Condensation Question?

post #1 of 20
Thread Starter 
What temperature does condensation start in any cooling application? I will be building a water set-up in the future and wanted to know because I plan to get the water as cold as possible with a huge resovior. I also need some info on getting my DS3 ready for the set-up with something to block the condensation so it doesn't ruin my parts. Thanks OCN.

think of a warm room in your house and its cold outside and you look at the fogged up window.

Now just imagine that window is your motherboard...lol

When you get below ambient temperature, it causes oxygen to cool to liquid.

Quote:
Water vapor from air which naturally condenses on cold surfaces into liquid water is called dew. Water vapor will only condense onto another surface when that surface is cooler than the temperature of the water vapor, or when the water vapor equilibrium in air, i. e. saturation humidity, has been exceeded. When water vapor condenses onto a surface, a net warming occurs on that surface.
Basically, when it gets so cold, the air around the cold surfaces will turn into dew, hence condensation occurs. It's basically oxygen turning into water. This happens when a surface gets colder than the ambient temperature around it.

It's not oxygen turning to water... (O2 + H does not make H2O by itself). It is not a chemical reaction. It is just water vapor condensing. You can reduce condensation by using a dehumidifier.
Once again...

Double post?

Don't worry about condesation with just watercooling since it won't happen. You would need some form of active cooling... evaporation, peltier, phase, DICE, LN2.

The dew points depends on humidity.
