Fan integrating and controlling device for e.g. personal computer, has driving circuit to connect controller unit with current source and receive adjusting signal for synchronous adjustment of drive current, where fan is powered by current

摘要

The device has a number of detection units (2) designed as a thermistor and arranged at a heat source e.g. central processing unit, where the units provide temperature change parameter signals (3). A micro controller unit (4) integrates and evaluates the signal and has a signal integration unit that detects parameter signals and determines a rotation speed adjusting signal (5). A fan driving circuit (6) connects the controller unit with a drive current source (7) and receives the adjusting signal for synchronous adjustment of drive current, where the fan is powered by the current.
