    Too bad my dad didn't trust water cooling (fear of short circuits, water damage, etc)

    It's not water, it's polyethylene glycol, which is non-conductive. Liquid cooling is not new at all, the Cray and other supercomputers have been using it for years. The "all-in-one" kits make it easy and affordable to liquid cool the CPU. Fans make noise, bring in lots of dust and dander, and are very inefficient. Once you try these new liquid cooling kits, you'll wonder why you would do anything else...

    Interesting. I also didn't know that... polyethylene glycol... some liquid plastic replaces water.

    Yep, water is conductive (obviously) and it doesn't cool as well as some other non-conductive liquids. The liquid that I would like to use is just too expensive! Here it is... Fluorinert - Wikipedia, the free encyclopedia

    From a Wikipedia article about coolants...

    The most common coolant is water. Its high heat capacity and low cost makes it a suitable heat-transfer medium. It is usually used with additives, like corrosion inhibitors and antifreeze. Antifreeze, a solution of a suitable organic chemical (most often ethylene glycol, diethylene glycol, or propylene glycol) in water, is used when the water-based coolant has to withstand temperatures below 0 C, or when its boiling point has to be raised. Betaine is a similar coolant, with the exception that it is made from pure plant juice, and is therefore not toxic or difficult to dispose of ecologically.[1]
    Very pure deionized water, due to its relatively low electrical conductivity, is used to cool some electrical equipment, often high-power transmitters and high-power vacuum tubes.
    Heavy water is a neutron moderator used in some nuclear reactors; it also has a secondary function as their coolant. Light water reactors, both boiling water and pressurised water reactors the most common type, use ordinary (light) water.
    Polyalkylene glycol (PAG) is used as high temperature, thermally stable heat transfer fluids exhibiting strong resistance to oxidation. Modern PAG's can also be non-toxic and non-hazardous.[2]
    Cutting fluid is a coolant that also serves as a lubricant for metal-shaping machine tools.
    Oils are used for applications where water is unsuitable. With higher boiling points than water, oils can be raised to considerably higher temperatures (above 100 degrees Celsius) without introducing high pressures within the container or loop system in question.[3]

    • Mineral oils serve as both coolants and lubricants in many mechanical gears. Castor oil is also used. Due to their high boiling points, mineral oils are used in portable electric radiator-style space heaters in residential applications, and in closed-loop systems for industrial process heating and cooling.
    • Silicone oils and fluorocarbon oils (like fluorinert) are favored for their wide range of operating temperatures. However their high cost limits their applications.
    • Transformer oil is used for cooling and additional electric insulation of high-power electric transformers.

    Fuels are frequently used as coolants for engines. A cold fuel flows over some parts of the engine, absorbing its waste heat and being preheated before combustion. Kerosene and other jet fuels frequently serve in this role in aviation engines.
    Freons were frequently used for immersive cooling of e.g. electronics.
    Refrigerants are coolants used for reaching low temperatures by undergoing phase change between liquid and gas. Halomethanes were frequently used, most often R-12 and R-22, but due to environmental concerns are being phased out, often with liquified propane or other haloalkanes like R-134a. Anhydrous ammonia is frequently used in large commercial systems, and sulfur dioxide was used in early mechanical refrigerators. Carbon dioxide (R-744) is used as a working fluid in climate control systems for cars, residential air conditioning, commercial refrigeration, and vending machines.
    Heat pipes are a special application of refrigerants.

    I think water has the highest heat capacity but the most important at cooling seems to be also the highest heat transfer and there are probably some of those polyethylene stuff that achieves that.

    As seen in practice, aluminum coolers have a high heat transfer because they can cool down very fast but they also become hot pretty fast. With water is the opposite, it gets hot very slow but once hot, it also cools down very slow (can store more heat = the higher capacity). So once you have some fans dissipating heat, the transfer is all that matters not the capacity, especially if you get rid of disadvantages such as conductivity (that water has) involved.

    Water is the king of cooling as seen in nuclear power plants but in (precision) electronics we cannot allow spills of water that's why other cooling materials join forces.

    Thanks for all the info!

    Thank you Rover and a very Happy Easter to you and yours! We just came back from church and we're having the family over tomorrow, so Beth is baking pies and cooking food. Our dog is strategically placed in the center of the kitchen, waiting for anything that falls on the floor!

    Just now... Low temps at 100% CPU


    Look at these temps and note the CPU is overclocked at 4.5GHz and CPU is at 100% (folding@home)!
