Question
A silicon computer chip (k = 150 W/m · K) is attached to the top of a motherboard that is
generating heat at a rate of 10 W/cm2. A fan blows air (To = 300 K) over the topside of the
chip, resulting in a convection coefficient of h = 1 kW/m? · K. The silicon chip has a thickness, t,
of 1 mm.
A. What is the steady-state temperature (in K) on the topside of the silicon chip?
B. If the temperature distribution within the chip is linear, what is its average
temperature?
