sinn Posted April 4, 2006 Report Share Posted April 4, 2006 Hi,im looking to design a fan that kicks in when my engine reaches approx 260F, and switches off when the temperature is lowered to approx 240F. Are there any circuits that you guys know of?? I would be using a laptop fan of 5V / 0.16A.Thanks ;D Quote Link to comment Share on other sites More sharing options...
prateeksikka Posted April 5, 2006 Report Share Posted April 5, 2006 what is the harm in keeping the fan on all the times? Quote Link to comment Share on other sites More sharing options...
sinn Posted April 5, 2006 Author Report Share Posted April 5, 2006 The engine will run too cool. It needs to stay between 240-260F for optimum operation.Thanks. Quote Link to comment Share on other sites More sharing options...
audioguru Posted April 5, 2006 Report Share Posted April 5, 2006 I don't think that a little 0.8W fan will cool the engine enough. A model airplane has the propeller and movement through the air blowing on the engine to cool it and the power of the airflow is much more than possible from a little 0.8W fan.
