few watercooling ?'s fridges and electrics

lo all,
as this is my first post u guys are prolly thinkin stupid n00b and also that the answers to my question can be found with a search.
well i did search a couple of times but didnt really find n e thing.

After my exams I will be setting up a water cooling system. the res will be in my fridge, the rad will be in a sump in the fridge and that will be cooled by water and ice in the sump. the fridge is running between -5 and 0 degrees C (so maybe its a freezer) n e way ive been testing it and it has kept some ice frozen for 2 days now but hasnt frozen my coke.
n e way ive read that water under ambient will cause condensation and ive also read that this is all determined by some temp or other. all i really want to know is the chances of getting condensation in my system with this set up.

question 2, at the moment all the cooling bits in the rig are copper except the rad which is Aluminium and from my electronics lessons i know that two disimilar metals in a current of water creats a soft cell battery and so a voltage and this is very bad for the computer. is there any way i can protect my rad from turning the rig into a computer killer.

cheerz any 1 who answers ill ow u 1

in a normal watercooling system, the lowest temprature you can get is ambient - nothing nower because you are cooling the radiator with that air temp.

however you are cooling your radiator with a freezer/fridge so the lowest temp is the fridge temprature. the best way to prevent condensation is to get some foam pipe insulation and put it on the pipes to and possably from the waterblock. you may also need to insulate the waterblock, there are directions here on what to do: http://www.procooling.com/articles/html/super_cooling_and_insulation_-.shtml and here: http://www.procooling.com/articles/html/mounting_and_sealing_the_water.shtml and here: http://www.procooling.com/articles/html/chems_of_oc_n_and_super_coolin.shtml

by putting additives in the water like water wetter (get it here :www.overclockingstore.co.uk) and in your case you will also need to put it antifreeze should prevent anything from happening, including bacteria growth, Electrolysis and other nasty stuff

there are good articles on the front page of people tring to do the same thing as you: http://www.overclockers.com/tips798/

have fun and good luck with you exams - i have mine too.

those links helped alot.

you may need to insulate the mobo too, i would just to feel safe.

heres a few links on insulating the mobo with neoprene and dielectric grease, for the socket pins. Its really not all that difficult.

hope these help, they should.

cheerz for that aswell Malakai

I suggest you dump the idea of using your rad in the res for two reasons.

1. You may get problems with the coolant freezing in the rad which means adding more antifreeze which in turn reduces the performance of the coolant.

2. The use of the rad increases the resistance to flow of the coolant. Getting good flow of coolant is already a problem at these temps because of the increased viscosity caused by the antifreeze and the low temps involved.

Your better off making a chiller barrel out of it..
but that is hard if you don't have the tools and knowledge of refrigeration

How ever you could look for an old slurpy machine or even a small refrigerated air drier both will produce the effect your looking for

You can also reduce electrolytic action by electrically bonding dis-similar metals together, i.e. connect a wire between them.

cheerz guys,
tiger the rad wont acutally be in the res it will be in a secondary res which wont have n e thing to do with the water flowing through the system but i get what your saying.
ill just have to experiment a bit
great idead road warrior i think i might just do that
