Are bigger heat sinks better?
Are bigger heat sinks better? The larger the heatsink, the more readily it can dissipate heat. On this note, a larger base plate surface area means better transfer of heat from the CPU to the pipes and more room for mounting error. Materials. Copper has about twice the thermal conductivity of aluminum and simply makes […]

Is condensation a spontaneous process?
Is condensation a spontaneous process? Recall that the condensation of water vapor occurs spontaneously at temperature below 100°C but not above. Condensation is an exothermic process; to see this, consider that the reverse process, evaporation, obviously requires heat input. Therefore, condensation only occurs at lower temperatures. Why does condensation happen? Condensation happens one of two […]
