Test Procedure to Assure Proper Operating Temperatures:
1. Install the AMI motherboard or AMI CPU card in a fully
loaded system.
2. Install a temperature sensor (such as a thermocouple) so
that the surface of the heat sink can be measured without
opening the case.
3. Turn on the system and run a diagnostics utility program
such as AMI Diag for at least one hour.
Expected Results
If the temperature on the surface of the heat sink is 75 degrees
centigrade or below, there will be no problem with the operation of
the computer.
Identifying a Problem
If the temperature exceeds 75 degrees centigrade, the system
integrator must take the necessary measures to ensure that the
80486DX CPU does not overheat.
Potential Solutions
1. Install a fan to increase the air flow over the CPU. Some
power supplies may have larger or more powerful fans.
2. Install a different heat sink with a greater surface area.
3. Different case styles may have better ventilation allowing
for more air-flow over the CPU.
