Hi guys I'm in need of a fan controller, and I am looking for a solution which uses a thermal sensor to ajust the fan speed. Alternatively a diy fanmate (in denmark, they cost 39 dkr each, and cost 59 dkr to ship = 17.5 us dollars total) will do. I have access to a soldering iron, and all parts from farnell.com can be ordered for this mini project. Do you have any ideas, as i'm a newbie to designing electronics? - they need to control regular case fans - appox 4 in total. thank you in advance Edit: All suggestions welcome!
The DIY fanmate. It's actually better than the Zalman circuit which does not include the two stabilising caps C1, C2. You'll find some thermal controls too.
