I want to make that little circuit for my ATNG AP-500X that has no temp control on the fan. I've got everything but I am having a hard time finding a 470 ohm thermistor.
The closest I can find that I have laying around (I want to just use parts I have as much as possible) is a 50 ohm thermistor out of a sunpro.
I assume I will have to play with the value of the other resistor. For a 470ohm thermistor, I will also need a 2.2K resistor. On the data sheet for the LM317T it shows a 220 ohm resistor in place of the thermistor and a 5K resistor in place of the 2.2K. So I was thinking when using a 50ohm thermistor I may want to use something like a 10K resistor. Am I on the right track, or completely off?
