For the adventurous sorts out there, I'm pleased to report that I have a
functional water-cooling system installed on the big Athlon box over here :)

Using an old but never-used automotive transmission cooling radiator,
coupled with a Swiftech MCW372-B copper/aluminum CPU water block and a small
60 GPM fountain pump, I have instantly lowered the CPU's operating
temperature by over 30 degrees F as compared to my old air cooler. Where it
used to run between a scorching (but frighteningly, well within spec)
135-145 degrees depending on room temp and CPU load, it now chugs along
happily between 100-105 degrees. And it's just "Frankenstein-ed" together
right now, sort of in the prototype phase. Once I get everything mounted
and situated permanently, I'm pretty sure that I can get it down under 100
consistently.

If anyone's ever thought about this, and has a few extra bucks to blow - you
can get complete prefab kits for a bit over $100 - I highly recommend taking
the plunge. It's very nifty :-)

Yeah it totally rocks the speed of your computer when the temperature is
lower. Most supercomputers are kept at -25º C hehe. I'm sure it'll be
standard in a couple of years to have a liquid nitrogen coolant system,
that's what they're talking about throwing into PC's.

Interesting, just have 1 concern how would you prevent water from leaking
onto the PC boards and things? the water tubes will get condensation on them
from time to time.

Don't use Water, keeping it very cold with liquid nitrogen generally
prevents condensation to form on the outside of the tubes. Or you can put
the tubes inside another tube set.

Actually, I am using water :-) The only "active" cooling at this point is
the radiator, which has two 80mm fans pulling air through it. The water
itself stays slightly above room temp, and condensation isn't an issue. Not
enough delta-T to allow it.

If/when I decide to change the cooling medium, or add in a peltier for more
active cooling, then I'll have to investigate some sealing and insulation.
Workin' just great for now, though :-)

That's cool.. you should use liquid nitrogen ;) LoL It's the best stuff for
the job.. pretty much eliminates lagginess in computations due to the heat.
It's crazy they way they did it.. there's one that was completely submerged
into the liquid medium. I thought that was pretty cool :).

liquid nitrogen hmm better have good protection from vibration dont want
them tubes breaking on you.....

You guys complicate things too much, I would just put my computer in the fridge lol

liquid nitrogen? bah, use liquid helium ;-))

too explosive around constant heat.. yes helium is explosive in certain
conditions :). Nitrogen doesn't have the same properties as the
hydrogen-helium group, so it doesn't become as unstable as fast as they
would (that's why they use helium for propellents in spacecraft). Of
course, my chem teacher would get on my case for not saying period or what
not.. but he was a quack (kinda like IA).

Yeah I was thinking the same thing...My sis had a fridge from her dorm. If
she doesn't want it and my other sis doesn't want it...I'll take out the
compressor and cool my PC with it. Don't refridgerators use freon?

Heres another thing: cool it with anti-freeze? just hope that the pipes
don't leak lol.
