Hi, I just did a little project with an old mobo and CPU combo.. the CPU is a P4 2,4GHz Northwood socket478, which i could OC to 3GHz with no problems accept the temp... I didn't want to spend a lot of bucks on a expensive cooler for this old system, so i did some experimenting with the stock heatsink and build myself an effective watercooling system, which brought my temps down from 54c @ idle, to 25c @ idle! The way i did this was by drilling 4 holes through the heatsink and then interting 4 copper pipes in them, then i connected the copper tubes to eatchother using plastic tubing, eventually i connected one tube to a bucket of icewater, which i placed on a chair, and another to an empty bucket on the floor... so this would make the water flow from the icewater bucket, through the 4 copper pipes in the heatsink, into the empty bucket on the floor... I sucked the water trought the tubes and it worked! Allmost immediately giving me more then a 50% temp drop! When adding a small aquarium pump to this setup to avoid the bucked from running out of water, this will be a very effective fully working watercooling system... But.. i still have one small problem however; Because the heatsink and the tubes are getting so cold, they produce condens on their surfaces, so things are getting a little moisture and therefore putting the motherboard in danger... So my question is, do you guys know some way i can get rid of this condens? BTW, here are some pictures of the thing: http://pic18.picturetrail.com/VOL886/3280065/6715891/172116461.jpg http://pic18.picturetrail.com/VOL886/3280065/6715891/172116453.jpg http://pic18.picturetrail.com/VOL886/3280065/6715891/172116457.jpg Thanks in advance.

How big a role did the Heineken play in the design of this thing? LOL! "So my question is, do you guys know some way i can get rid of this condens?" Sure. Go back to air-cooling. Or at least look at how a "normal" water cooling setup is built. The water is supposed to pass thru an air-cooled radiator, not a chest full of ice water.

Well.. the Heineken played a big role on helping me designing the thing :) As for the condens, i'll have my way with some duct-tape and see what that does...

I would suggest that you not use ice water. Just cool water and that should do away with the condensation. Won't run as cool but should be ok.

You could use a foam covering for the pipes to stop the condensation. Pretty cheap, or a layer of paper towel and then duct tape... Heh, I've been contemplating making a water cooling system for fun, I've got a new radiator that is meant for a cars air conditioning system brand new and unused... I guess I should get my act together get some piping and start to water cool my old Cyrix machine!

Stop condensation: raise the water temperature above the dew point of the surrounding air.(get rid of the ice)

lagg the pipes like they do in heating systems in houses this is about 1-2cm thick foam which should keep cold in the tubes and obsorb condensation give it ago and its dirt cheap good luck and brilliant idea from Damian Pentium 4 3.2ghz @ 3.5ghz Nvdia4 Mx4000 OC@ 350/500
