whats a maul?

A 10 lbs two-hand sledge hammer, approximately 4´ long.

Hi, setting up my WC rig for the first time. can some pros clear my doubts.

which is better? UPW or DIW
any advise ?

what is UPW or DIW?
does it relate to Tap water for cooling?

:O and you fit that in your toilet tank!?!?!?!? 4 feet? That's like the size of a small child!!! It both scares and impresses me that, should you ever want to, you have the capacity to fit a small child in your toilet tank. Wow.

upw = ultrapure water
diw = distilled ionized water

just plain distilled water is best, with some anti corrosion additive like hyper lube.

how would useing heavy water effect cooling?

You wouldn't have to worry about the cooling between all the federal investigations and FBI agents following you.

Its only used for cooling nuclear reactors because of how it responds to radioactivity; its doubtful you'd see any improvement in cooling even with a test bench rivaling BillAs. Add that to what getting some would cost and what not...

fair enough

Nonono, I had it standing *next to* the toilet.
Don´t give me any stupid ideas ;)

you have a small child standing next to your toilet tank?
aren't you scared that he/she can take the sledge hammer out of the toilet tank and attack you when you doing your "business"?....
and then escape

;)

Back on topic...

I've contemplated building a cooling system that makes use of a water main. You'd have to be in a building where some amount of flow is guaranteed through the pipe 24/7. Build a heat exchanger that attaches around the water main with as much surface area as possible. wrapping 20 feet of copper tubing tightly around the pipe might work, but I'd try to design something where the exchanger is actually bathed in the incoming water somehow, thusly eliminating the resistance of the thick steel pipe.

kinda like drill a hole in the water main and snake the copper pipe all arround inside of the water main?

but what if you don't use the water for a few hours...
would the water in the main get warm.. diminishing the power of the water cooling?
unless you can garantee constant flow...

:D
Check Your mail, this is just too off topic.

Ewan, sorry for wrecking Your thread.

The OT toilet child was an improvement to the thread if you ask me. Kinda like the batman fins on US cars from the 50'S Completely useless, but they sure look good.

Krazy's idea of using a mains pipe as a heatsink isn't what I'm after, since there are all sorts of things you can use as a heatsink. You would still need a pump and a coil and whatnot.

Dude, you obviously aren't familiar with the physics associated with batman fins in relation to the aerodynamics of quad-wheeled motorized vehicular units. Much like racing stripes, tinted glass, or gold plated rims, well placed batman fins can easily boost your engine by anywhere from 10 to 20,000 horse power. That's why the space shuttle has those huge fins. Without the power provided by batman fins, the shuttle wouldn't be able to get into orbit.

on topic:

what you people really want is oil cooling. Grab a fat ass heatsink and shove it on the cpu, same for the video card, and everything else. Then just build a box out of aluminum(or better yet, big heatsinks). The sheer thermal capacity of the oil(make sure to use transformer oil for the pc, you can get away with motor oil for the other stuff)will cool the pc quite well, and the aluminum sides will dissapate the heat quite well. Dont go crazy and immerse the HDD and cdrom though.

If your gunna go the complete emersion route, you might as well go all out and use flourinert with liquid nitrogen
:D

What's the resistivitity range for the transformer oil you suggest?

What effect does it have on the PC board and components? What is the solubility of copper, aluminum, PCB, etc. in it?

What is its viscosity? Density? Dielectric constant? Vapor pressure? Toxicity? Flammability? Reactivity?

The stuff won't do any good if it eats away at the traces, the polymer substrate, or shorts out leads, or has a capacitative effect at other leads, or is too thick to be pumped or ensure some level of thermodynamic homogeneity, or evaporates too quickly to be used long-term, or turns the room into a toxic deathtrap or raging fireball.

Which would be cool, admittedly.

if you even considered that, a lot of people including myself would have to start bitching at you.
its not raining 10 months this year, and we dont have enough water even to put out massive forest fires in the interior. dont waste it on your cpu.

why? it doesn't effect you.

forest fires are a natural occurrence. Forest fires happened before we were here... just because the logging companies want the trees to cut down, it is a very big deal. It is unfortunate that homes get destroyed in the process. Would you tell me not to use a jack hammer for fear of earthquakes?

There is lots of water. Have any idea how much water the Fraser River dumps into the ocean on a daily basis? and that is one of many rivers.
get a grip Ambian!!!

I agree with madhacker, there is no such thing as "wasting water". If you "waste water" all that happens is it goes through the system and is recycled back into your pipes, or it gets poured out and seeps into the ground and into well or waters the local plants.

Also, how will using water from the pipes effect weather or not you have enough water to put out forest fires? He hasn't been doing it, and you don't have enough water as it is. If he starts doing it will you have less water? I don't think so.

By the way, where do u live ambian?
