PC temperature control
This is a standalone temperature and fan monitoring and control unit for the PC. It uses the temperature readings to adjust fan speeds in order to regulate temperature and noise. The system is flexible in that it can be configured to be either completely autonomous, or set up to be configurable. It is also highly configurable in the setting up of the features and parameters. The entire unit is controlled by the 2 Atmel Mega32 MCUs – 1 for the main control unit and 1 for the RF remote control, with inputs to the ADC (for thermal sensors), port pins, RS232 serial connection and output to the LCD, port pins and RS232 serial connection. The RF remote control controls specific settings of the unit. The main unit is powered off a standard 4-pin PC Molex power connector while the remote control is powered off a 9V battery. [via]
