I can dream up all kinds of elaborate thermostats using thermistors or LM34/35 and an opamp driving a small relay to turn on a fan in a power supply I am building.
However, it is all getting too complicated. Anybody have any suggestions for where to get a simple make-on-rise thermostatic switch. I thought I had some in the junk box, but they turned out to be normally closed, and they open on temp rise. Also, they trip at 80C, and I would like about 50C.
