"electrical genuis background"??? lol, yeah right! Just a hobbyist...
Anyway, to make one out of discrete components would be fairly easy: Maybe a Schmitt trigger (op-amp or comparator based), with a thermistor v-divider on one side and a fixed 5v regulator as a reference on the other. Drive a small NPN transistor configured as a switch to turn on the fan. Or, see if you can find an all-in-one thermal switch IC. Most of the ones I know of are thermally controlled fan speed controllers, not on/off controllers. |

Hmm, the thermally controlled fan speed thingy sounds interesting.
If it would be "fairly easy" to build, do you want to make me one? Funding will not be a problem. How big do you think it would be? Size of a bec, or larger, like a house brick? |
