Water Cooling?

[mobrien_12]

if you get say a Copper CPU block, you will have to get a copper radiator, copper GPU blocks,etc..If there is any other metal besides copper, major corrosion will occur.

That's a good point.  With different metals, the cooling system will essentially become a (VERY) weak battery.  Not enough to cause electrical damage, but by causing ions to migrate from one metal block to another you will get corrosion.  I would not have thought of that.

Ok, I was totally ignorant about it, what I was thinking of wasn't water cooling, but gas compression with some other substance. But not freon, I don't think. I know some rich bastard who wastes money on silly crap and he has one of these. Has a huge plasma screen too. I looked into it, it's not water cooling. So if you really want nice cooling there you go. But just to quiet things down, anything but air fans is not worth it. This super cooling is only worth it when overclocking way too much.

With water cooling do you hear anything or can you hear the water being pumped or something?

Actually to be specific, you don't need to match all the metal.... you could have a copper cpu block and a radiator with copper tubing and aluminum fins.

some of the watercoolers I've seen recently on the net still have a fan to cool the water unless you have a chiller.

I repeat! All water cooling needs to be air cooled, to cool a a fully loaded high end system you will need a radiator that needs 3 roughly 50CFM 120MM Fans, unless you have some massive radiator...Phase Change cooling is that expensive if you do it yourself....can be done for about  $400-600 by your self, high end water cooling costs about that much to...A chiller also uses phase change, hell if you wanted really getto phase change, just take a water block, and stick an upside down air duster with the button pressed down....The air dusters use refriderants..

Why don't we just build our machines into a fridge? :p

That would be nice, if it worked.

I was thinking of that too, but physics-wise refrigerators are quite in-efficient, your computer would overheat in no time, sadly

Thats why you stick it in the freezer, the freezer recycles cold air.

Another thing, some of the newer AMD Opteron and FX CPUs have a really bad cold bug( a cold bug is where below a certain temperature, a CPU just wont start anymore), sometimes the cold bug can be as high as 15*C, but most of the time its around -40*C

Actually, putting your PC in a normal freezer, or a refrigerator, is a BAD idea.  

Water will condense onto the circuits.

Some company makes a special case that is essentially a freezer with a dehumidifier in it so you don't have this problem.  I don't remember the name.  You could get unbelievable overclocking out of it... many years ago AMD had allowed you to overclock an Athlon to rougthly twice it's speed without violating the warranty, but only if you used this case.

I don't remember the price tag... but it struck me as insanely expensive.

Thats why OCers use insulation with -60*C Phase Change coolers, although, the record was an FX-60 @ 4Ghz , its stock is 2.6, Most AMD dont make a 100% OC, altough the average P4 under extreme cooling usually can hit around 6-7Ghz

My experience  with watercooling.

It is simple to setup, easy to maintain, extremely quiet and entirely dependent on one little pump that will give you grief to no end.

The new 64b processors actually run a lot cooler than these old crusty ones. The problem you still have is vid cards...any other heaat stacking cards. PCI slot fans are abnoxiously loud. Vented duct fans can be good, but can be loud...not to mention the digeradoo sound they somethimes make.

Here's one solution I used a while back because I just couldn't be bothered.

Build your system however you like. Make sure you have all the cooling you need. Be it fan, liquid, duct...whatever. Leve the case open on all sides. Get a huge box fan, like a 21"er. Plant it on the floor right in front of the puter. You will never hear the sound of the computer coolers over that!

Sorry if this wasn't helpfull. I was really just typing to hear myself clack.

Would you like to say that again when that little pump gives out and your CPU melts?

Allow me to quote myself...

That means bad!

If you turn on thermal protection, you won't have that problem. You get this crazed beeper for about a second, then the puter shuts down.
