Getting below room ambient with WC

post #1 of 13
Thread Starter 
ok i was just thinking of new unique ideas for case modding and cooling and had an idea come to me. water cooling suffers from one of the same problems that air does, nopt matter how good u cant get it colder than the temperature of ur room. but what if u leave the computer in ur room and put the resevoir where its colder? my computer is right next to my bedroom window and i live in new england where its below room temp outside for more than half the year. what if iu mount the resevoir right outside the window and have the tubes comming in, i would just have to leave the window open a little crack which i do sometimes anyways. if u use antifreeze or something else with a very low freezing point u can cool ur rig with below freezing liquid, whatcha think?

It will work assuming that it's winter and the temperature outside is a lot colder than indoors. You will need antifreeze mixed in with the water if the temperature outside is going to drop anywhere below 0C (so the water dosen't freeze).

The water will eventually heat up after passing through the system a few times but it will still remain below room temperature. I'd say you could probably get it around 5C. Also, your heat will go outside the house so you would not be heating your room.

Just prepare for condensation. Putting you radiator in anything colder than ambient will produce condensation on the block. <---that = bad, unless you prepare for it.

The radiator also needs to be in shade as well. Direct sunlight will probably warm things up a bit especially in summer.

Actually, I just remembered another method for cooling.... dig a hole. Underground temperature stay lower than ambient temps, I think. Once you get deep enough (but stop digging when you hit molten magma ), ground temperature is very steady. Not exactly what temps though... I've read some watercoolers do it.

Another way of getting below ambient with JUST water cooling is via evaporation. Build a evaporation cooler (aka swamp cooler, bong cooler) and you can sub-ambient.

But under ground radiators do not have adequate airflow so your computer will heat up the earth and then your loop will be hotter than it would be if your rad was in your room.
