Computer Thermodynamics

  1. Jun 16, 2005 #1
    Greetings All,

    I have a computer project coming up and wanted to take an approach with physics. I want to use a thermoelectric cooling device to cool water in a liquid cooled computer. Heres the question: How can I calculate the amount of heat in Watts generated by the certain microchips and processors in the computer? If I know the temperature of the chip, isn't there a simple way to convert that temperature to its equivalent in Watts?

    Any help is appreciated. Thanks.

    How about just knowing the power produced by each component? That should be published data on each component.

    The heat generated /unit time by any electrical resistance is [itex]I^2R[/itex] or [itex]V^2/R[/itex] or [itex]VI[/itex]. So, if you have the voltage supplied and the current, you will be able to work out the heat given off.

    I suspect that the most critical factor, however, will not be the amount of heat given off, but the speed at which heat can be exchanged with your coolant at the desired working temperature of the chip.
