Temperature Controlled FAN using ATtiny10
The electrons movement in electronic components lead to the generation of heat which when beyond certain thresholds, prevents some components from functioning properly and in others could lead to a catastrophic breakdown. For this reason, the topics of ventilation, overheating, and...Continue Reading
Laptop Bench Power Supply with FAN controller
Zak Kemble build another great project. This time it's a bench power supply with a laptop brick input. The power supply needed sufficient cooling so he added a small Fan and a controller a the edge of the board. He writes: Many years ago (September 2009) I made a simple bench power...Continue Reading
Do You Need to Use a Fan for Cooling with the New Raspberry Pi 4?
Alasdair Allan @ blog.hackster.io explores this question in details. Every time a new Raspberry Pi is released there are mutterings about the thermal control of the new board. But this time, it looks like it might well be necessary to add some passive, or even active, cooling to the...Continue Reading

Infineon’s Solutions for Pumps and Fans
Fans and pumps can be found in various applications including home appliances and industrial systems. Driven by more stringent regulations and growing awareness around energy efficiency, this segment is increasingly being shaped by rising demand for inverterization, especially in pumps...Continue Reading
Fan Speed Control Is Cool!
App note from Maxim Integrated about their MAX6650 and MAX6651 fan controllers chip. Temperature-based fan control is a necessity in a growing number of systems, both to reduce system noise and to improve fan reliability. When fan control is augmented by fan-speed monitoring, a...Continue Reading
Temperature Controlled Fan With LED Status
This is a simple fan controller with single LED temperature status light using an ATtiny85 microcontroller and DS18B20 temperature sensor. The fan is turned on/off based on temperature sensed and the controller goes in sleep mode when the temperature drop below a predefined...Continue Reading
PWM Fan controller
Lucky Resistor has build a PWM fan controller using Arduino and DHT22 sesnsors. The fan controller described on this project page, controls one or more PWM controlled 12V PC fans. It uses the input from two precise DHT22 based temperature sensors. The MCU is an Arduino Uno, which is...Continue Reading
