    Ja, igen, a korróziót nem. Az eredeti hozzászólásban az algásodásról volt szó, én most csak arra figyeltem.

    Weareus: ez nagyon jó összefoglaló, köszi!

    Sőt, mindjárt egy kis érdekesség belőle:
    Adding antifreeze to your PC water-cooling system will increase the viscosity of the coolant and can reduce the overall flow rate thru the system. In addition, the thermal conductivity and specific heat of glycol is not as good as water. Combining these factors may result in a measurable drop in cooling performance.

    Another potential disadvantage of using glycol based antifreeze for corrosion protection in your PC water-cooling system is that it may not provide optimal protection due to a relatively low concentration. Antifreeze is designed to be mixed with water at a 50:50 mix. Most PC enthusiast use a 15%~20% antifreeze to water mix. This means the concentration of corrosion inhibitors is much lower than what the manufacturer intended. Increasing the coolant mix to 50:50 would significantly decrease the coolant’s flow rate and ability to transfer/transport heat.

    Most water-cooled PCs operate at ambient room temperatures, so there is usually no need to protect the water from freezing or to extend the boiling point. Systems that incorporate some form of active cooling (Peltier devices, refrigeration, etc.) may require freeze protection. The first thing that comes to most people’s mind is automotive antifreeze. But for all the reasons listed above, glycol based antifreeze may not be the best choice.

    Reasons to use antifreeze:

    Readily available
    Provides basic corrosion inhibition

    Reasons not to use antifreeze

    Toxic to humans and animals
    Higher viscosity than water (lower flow rates)
    Thermal conductivity and specific heat not as good as water
    Becomes even more viscous at lower temperatures
    Diluted corrosion inhibitors may not provide optimum protection

    Szerintem ez alapján nem igazán ajánlott.

    Én egyébként mindent tökéletesen úgy csináltam, ahogy az összefoglalóban írtátok, és nekem tökéletesen bevált. Az tény, hogy picit bemattult a tartály, de ez nem zavar. :)
