaps he doesn't get your whole point of explanation, don't be surprised just know who you are talking to

Ok, that's understandable...we were all there at one point. It's nice to see a youngster interested in something like watercooling.

Fair enough--thanks for the info. Better than the typical "my system rocks, yours sucks".

Can you tell me where the leak was? tube-to-barb? barb-to-block? lucite-top-to-copper-base? That would give me an idea what to check.

Gracias

Hey Dani,

I was Googling around, and found this article on watercooling:

http://wiki.extremeoverclocking.com/wiki/Watercooling

It looks like a good description, with photos of the Bonneville heatercore, etc.

I hope it helps!

Stay cool.

My question is do all the parts of a water cooling system need to have the same inner diameter?

For example: If I bought a 1/2" Maze4 GPU block, an Apogee CPU block with 1/2" fittings but then connected it to a 3/8" fittings pump like the MCP350...wouldn't I be defeating the purpose of having the greater flow of the 1/2" system?

Thanks for any help you can provide.

Yes, and no.

Yes, in that obviously a narrower section of a given length will increase backpressure and reduce flow in comparison with a larger diameter tube of the same length.

No, in that it's a common misconception that having one 3/8" (for example) constriction in a 1/2" system will reduce the flow to the same as an entirely 3/8" system. In reality, flow resistance if a function of diameter times distance, so a short 3/8" ID system could have greater flow than a long 1/2" ID system.

So yeah, the fatter the better for flow, and if you can avoid constrictions, do. But constrictions don't remove all the advantages of larger diameter sections, and shorter lengths reduce flow resistance.

Make sense?

I'll need to chew on the diameter X distance thing for a bit but overall; I get the idea that most of the time fatter tubing is better than skinnier unless the total tubage is going to be very short.

And please, correct me if I got it wrong!
