Heat sink guys,
Thanks much for this circuit. I have two of these installed in the back of my entertainment system to aid in keeping the DVR and Surround-sound amp cool during operation. They do work very well, but because the fans are mounted in the back or the entertainment center, I do not know if the fans are running or not. I am looking for any ideas that might be used to monitor the fan RPM.
Thanks again for keeping things cool!
