Excellent.
Are you going to expand on this by putting a temperature sensor in it as well? That way the fan can go faster when the temp is hotter and slow down to be nice and quite when the temperature is not so hot.
Anyway, good job. Keep having fun.
 

thanks smitthhyy
temperature dependent fan is a good idea.
 

Can u provide the code
