IMPLEMENTATION OF FUZZY EXPERT COOLING SYSTEM FOR CORE2DUO MICROPROCESSORS AND MAINBOARDS

Öz

The aim of this study is to construct an effective fuzzy logic based control system
for multi core (core2duo) microprocessors and mainboards. Fuzzy Expert Systems were
constructed for controlling the power delivered to CPU and mainboard cooling fans.
The CPU cooling FES consists of three inputs named as CPU temperature, CPU
frequency and CPU core voltage. The output of this FES calculates the optimum speed
of microprocessor fan and sends the speed value to the electronic fan driver circuit via
serial port. The mainboard cooling FES consists of two inputs named as CPU
temperature and the mainboard temperature. This FES calculates the optimum fan speed
and controls the power delivered to the chassis fans via electronic fan driver circuit
connected to the serial port of the computer. Safe, effective and silent cooling systems
were realized by using the FES.
