Abstract: To increase the work efficiency of fans, reduce energy dissipation and weaken noise, a thorough study of classes of DC fans, methods and principle of fan control are made. The project of forced air cooling module is implemented by best advanced control technique and choosing up to date controller. The design is finally applied to all kinds of enclosures with forced air cooling of Tianhe supercomputer system. The control technique is proved credible and usefull by practice and result of test.
Key words: forced air cooling, pulse width modulation, duty ratio, closed loop control
