A chip with dimensions of 1 cm long and 8 mm wide stationed on an electronic board generates heat of about 0.10 W, (a) Calculate the chip surface temperature if the air temperature blown from a fan is 22 C and the forced convective heat transfer coefficient is 15 W/m2 C. (b) Calculate the chip surface temperature if the cooling fan stopped working and the natural convective heat transfer coefficient is now 8 W/m C.
