No stickies and I dont understand most of the threads... So I decided to make one

PLease help un noobifie me. Im looking for more out of watercooling. Just stock WC isnt enough for me.. I want to push my 3500 and my 6800 ultra to the limits...

I've heard peltier, phase changing, and chillers. But I have no idea what these mean, the concepts behind them, pro's, con's, and effectivness of any of them....

So can someone please explain or throw some links at me. I would appreciate it very very much.

Thanks

Aloha,

my name is mike and i'm also a noob to extreme cooling. however i did a little homework so hope this helps

TEC (thermo electric cooling) / Peltier
What it is: You can create the Peltier effect with a battery, two pieces of copper wire and a piece of bismuth or iron wire. Just connect the copper wires to the two poles of the battery, and then connect the bismuth or iron wire between the two pieces of copper wire. The bismuth/iron and copper must touch -- it is this junction that causes the Peltier effect.
The junction where current flows from copper to bismuth will get hot, and the junction where current flows from bismuth to copper the junction will get cold. The maximum temperature drop is about 40 F from the ambient temperature where the hot junction is located. (borrowed from http://home.howstuffworks.com/refrigerator6.htm [HowStuffWorks.com - Refrigerators Pg 6 - Electric Coolers])
Application: The most effecient spot to place a TEC is directly on the cpu die. A 226w peltier should be sufficient for today's cpus. However you will need a standalone psu just for the TEC. 80w units are also sold, but from what i've read here, you'll need more watts than that to cool down the cpu at a level that'll make it's application worthwhile. if you need further proof, do your own research.
Oh yeah, this sucker puts off as much heat as it takes to cool the opposite side, so you'll need to chill the hot side with WC, chilled if you prefer (which is covered next).
Where to buy: local a/c repair shop, or http://www.frozencpu.com/cgi-bin/fr...tiers Kits and Coldplates/mp=menu_search.html (www.frozencpu.com)

CHILLER
unsure if i have this in the right category because i haven't done adequate research on this (so please correct me if i'm wrong so i can learn more about this). simply pick up a dehumidifier from your local hardware multiplex and mount the evap unit into your WC water block. again, i'm unsure of how it works/looks so you may not have to place it directly INTO the waterblock.
anyway, go read up on dehumidifiers and air conditioners, condensation, relative humidity, dew points, and know your ambient temperature (get a digital thermometer sensor).

PHASE CHANGING
save time and buy an asetek vapochill $800 to chill your cpu to -50*. read their manuals http://www.vapochill.com or visit their forums http://forum.vapochill.com
use your chilled WC for the GPU, NB

MOISTURE
get some dielectric grease from your local hardware shop to leak proof your mobo and cards. you'll also need to pick up some insulation for your water / vapor carrying tubes.

Please critique. I wanna know what important things i'm missing or need to correct. :D

EDIT: had to edit links
