For my senior design project I think I'm gonna make a fan controller for a PC and have it intergrated into the PC through maybe a USB port or something. Are there any ideas on what would make a good product and what kinda features that people would incorportated into it? I would probably use a PIC (microcontroller) to interface to the computer. Probably have user settings through a GUI of some kind to change system temp and then the fans would speed up and slow down accordingly to the RPM sensor and such provided by the three terminal fan. Maybe find the vector of the CPU temp in the bios or something and use that for CPU throttling.. Maybe have super quite operation and high performance settings.. I know there are some out there that are like this. The one I have has shitting temp sensors, and doesn't regulator the fan speed automatically. This project is still a while off, but I want to start getting some user feedback on what people would want..
