TB063: An Integrated Fan Speed Control Solution can Lower System Costs, Reduce Acoustic Noise, Power Consumption & Enhance System Reliability - Microchip Application Note Published 24-Feb-03 (app note added 6/06)

TC64X/TC64XB Demo Board for Fan Speed Controllers - Fan control module allows the user to quickly prototype fan control circuits based on the TC642 or TC646 PWM Fan Control IC's. Its uses though hole components for easy user assembly and evaluation. (app note added 6/06)

Temperature monitor & fan Controller reduce fan noise - 01-May-01 Issue of EDN The scheme in Figure 1 reduces system acoustic noise by running system fans at their optimum speeds for a given temperature. IC1 combines ±1°C-accurate temperature measurement of three temperatures with automatic fan-speed control of two channels. A two-wire serial interface allows you to oversee critical temperature and fan-speed data..... [Design Idea by David Hanrahan, Analog Devices Inc, Limerick, Ireland]

Temperature-controlled 12V dc Fan - Suitable for computer cooling fans. LED motor speed indicator. (electronic design added 6/07)

Temperature-measurement scheme uses IR sensor and sigma-delta ADC - 3-Apr-03 Issue of EDN Many noncontact temperature-measurement systems use infrared sensors, such as thermopiles, which can detect small amounts of heat radiation. Biomedical thermometers that measure the temperature of an ear or a temple use noncontact temperature measurement, as do automotive-HVAC systems that adjust temperature zones based on the body temperature of passengers..... [Design Idea by Albert O'Grady and Mary McCarthy, Analog Devices, Limerick, Ireland]

Thermal Cooling Fan Controller - As we begin to enjoy those lazy hazy days of summer, the most important thing on most of our minds is how to keep cool during those hot days. For some of us that means turning up the old air conditioner and sipping on a nice cold glass of our favorite soft drink. However, we often forget about an equally important..... [Radio Amateur Society of Norwich]

Thermo Cooling Fan - Use a 12V computer fan to cool your amp. Uses diode temperature sensor f.....

Use a PWM fan controller in an EMI susceptible circuit - 16-Feb-06 Issue of EDN Control it with either an external negative-temperature-coefficient thermistor or a PIC microcontroller and its SMBus serial-data bus..... [Design Idea by Dimitri Danyuk, Niles Audio Corp; Edited by Brad Thompson and Fran Granville]

Using the ADT7461 as a Multichannel Temperature Sensor - AN-702 Analog Devices Application Note (app note added 2/06)

ZXBM200x Series of Variable Speed 2-Phase Fan Motor Controller - Zetec Semiconductors Applications NotesThis applications document is intended to aid users in their development of the controller electronics for fan and blower motors using the ZXBM200x series of variable speed, 2-phase, DC brushless motor controllers. (app note added 2/06)
