Water chilling: Now we are getting out of the basics, and more into the advanced usage of a watercooling system. Chilling is to make your water cooler than its surroundings. This is usually done with a phase change unit, such as a fridge, air conditioner, or dehumidifyer. DO NOT USE A MINIFRIDGE! THIS IS ALWAYS THE FIRST QUESTION EVERYONE ASKS! It will not hold up to the load. An air conditioner over 5000 BTU will usually cut it, and keep your water nice and cool. A 40 pint dehumidifier should also work.To get this to chill your water, you should gut it, and put the cooling coils from the unit in your reservoir, or, build a new reservoir. This will probably require you to build an out-of-case place for your stuff. Now: That's the easy part. Now, you need to condensation proof your motherboard. You need hose insulators, and something to insulate your waterblock. While chilling, the water may come to a lower temperature than 0 degrees Celcius. For those of you who don't know, that is frozen water. So, we need to add something with a lower freezing point, such as our good friend alcohol, or antifreeze. However, antifreeze has TERRIBLE cooling capacities, so alcohol/water or just plain windshield wiper fluid is what you should probably go for.
