Dual speed fan driver for heat-sink / Farah Wahida Abd Aziz and Siti Rohaiza Zainol

Final Project is part of our course, structure that needs to be taken to complete our Diploma, by a student that is in the final years. The main propose that all students have to take this course is to give us opportunity to teat our skill and to gather all the knowledge that we have been studying for this few years From this kind of course ,we can learn the practical way of doing the project such as design , drawing, experimenting, testing and troubleshooting. We also can figure out the best way to improve our knowledge for the purpose of using in the future.
Nowadays, the rapid changes in quality of life require new technologies to fix with us .It is important to design new system that can make everything simpler as possible to operate.
The main function of the project is to control the speed of fan for heat-sink in CPU. Heat is the great killer of PC performance and can damage your processor and other delicate components. An efficient cooling fan can protect your PCs vital parts and boost performance. This circuit will keep the system cool to protect the component in CPU. In practice, this circuit will save current and conserve the energy. Without this device, we need to control the speed of fan manually. It will save a lots of man hour to control the speed. Furthermore, it will prolong the life of cooling fan.
