Chapter 1: Introduction
1-6 System Overheat Thermal Control
A back-up cooling fan can be hooked up to JP91, JP92 or JP93. If
the power supply fan or the processor cooling fan goes down, the
circuitry will detect an overheat temperature depending on the user
setting. It will then trigger the backup cooling fan or alarm. The
alarm can be turned on or off using JP88. JP90 is used to connect
the overheat LED. The user can set the temperature range using
JP95. A buzzer can also be connected on JP89 that will sound off
that it is time to replace the power supply fan or the CPU cooling
fan. It is important that the back-up cooling fan be installed cor-
rectly in such a way that it will not only cool down the processor but
the whole system as well.
