Heat Dissipation
The 50 MHz 80486DX and 66 MHz 80486DX2 are very high
performance CPUs that can rival the performance of any currently
available CPU, including RISC processors. However, there is an
undesirable side effect to the high performance — the heat
generated by high power consumption.
These CPUs can dissipate up to 5 watts of power. Since this power
is concentrated in a small area, it is necessary to remove the heat
generated by this power consumption. For this reason we have
supplied a heat sink with all American Megatrends motherboards
and CPU Cards that have a 50 MHz 80486DX or 66 MHz
80486DX2 CPU.
Since American Megatrends manufactures only the motherboard
and CPU Card system components, it has no control over operating
factors such as air flow and ambient temperature inside the
computer case. The system integrator must make sure that the 50
MHz 80486DX or 66 MHz 80486DX2 CPU always operates within
a safe operating temperature range.
