Default Re: Fan speed control by OP of amp.

I think you missed the series resistor (as short wave points out)!

Better to monitor the temperature though, it could get annoying with the fan clicking on and off if you listen to something with a high dynamic range. Maybe use a low voltage DC fan and use proportional control ?
