Rather than joining a new forum for this question, I thought I'd post here.
I'm looking to make a very simple PWM fan controller for my computer. I've been searching all day, and it seems like everything is either too complex, parts are discontinued, or it's user controlled rather than temperature controlled. Finally, I've found a design that looks fairly simple and easy to make, but I've run into a problem, I don't know where to find the MOSFET (I think ?).
The designers page is here: http://microblog.routed.net/2007/06...re-based-fan-controller-without-a-thermistor/ with a link to his schematic here: http://microblog.routed.net/wp-content/uploads/2007/06/temp-fan.pdf
What I'm looking for is just a simple PWM, temperature dependent fan controller. I don't need anything complicated like RPM meters or anything, so I'd like to be able to use the simple 2 wire case fans.
This so far looks the best to me because of it's simple design, and I was able to find quite a few of the parts at Parts Express.
Does anybody have help for me on this design or have suggestions for a different design?
PS - noob to electronic design and soldering - KISS would be appreciated.
