STD 6-Channel PC Fan Controller
License: Public Domain
Up to 6 Fans Intelligent controller for PC based on STM32F070.
• All 6 fans controlled by PWM.
• 4 of them with the ability to adjust the supply voltage (three- or two-wire fans).
• 128 steps of smooth linear (!) voltage adjustment.
• P-channel MOSFETs in DC-DC, allowing almost lossless transmission of power to the fans (100% duty cycle).
• Full shutdown possibility for each DC-DC.
• DC-DC output currents up to 4A (>15 Watts per channel).
• Continued operation even when the microcontrollers fail.
• DC-DC supply voltage and output voltage sensors.
• 2 buses for digital temperature sensors (up to 16 DS18B20 sensors).
• Temperature sensors built into digiPOTs and microcontroller.
• Tracking of the built-in PC temperature sensors (MB, CPU, GPU, HDD) via the control software.
• Power and error indicators + alarm buzzer.
• IPS display 240x240.
• 32.768 kHz crystal for accurate fan speed measurement.
• USB connection.
• Control software (at the first stage only Windows, but I will open the exchange protocol and all other sources).
• Different power options: Molex (12V + 5V), Power 12V + USB, Molex + Power 12V, Single PS 5-18V.
• Automatic configuration and connected fans detection.
• Firmware update via USB.
• Mounting holes for the HDD 2.5" holder
The device is intended for use in cooling systems of personal computers and other professional equipment.
Project Overview (English subtitles): https://youtu.be/2WcZQeidf3s
ATTENTION!!! I haven't finished the firmware yet, and I've just started coding the management software. As soon as I finish them, I'll post all the sources and the compiled binaries.
Intelligent fan controller based on STM32F070 microcontroller.
The device can poll a set of temperature sensors, each of which has a certain coefficient of influence on each of the 6 controlled fans. Thus, it is possible to control several cooling zones of the device with a complex internal geometry. Multiple operating modes and cooling profiles (high, medium, low) available. The device is controlled via USB.
