Note: The cooling fan and heat sink are required for Pentium processors.
Please pay close attention to the direction of the CPU and cooling fan
during installation. Position the cooling ventilator directly facing the
regulator heat sink, which is located beside the CPU socket. This will
reduce the overheating of the regulator and increase the reliability of
the system.
